+The following instructions apply if you have a Linux platform and want
+libpcap to support the 'ACN' WAN/LAN router product from from SITA
+(http://www.sita.aero)
+
+This might also work on non-Linux Unix-compatible platforms, but that
+has not been tested.
+
+See also the libpcap INSTALL.txt file for further libpcap configuration
+options.
+
+These additions/extensions have been made to PCAP to allow it to
+capture packets from a SITA ACN device (and potentially others).
+
+To enable its support you need to ensure that the distribution has
+a correct configure.in file; that can be created if neccessay by
+using the normal autoconf procedure of:
+
+aclocal
+autoconf
+autoheader
+automake
+
+Then run configure with the 'sita' option:
+
+./configure --with-sita
+
+Applications built with libpcap configured in this way will only detect SITA
+ACN interfaces and will not capture from the native OS packet stream.
+
+The SITA extension provides a remote datascope operation for capturing
+both WAN and LAN protocols.  It effectively splits the operation of
+PCAP into two halves.  The top layer performs the majority of the
+work, but interfaces via a TCP session to remote agents that
+provide the lower layer functionality of actual sniffing and
+filtering. More detailed information regarding the functions and
+inter-device protocol and naming conventions are described in detail
+in 'pcap-sita.html'.
+
+pcap_findalldevs() reads the local system's /etc/hosts file looking
+for host names that match the format of IOP type devices.  ie.  aaa_I_x_y
+and then queries each associated IP address for a list of its WAN and
+LAN devices.  The local system the aggregates the lists obtained from
+each IOP, sorts it, and provides it (to Wireshark et.al) as the
+list of monitorable interfaces.
+
+Once a valid interface has been selected, pcap_open() is called
+which opens a TCP session (to a well known port) on the target IOP
+and tells it to start monitoring.
+
+All captured packets are then forwarded across that TCP session
+back to the local 'top layer' for forwarding to the actual
+sniffing program (wireshark...)
+
+Note that the DLT_SITA link-layer type includes a proprietary header
+that is documented as part of the SITA dissector of Wireshark and is
+also described in 'pcap-sita.html' for posterity sake.
+
+That header provides:
+- Packet direction (in/out) (1 octet)
+- Link layer hardware signal status (1 octet)
+- Transmit/Receive error status (2 octets)
+- Encapsulated WAN protocol ID (1 octet)

-<a name="rfc.section.1"></a><h3>1.&nbsp;Objectives</h3>
-
-<p>The problem of exchanging packet traces becomes more and more critical every day; unfortunately, no standard solutions exist for this task right now. One of the most accepted packet interchange formats is the one defined by libpcap, which is rather old and does not fit for some of the nowadays applications especially in terms of extensibility.
-</p>
-<p>This document proposes a new format for dumping packet traces. The following goals are being pursued:
-</p>
-<ul class="text">
-<li>Extensibility: aside of some common functionalities, third parties should be able to enrich the information embedded in the file with proprietary extensions, which will be ignored by tools that are not able to understand them.
-</li>
-<li>Portability: a capture trace must contain all the information needed to read data independently from network, hardware and operating system of the machine that made the capture.
-</li>
-<li>Merge/Append data: it should be possible to add data at the end of a given file, and the resulting file must still be readable.
-</li>
-</ul>

-</p>
-<p>The structure of the blocks allows to define other blocks if needed. A parser that does non understand them can simply ignore their content.

-<a name="rfc.section.2.3"></a><h4><a name="anchor4">2.3</a>&nbsp;Block Hierarchy and Precedence</h4>
-
-<p>The file must begin with a Section Header Block. However, more than one Section Header Block can be present on the dump, each one covering the data following it till the next one (or the end of file). A Section includes the data delimited by two Section Header Blocks (or by a Section Header Block and the end of the file), including the first Section Header Block.
-</p>
-<p>In case an application cannot read a Section because of different version number, it must skip everything until the next Section Header Block. Note that, in order to properly skip the blocks until the next section, all blocks must have the fields Type and Length at the beginning. This is a mandatory requirement that must be maintained in future versions of the block format.
-</p>
-<p><a href="#fssample-SHB">Figure 2</a> shows two valid files: the first has a typical configuration, with a single Section Header that covers the whole file. The second one contains three headers, and is normally the result of file concatenation. An application that understands only version 1.0 of the file format skips the intermediate section and restart processing the packets after the third Section Header.

-<p>Data contained in each section will always be saved according to the characteristics (little endian / big endian) of the dumping machine. This refers to all fields that are saved as numbers and that span over two or more bytes.
-</p>
-<p>The approach of having each section saved in the native format of the generating host is more efficient because it avoids translation of data when reading / writing on the host itself, which is the most common case when generating/processing capture dumps.

-<p>TODO Probably we have to specify something more here. Is what we're saying enough to avoid any kind of ambiguity?.

-<p>The Section Header Block does not contain data but it rather identifies a list of blocks (interfaces, packets) that are logically correlated. This block does not contain any reference to the size of the section it is currently delimiting, therefore the reader cannot skip a whole section at once. In case a section must be skipped, the user has to repeatedly skip all the blocks contained within it; this makes the parsing of the file slower but it permits to append several capture dumps at the same file.

-<li>Timestamp (High): the most significative part of the timestamp. in standard Unix format, i.e. from 1/1/1970.

-<li>Timestamp (Low): the less significative part of the timestamp. The way to interpret this field is specified by the 'ts_accur' option (see <a href="#formatidb">Figure 4</a>) of the Interface Description block referenced by this packet.

-</li>
-<li>Packet Len: actual length of the packet when it was transmitted on the network. Can be different from Captured Len if the user wants only a snapshot of the packet.
-</li>
-<li>Packet Data: the data coming from the network, including link-layer headers. The length of this field is Captured Len. The format of the link-layer headers depends on the LinkType field specified in the Interface Description Block (see <a href="#sectionidb">Section 3.2</a>) and it is specified in Appendix XXX (TODO).

-
-<p>The Simple Packet Block is a lightweight container for storing the packets coming from the network. Its presence is optional.
-</p>
-<p>A Simple Packet Block is similar to a Packet Block (see <a href="#sectionpb">Section 3.3</a>), but it is smaller, simpler to process and contains only a minimal set of information. This block is preferred to the standard Packet Block when performance or space occupation are critical factors, such as in sustained traffic dump applications. A capture file can contain both Packet Blocks and Simple Packet Blocks: for example, a capture tool could switch from Packet Blocks to Simple Packet Blocks when the hardware resources become critical.
-</p>
-<p>The Simple Packet Block does not contain the Interface ID field. Therefore, it must be assumed that all the Simple Packet Blocks have been captured on the interface previously specified in the Interface Description Block.

Therefore, each tool can be either read the content of the optional fields (if any), or skip them at once.
-</p>
-<p>Skipping all the optional fields at once is straightforward because most of the blocks have a fixed length, therefore the field Block Length (present in the General Block Structure, see  <a href="#sectionblock">Section 2.1</a>) can be used to skip everything till the next block.

-<ul class="text">
-<li>Option Type (2 bytes): it contains the code that specifies the type of the current TLV record. Option types whose Most Significant Bit is equal to one are reserved for local use; therefore, there is no guarantee that the code used is unique among all capture files (generated by other applications). In case of vendor-specific extensions that have to be identified uniquely, vendors must request an Option Code whose MSB is equal to zero.

-<li>Option Length (2 bytes): it contains the length of the following 'Option Value' field.

-<li>Option Value (variable length): it contains the value of the given option. The length of this field as been specified by the Option Length field.

-In the most complex case, it can be used as a repository for heterogeneous information.
-In every case, the file remains easy to parse and an application can always skip the data it is not interested in; at the same time, different applications can share the file, and each of them can benfit of the information produced by the others.
-Two or more files can be concatenated obtaining another valid file.

-1. Objectives
-
-   The problem of exchanging packet traces becomes more and more
-   critical every day; unfortunately, no standard solutions exist for
-   this task right now. One of the most accepted packet interchange
-   formats is the one defined by libpcap, which is rather old and does
-   not fit for some of the nowadays applications especially in terms of
-   extensibility.
-
-   This document proposes a new format for dumping packet traces. The
-   following goals are being pursued:
-
-   o  Extensibility: aside of some common functionalities, third parties
-      should be able to enrich the information embedded in the file with
-      proprietary extensions, which will be ignored by tools that are
-      not able to understand them.
-
-   o  Portability: a capture trace must contain all the information
-      needed to read data independently from network, hardware and
-      operating system of the machine that made the capture.
-
-   o  Merge/Append data: it should be possible to add data at the end of
-      a given file, and the resulting file must still be readable.

-2. General File Structure
-
-2.1 General Block Structure
-
-   A capture file is organized in blocks, that are appended one to
-   another to form the file. All the blocks share a common format, which
-   is shown in Figure 1.
-
-       0                   1                   2                   3
-       0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

-      |                          Block Type                           |
-      +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
-      |                      Block Total Length                       |
-      +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
-      /                          Block Body                           /
-      /          /* variable length, aligned to 32 bits */            /
-      +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
-      |                      Block Total Length                       |
-      +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
-
-                    Figure 1: Basic block structure.
-
-   The fields have the following meaning:
-
-   o  Block Type (32 bits): unique value that identifies the block.
-      Values whose Most Significant Bit (MSB) is equal to 1 are reserved
-      for local use. They allow to save private data to the file and to
-      extend the file format.
-
-   o  Block Total Length: total size of this block, in bytes. For
-      instance, a block that does not have a body has a length of 12
-      bytes.
-
-   o  Block Body: content of the block.
-
-   o  Block Total Length: total size of this block, in bytes. This field
-      is duplicated for permitting backward file navigation.
-
-   This structure, shared among all blocks, makes easy to process a file
-   and to skip unneeded or unknown blocks. Blocks can be nested one
-   inside the others (NOTE: needed?). Some of the blocks are mandatory,
-   i.e. a dump file is not valid if they are not present, other are
-   optional.
-
-   The structure of the blocks allows to define other blocks if needed.
-   A parser that does non understand them can simply ignore their
-   content.

-
-2.2 Block Types
-
-   The currently defined blocks are the following:
-
-   1.  Section Header Block: it defines the most important
-       characteristics of the capture file.
-
-   2.  Interface Description Block: it defines the most important
-       characteristics of the interface(s) used for capturing traffic.
-
-   3.  Packet Block: it contains a single captured packet, or a portion
-       of it.
-
-   4.  Simple Packet Block: it contains a single captured packet, or a
-       portion of it, with only a minimal set of information about it.
-
-   5.  Name Resolution Block: it defines the mapping from numeric
-       addresses present in the packet dump and the canonical name
-       counterpart.
-
-   6.  Capture Statistics Block: it defines how to store some
-       statistical data (e.g. packet dropped, etc) which can be useful
-       to undestand the conditions in which the capture has been made.
-
-   7.  Compression Marker Block: TODO
-
-   8.  Encryption Marker Block: TODO
-
-   9.  Fixed Length Marker Block: TODO
-
-   The following blocks instead are considered interesting but the
-   authors believe that they deserve more in-depth discussion before
-   being defined:
-
-   1.  Further Packet Blocks
-
-   2.  Directory Block
-
-   3.  Traffic Statistics and Monitoring Blocks
-
-   4.  Alert and Security Blocks

-   one Section Header Block can be present on the dump, each one
-   covering the data following it till the next one (or the end of
-   file). A Section includes the data delimited by two Section Header
-   Blocks (or by a Section Header Block and the end of the file),
-   including the first Section Header Block.
-
-   In case an application cannot read a Section because of different
-   version number, it must skip everything until the next Section Header
-   Block. Note that, in order to properly skip the blocks until the next
-   section, all blocks must have the fields Type and Length at the
-   beginning. This is a mandatory requirement that must be maintained in
-   future versions of the block format.
-
-   Figure 2 shows two valid files: the first has a typical
-   configuration, with a single Section Header that covers the whole
-   file. The second one contains three headers, and is normally the
-   result of file concatenation. An application that understands only
-   version 1.0 of the file format skips the intermediate section and
-   restart processing the packets after the third Section Header.

-2.4 Data format
-
-   Data contained in each section will always be saved according to the
-   characteristics (little endian / big endian) of the dumping machine.
-   This refers to all fields that are saved as numbers and that span
-   over two or more bytes.
-
-   The approach of having each section saved in the native format of the
-   generating host is more efficient because it avoids translation of
-   data when reading / writing on the host itself, which is the most
-   common case when generating/processing capture dumps.

-3. Block Definition
-
-   This section details the format of the body of the blocks currently
-   defined.
-
-3.1 Section Header Block (mandatory)
-
-   The Section Header Block is mandatory. It identifies the beginning of
-   a section of the capture dump file. Its format is shown in Figure 3.

-                 Figure 3: Section Header Block format.
-
-   The meaning of the fields is:
-
-   o  Magic: magic number, whose value is the hexadecimal number
-      0x1A2B3C4D. This number can be used to distinguish section that
-      have been saved on little-endian machines from the one saved on
-      big-endian machines.
-
-   o  Major: number of the current mayor version of the format. Current
-      value is 1.
-
-   o  Minor: number of the current minor version of the format. Current
-      value is 0.
-
-   o  Options: optionally, a list of options (formatted according to the
-      rules defined in Section 4) can be present.
-
-   Aside form the options defined in Section 4, the following options
-   are valid within this block:

-
-   The Section Header Block does not contain data but it rather
-   identifies a list of blocks (interfaces, packets) that are logically
-   correlated. This block does not contain any reference to the size of
-   the section it is currently delimiting, therefore the reader cannot
-   skip a whole section at once. In case a section must be skipped, the
-   user has to repeatedly skip all the blocks contained within it; this
-   makes the parsing of the file slower but it permits to append several
-   capture dumps at the same file.
-
-3.2 Interface Description Block (mandatory)
-
-   The Interface Description Block is mandatory. This block is needed to
-   specify the characteristics of the network interface on which the
-   capture has been made. In order to properly associate the captured
-   data to the corresponding interface, the Interface Description Block
-   must be defined before any other block that uses it; therefore, this
-   block is usually placed immediately after the Section Header Block.
-
-   An Interface Description Block is valid only inside the section which
-   it belongs to. The structure of a Interface Description Block is
-   shown in Figure 4.

-             Figure 4: Interface Description Block format.
-
-   The meaning of the fields is:
-
-   o  Interface ID: a progressive number that identifies uniquely any
-      interface inside current section. Two Interface Description Blocks
-      can have the same Interface ID only if they are in different
-      sections of the file. The Interface ID is referenced by the packet
-      blocks.
-
-   o  LinkType: a value that defines the link layer type of this
-      interface.
-
-   o  SnapLen: maximum number of bytes dumped from each packet. The
-      portion of each packet that exceeds this value will not be stored
-      in the file.
-
-   o  Options: optionally, a list of options (formatted according to the
-      rules defined in Section 4) can be present.
-
-   In addition to the options defined in Section 4, the following
-   options are valid within this block:

-3.3 Packet Block (optional)
-
-   A Packet Block is the standard container for storing the packets
-   coming from the network. The Packet Block is optional because packets
-   can be stored either by means of this block or the Simple Packet
-   Block, which can be used to speed up dump generation. The format of a
-   packet block is shown in Figure 5.

-                     Figure 5: Packet Block format.
-
-   The Packet Block has the following fields:
-
-   o  Interface ID: Specifies the interface this packet comes from, and
-      corresponds to the ID of one of the Interface Description Blocks
-      present in this section of the file (see Figure 4).
-
-   o  Drops Count: a local drop counter. It specified the number of
-      packets lost (by the interface and the operating system) between
-      this packet and the preceding one. The value xFFFF (in
-      hexadecimal) is reserved for those systems in which this
-      information is not available.
-
-   o  Timestamp (High): the most significative part of the timestamp. in
-      standard Unix format, i.e. from 1/1/1970.
-
-   o  Timestamp (Low): the less significative part of the timestamp. The
-      way to interpret this field is specified by the 'ts_accur' option
-      (see Figure 4) of the Interface Description block referenced by
-      this packet. If the Interface Description block does not contain a
-      'ts_accur' option, then this field is expressed in microseconds.
-
-   o  Captured Len: number of bytes captured from the packet (i.e. the

-
-
-      length of the Packet Data field). It will be the minimum value
-      among the actual Packet Length and the snapshot length (defined in
-      Figure 4).
-
-   o  Packet Len: actual length of the packet when it was transmitted on
-      the network. Can be different from Captured Len if the user wants
-      only a snapshot of the packet.
-
-   o  Packet Data: the data coming from the network, including
-      link-layer headers. The length of this field is Captured Len. The
-      format of the link-layer headers depends on the LinkType field
-      specified in the Interface Description Block (see Section 3.2) and
-      it is specified in Appendix XXX (TODO).
-
-   o  Options: optionally, a list of options (formatted according to the
-      rules defined in Section 4) can be present.
-
-
-3.4 Simple Packet Block (optional)
-
-   The Simple Packet Block is a lightweight container for storing the
-   packets coming from the network. Its presence is optional.
-
-   A Simple Packet Block is similar to a Packet Block (see Section 3.3),
-   but it is smaller, simpler to process and contains only a minimal set
-   of information. This block is preferred to the standard Packet Block
-   when performance or space occupation are critical factors, such as in
-   sustained traffic dump applications. A capture file can contain both
-   Packet Blocks and Simple Packet Blocks: for example, a capture tool
-   could switch from Packet Blocks to Simple Packet Blocks when the
-   hardware resources become critical.
-
-   The Simple Packet Block does not contain the Interface ID field.
-   Therefore, it must be assumed that all the Simple Packet Blocks have
-   been captured on the interface previously specified in the Interface
-   Description Block.
-
-   Figure 6 shows the format of the Simple Packet Block.

-                 Figure 6: Simple Packet Block format.
-
-   The Packet Block has the following fields:
-
-   o  Packet Len: actual length of the packet when it was transmitted on
-      the network. Can be different from captured len if the packet has
-      been truncated.
-
-   o  Packet data: the data coming from the network, including
-      link-layers headers. The length of this field can be derived from
-      the field Block Total Length, present in the Block Header.
-
-   The Simple Packet Block does not contain the timestamp because this
-   is one of the most costly operations on PCs. Additionally, there are
-   applications that do not require it; e.g. an Intrusion Detection
-   System is interested in packets, not in their timestamp.
-
-   The Simple Packet Block is very efficient in term of disk space: a
-   snapshot of length 100 bytes requires only 16 bytes of overhead,
-   which corresponds to an efficiency of more than 86%.
-
-3.5 Name Resolution Block (optional)
-
-   The Name Resolution Block is used to support the correlation of
-   numeric addresses (present in the captured packets) and their
-   corresponding canonical names and it is optional. Having the literal
-   names saved in the file, this prevents the need of a name resolution
-   in a delayed time, when the association between names and addresses
-   can be different from the one in use at capture time. Moreover, The
-   Name Resolution Block avoids the need of issuing a lot of DNS
-   requests every time the trace capture is opened, and allows to have
-   name resolution also when reading the capture with a machine not
-   connected to the network.
-
-   The format of the Name Resolution Block is shown in Figure 7.

-
-   The fields have the following meaning:
-
-   o  IfRecv: number of packets received from the interface during the
-      capture. This number is reported as a 64 bits value, in which the
-      most significat bits are located in the first four bytes of the
-      field.
-
-   o  IfDrop: number of packets dropped by the interface during the
-      capture due to lack of resources.
-
-   o  FilterAccept: number of packets accepeted by filter during current
-      capture.
-
-   o  OSDrop: number of packets dropped by the operating system during
-      the capture.
-
-   o  UsrDelivered: number of packets delivered to the user.
-      UsrDelivered can be different from the value 'FilterAccept -
-      OSDropped' because some packets could still lay in the OS buffers
-      when the capture ended.

-   useful when reading data, but that it is not really needed for packet
-   processing. Therefore, each tool can be either read the content of
-   the optional fields (if any), or skip them at once.
-
-   Skipping all the optional fields at once is straightforward because
-   most of the blocks have a fixed length, therefore the field Block
-   Length (present in the General Block Structure, see  Section 2.1) can
-   be used to skip everything till the next block.
-
-   Options are a list of Type - Length - Value fields, each one
-   containing a single value:
-
-   o  Option Type (2 bytes): it contains the code that specifies the
-      type of the current TLV record. Option types whose Most
-      Significant Bit is equal to one are reserved for local use;
-      therefore, there is no guarantee that the code used is unique
-      among all capture files (generated by other applications). In case
-      of vendor-specific extensions that have to be identified uniquely,
-      vendors must request an Option Code whose MSB is equal to zero.
-
-   o  Option Length (2 bytes): it contains the length of the following
-      'Option Value' field.
-
-   o  Option Value (variable length): it contains the value of the given
-      option. The length of this field as been specified by the Option
-      Length field.
-
-   Options may be repeated several times (e.g. an interface that has
-   several IP addresses associated to it). The option list is terminated
-   by a special code which is the 'End of Option'.
-
-   The format of the optional fields is shown in Figure 9.

-
-   Can some other packet blocks (besides the two described in the
-   previous paragraphs) be useful?

-
-   The Fixed Length Block is optional. A file can contain an arbitrary
-   number of these blocks. A Fixed Length Block can be used to optimize
-   the access to the file. Its format is shown in Figure 12. A Fixed
-   Length Block stores records with constant size. It contains a set of
-   Blocks (normally Packet Blocks or Simple Packet Blocks), of wihich it
-   specifies the size. Knowing this size a priori helps to scan the file
-   and to load some portions of it without truncating a block, and is
-   particularly useful with cell-based networks like ATM.

-
-5.5 Directory Block (experimental)
-
-   If present, this block contains the following information:
-
-   o  number of indexed packets (N)
-
-   o  table with position and length of any indexed packet (N entries)
-
-   A directory block must be followed by at least N packets, otherwise
-   it must be considered invalid. It can be used to efficiently load
-   portions of the file to memory and to support operations on memory
-   mapped files. This block can be added by tools like network analyzers
-   as a consequence of file processing.
-
-5.6 Traffic Statistics and Monitoring Blocks (experimental)

-   traffic monitoring information. They could be use to store data
-   collected from RMON or Netflow probes, or from other network
-   monitoring tools.
-
-5.7 Event/Security Block (experimental)

-   o  skipped, if the application doesn't know how to do with it
-
-   o  processed independently by the packets. In other words, the
-      applications skips the packets and processes only the alerts
-
-   o  processed in relation to packets: for example, a security tool
-      could load only the packets of the file that are near a security
-      alert; a monitorg tool could skip the packets captured while the

-6. Conclusions
-
-   The file format proposed in this document should be very versatile
-   and satisfy a wide range of applications. In the simplest case, it
-   can contain a raw dump of the network data, made of a series of
-   Simple Packet Blocks. In the most complex case, it can be used as a
-   repository for heterogeneous information. In every case, the file
-   remains easy to parse and an application can always skip the data it
-   is not interested in; at the same time, different applications can
-   share the file, and each of them can benfit of the information
-   produced by the others. Two or more files can be concatenated
-   obtaining another valid file.

-<t>This document describes a format to dump captured packets on a file. This format is extensible and it is currently proposed for implementation in the libpcap/WinPcap packet capture library.</t>

-<section title="Objectives">
-<t>The problem of exchanging packet traces becomes more and more critical every day; unfortunately, no standard solutions exist for this task right now. One of the most accepted packet interchange formats is the one defined by libpcap, which is rather old and does not fit for some of the nowadays applications especially in terms of extensibility.</t>
-<t>This document proposes a new format for dumping packet traces. The following goals are being pursued:</t>
-<list style="symbols">
-<t>Extensibility: aside of some common functionalities, third parties should be able to enrich the information embedded in the file with proprietary extensions, which will be ignored by tools that are not able to understand them.</t>
-<t>Portability: a capture trace must contain all the information needed to read data independently from network, hardware and operating system of the machine that made the capture.</t>
-<t>Merge/Append data: it should be possible to add data at the end of a given file, and the resulting file must still be readable.</t>

-<section anchor="sectionblock" title="General Block Structure">
-<t>A capture file is organized in blocks, that are appended one to another to form the file. All the blocks share a common format, which is shown in <xref target="formatblock"/>.</t>

-<t>The fields have the following meaning:</t>
-
-<list style="symbols">
-<t>Block Type (32 bits): unique value that identifies the block. Values whose Most Significant Bit (MSB) is equal to 1 are reserved for local use. They allow to save private data to the file and to extend the file format.</t>
-<t>Block Total Length: total size of this block, in bytes. For instance, a block that does not have a body has a length of 12 bytes.</t>
-<t>Block Body: content of the block.</t>
-<t>Block Total Length: total size of this block, in bytes. This field is duplicated for permitting backward file navigation.</t>
-</list>
-
-<t>This structure, shared among all blocks, makes easy to process a file and to skip unneeded or unknown blocks. Blocks can be nested one inside the others (NOTE: needed?). Some of the blocks are mandatory, i.e. a dump file is not valid if they are not present, other are optional.</t>
-<t>The structure of the blocks allows to define other blocks if needed. A parser that does non understand them can simply ignore their content.</t>
-</section>
-
-<section title="Block Types">
-<t>The currently defined blocks are the following:</t>
-<list style="numbers">
-<t>Section Header Block: it defines the most important characteristics of the capture file.</t>
-<t>Interface Description Block: it defines the most important characteristics of the interface(s) used for capturing traffic.</t>
-<t>Packet Block: it contains a single captured packet, or a portion of it.</t>
-<t>Simple Packet Block: it contains a single captured packet, or a portion of it, with only a minimal set of information about it.</t>
-<t>Name Resolution Block: it defines the mapping from numeric addresses present in the packet dump and the canonical name counterpart.</t>
-<t>Capture Statistics Block: it defines how to store some statistical data (e.g. packet dropped, etc) which can be useful to undestand the conditions in which the capture has been made.</t>
-<t>Compression Marker Block: TODO</t>
-<t>Encryption Marker Block: TODO</t>
-<t>Fixed Length Marker Block: TODO</t>
-</list>
-
-<t>The following blocks instead are considered interesting but the authors believe that they deserve more in-depth discussion before being defined:</t>
-<list style="numbers">
-<t>Further Packet Blocks</t>
-<t>Directory Block</t>
-<t>Traffic Statistics and Monitoring Blocks</t>
-<t>Alert and Security Blocks</t>
-</list>
-
-<t>TODO Currently standardized Block Type codes are specified in Appendix 1.</t>
-
-</section>
-
-<section title="Block Hierarchy and Precedence">
-<t>The file must begin with a Section Header Block. However, more than one Section Header Block can be present on the dump, each one covering the data following it till the next one (or the end of file). A Section includes the data delimited by two Section Header Blocks (or by a Section Header Block and the end of the file), including the first Section Header Block.</t>
-<t>In case an application cannot read a Section because of different version number, it must skip everything until the next Section Header Block. Note that, in order to properly skip the blocks until the next section, all blocks must have the fields Type and Length at the beginning. This is a mandatory requirement that must be maintained in future versions of the block format.</t>
-<t><xref target="fssample-SHB"/> shows two valid files: the first has a typical configuration, with a single Section Header that covers the whole file. The second one contains three headers, and is normally the result of file concatenation. An application that understands only version 1.0 of the file format skips the intermediate section and restart processing the packets after the third Section Header.</t>

-<section title="Data format">
-<t>Data contained in each section will always be saved according to the characteristics (little endian / big endian) of the dumping machine. This refers to all fields that are saved as numbers and that span over two or more bytes.</t>
-<t>The approach of having each section saved in the native format of the generating host is more efficient because it avoids translation of data when reading / writing on the host itself, which is the most common case when generating/processing capture dumps.</t>
-<t>TODO Probably we have to specify something more here. Is what we're saying enough to avoid any kind of ambiguity?.</t>

-<t>The Section Header Block does not contain data but it rather identifies a list of blocks (interfaces, packets) that are logically correlated. This block does not contain any reference to the size of the section it is currently delimiting, therefore the reader cannot skip a whole section at once. In case a section must be skipped, the user has to repeatedly skip all the blocks contained within it; this makes the parsing of the file slower but it permits to append several capture dumps at the same file.</t>

-
-<section anchor="sectionidb" title="Interface Description Block (mandatory)">
-<t>The Interface Description Block is mandatory. This block is needed to specify the characteristics of the network interface on which the capture has been made. In order to properly associate the captured data to the corresponding interface, the Interface Description Block must be defined before any other block that uses it; therefore, this block is usually placed immediately after the Section Header Block.</t>
-
-<t>An Interface Description Block is valid only inside the section which it belongs to. The structure of a Interface Description Block is shown in <xref target="formatidb"/>.</t>

-<t>Interface ID: Specifies the interface this packet comes from, and corresponds to the ID of one of the Interface Description Blocks present in this section of the file (see <xref target="formatidb"/>).</t>
-<t>Drops Count: a local drop counter. It specified the number of packets lost (by the interface and the operating system) between this packet and the preceding one. The value xFFFF (in hexadecimal) is reserved for those systems in which this information is not available.</t>
-<t>Timestamp (High): the most significative part of the timestamp. in standard Unix format, i.e. from 1/1/1970.</t>
-<t>Timestamp (Low): the less significative part of the timestamp. The way to interpret this field is specified by the 'ts_accur' option (see <xref target="formatidb"/>) of the Interface Description block referenced by this packet. If the Interface Description block does not contain a 'ts_accur' option, then this field is expressed in microseconds.</t>
-<t>Captured Len: number of bytes captured from the packet (i.e. the length of the Packet Data field). It will be the minimum value among the actual Packet Length and the snapshot length (defined in <xref target="formatidb"/>).</t>
-<t>Packet Len: actual length of the packet when it was transmitted on the network. Can be different from Captured Len if the user wants only a snapshot of the packet.</t>
-<t>Packet Data: the data coming from the network, including link-layer headers. The length of this field is Captured Len. The format of the link-layer headers depends on the LinkType field specified in the Interface Description Block (see <xref target="sectionidb"/>) and it is specified in Appendix XXX (TODO).</t>

-<t>The Simple Packet Block is a lightweight container for storing the packets coming from the network. Its presence is optional.</t>
-<t>A Simple Packet Block is similar to a Packet Block (see <xref target="sectionpb"/>), but it is smaller, simpler to process and contains only a minimal set of information. This block is preferred to the standard Packet Block when performance or space occupation are critical factors, such as in sustained traffic dump applications. A capture file can contain both Packet Blocks and Simple Packet Blocks: for example, a capture tool could switch from Packet Blocks to Simple Packet Blocks when the hardware resources become critical.</t>
-<t>The Simple Packet Block does not contain the Interface ID field. Therefore, it must be assumed that all the Simple Packet Blocks have been captured on the interface previously specified in the Interface Description Block.</t>

-
-<t>The Simple Packet Block does not contain the timestamp because this is one of the most costly operations on PCs. Additionally, there are applications that do not require it; e.g. an Intrusion Detection System is interested in packets, not in their timestamp.</t>

-<section title="Name Resolution Block (optional)">
-<t>The Name Resolution Block is used to support the correlation of numeric addresses (present in the captured packets) and their corresponding canonical names and it is optional. Having the literal names saved in the file, this prevents the need of a name resolution in a delayed time, when the association between names and addresses can be different from the one in use at capture time. Moreover, The Name Resolution Block avoids the need of issuing a lot of DNS requests every time the trace capture is opened, and allows to have name resolution also when reading the capture with a machine not connected to the network.</t>

-<t>The Fixed Length Block is optional. A file can contain an arbitrary number of these blocks. A Fixed Length Block can be used to optimize the access to the file. Its format is shown in <xref target="formatflm"/>.
-A Fixed Length Block stores records with constant size. It contains a set of Blocks (normally Packet Blocks or Simple Packet Blocks), of wihich it specifies the size. Knowing this size a priori helps to scan the file and to load some portions of it without truncating a block, and is particularly useful with cell-based networks like ATM.</t>

-<t>The file format proposed in this document should be very versatile and satisfy a wide range of applications.
-In the simplest case, it can contain a raw dump of the network data, made of a series of Simple Packet Blocks.
-In the most complex case, it can be used as a repository for heterogeneous information.
-In every case, the file remains easy to parse and an application can always skip the data it is not interested in; at the same time, different applications can share the file, and each of them can benfit of the information produced by the others.
-Two or more files can be concatenated obtaining another valid file.</t>

+.SH NAME
+pcap-filter \- packet filter syntax
+.br
+.ad
+.SH DESCRIPTION
+.LP
+.B pcap_compile()
+is used to compile a string into a filter program.
+The resulting filter program can then be applied to
+some stream of packets to determine which packets will be supplied to
+.BR pcap_loop() ,
+.BR pcap_dispatch() ,
+.BR pcap_next() ,
+or
+.BR pcap_next_ex() .
+.LP
+The \fIfilter expression\fP consists of one or more
+.IR primitives .
+Primitives usually consist of an
+.I id
+(name or number) preceded by one or more qualifiers.
+There are three
+different kinds of qualifier:
+.IP \fItype\fP
+qualifiers say what kind of thing the id name or number refers to.
+Possible types are
+.BR host ,
+.B net ,
+.B port
+and
+.BR portrange .
+E.g., `host foo', `net 128.3', `port 20', `portrange 6000-6008'.
+If there is no type
+qualifier,
+.B host
+is assumed.
+.IP \fIdir\fP
+qualifiers specify a particular transfer direction to and/or from
+.IR id .
+Possible directions are
+.BR src ,
+.BR dst ,
+.BR "src or dst" ,
+.BR "src and dst" ,
+.BR addr1 ,
+.BR addr2 ,
+.BR addr3 ,
+and
+.BR addr4 .
+E.g., `src foo', `dst net 128.3', `src or dst port ftp-data'.
+If
+there is no dir qualifier,
+.B "src or dst"
+is assumed.
+The
+.BR addr1 ,
+.BR addr2 ,
+.BR addr3 ,
+and
+.B addr4
+qualifiers are only valid for IEEE 802.11 Wireless LAN link layers.
+For some link layers, such as SLIP and the ``cooked'' Linux capture mode
+used for the ``any'' device and for some other device types, the
+.B inbound
+and
+.B outbound
+qualifiers can be used to specify a desired direction.
+.IP \fIproto\fP
+qualifiers restrict the match to a particular protocol.
+Possible
+protos are:
+.BR ether ,
+.BR fddi ,
+.BR tr ,
+.BR wlan ,
+.BR ip ,
+.BR ip6 ,
+.BR arp ,
+.BR rarp ,
+.BR decnet ,
+.B tcp
+and
+.BR udp .
+E.g., `ether src foo', `arp net 128.3', `tcp port 21', `udp portrange
+7000-7009', `wlan addr2 0:2:3:4:5:6'.
+If there is
+no proto qualifier, all protocols consistent with the type are
+assumed.
+E.g., `src foo' means `(ip or arp or rarp) src foo'
+(except the latter is not legal syntax), `net bar' means `(ip or
+arp or rarp) net bar' and `port 53' means `(tcp or udp) port 53'.
+.LP
+[`fddi' is actually an alias for `ether'; the parser treats them
+identically as meaning ``the data link level used on the specified
+network interface.''  FDDI headers contain Ethernet-like source
+and destination addresses, and often contain Ethernet-like packet
+types, so you can filter on these FDDI fields just as with the
+analogous Ethernet fields.
+FDDI headers also contain other fields,
+but you cannot name them explicitly in a filter expression.
+.LP
+Similarly, `tr' and `wlan' are aliases for `ether'; the previous
+paragraph's statements about FDDI headers also apply to Token Ring
+and 802.11 wireless LAN headers.  For 802.11 headers, the destination
+address is the DA field and the source address is the SA field; the
+BSSID, RA, and TA fields aren't tested.]
+.LP
+In addition to the above, there are some special `primitive' keywords
+that don't follow the pattern:
+.BR gateway ,
+.BR broadcast ,
+.BR less ,
+.B greater
+and arithmetic expressions.
+All of these are described below.
+.LP
+More complex filter expressions are built up by using the words
+.BR and ,
+.B or
+and
+.B not
+to combine primitives.
+E.g., `host foo and not port ftp and not port ftp-data'.
+To save typing, identical qualifier lists can be omitted.
+E.g.,
+`tcp dst port ftp or ftp-data or domain' is exactly the same as
+`tcp dst port ftp or tcp dst port ftp-data or tcp dst port domain'.
+.LP
+Allowable primitives are:
+.IP "\fBdst host \fIhost\fR"
+True if the IPv4/v6 destination field of the packet is \fIhost\fP,
+which may be either an address or a name.
+.IP "\fBsrc host \fIhost\fR"
+True if the IPv4/v6 source field of the packet is \fIhost\fP.
+.IP "\fBhost \fIhost\fP
+True if either the IPv4/v6 source or destination of the packet is \fIhost\fP.
+.IP
+Any of the above host expressions can be prepended with the keywords,
+\fBip\fP, \fBarp\fP, \fBrarp\fP, or \fBip6\fP as in:
+.in +.5i
+.nf
+\fBip host \fIhost\fR
+.fi
+.in -.5i
+which is equivalent to:
+.in +.5i
+.nf
+\fBether proto \fI\\ip\fB and host \fIhost\fR
+.fi
+.in -.5i
+If \fIhost\fR is a name with multiple IP addresses, each address will
+be checked for a match.
+.IP "\fBether dst \fIehost\fP
+True if the Ethernet destination address is \fIehost\fP.
+\fIEhost\fP
+may be either a name from /etc/ethers or a number (see
+.IR ethers (3N)
+for numeric format).
+.IP "\fBether src \fIehost\fP
+True if the Ethernet source address is \fIehost\fP.
+.IP "\fBether host \fIehost\fP
+True if either the Ethernet source or destination address is \fIehost\fP.
+.IP "\fBgateway\fP \fIhost\fP
+True if the packet used \fIhost\fP as a gateway.
+I.e., the Ethernet
+source or destination address was \fIhost\fP but neither the IP source
+nor the IP destination was \fIhost\fP.
+\fIHost\fP must be a name and
+must be found both by the machine's host-name-to-IP-address resolution
+mechanisms (host name file, DNS, NIS, etc.) and by the machine's
+host-name-to-Ethernet-address resolution mechanism (/etc/ethers, etc.).
+(An equivalent expression is
+.in +.5i
+.nf
+\fBether host \fIehost \fBand not host \fIhost\fR
+.fi
+.in -.5i
+which can be used with either names or numbers for \fIhost / ehost\fP.)
+This syntax does not work in IPv6-enabled configuration at this moment.
+.IP "\fBdst net \fInet\fR"
+True if the IPv4/v6 destination address of the packet has a network
+number of \fInet\fP.
+\fINet\fP may be either a name from the networks database
+(/etc/networks, etc.) or a network number.
+An IPv4 network number can be written as a dotted quad (e.g., 192.168.1.0),
+dotted triple (e.g., 192.168.1), dotted pair (e.g, 172.16), or single
+number (e.g., 10); the netmask is 255.255.255.255 for a dotted quad
+(which means that it's really a host match), 255.255.255.0 for a dotted
+triple, 255.255.0.0 for a dotted pair, or 255.0.0.0 for a single number.
+An IPv6 network number must be written out fully; the netmask is
+ff:ff:ff:ff:ff:ff:ff:ff, so IPv6 "network" matches are really always
+host matches, and a network match requires a netmask length.
+.IP "\fBsrc net \fInet\fR"
+True if the IPv4/v6 source address of the packet has a network
+number of \fInet\fP.
+.IP "\fBnet \fInet\fR"
+True if either the IPv4/v6 source or destination address of the packet has a network
+number of \fInet\fP.
+.IP "\fBnet \fInet\fR \fBmask \fInetmask\fR"
+True if the IPv4 address matches \fInet\fR with the specific \fInetmask\fR.
+May be qualified with \fBsrc\fR or \fBdst\fR.
+Note that this syntax is not valid for IPv6 \fInet\fR.
+.IP "\fBnet \fInet\fR/\fIlen\fR"
+True if the IPv4/v6 address matches \fInet\fR with a netmask \fIlen\fR
+bits wide.
+May be qualified with \fBsrc\fR or \fBdst\fR.
+.IP "\fBdst port \fIport\fR"
+True if the packet is ip/tcp, ip/udp, ip6/tcp or ip6/udp and has a
+destination port value of \fIport\fP.
+The \fIport\fP can be a number or a name used in /etc/services (see
+.IR tcp (4P)
+and
+.IR udp (4P)).
+If a name is used, both the port
+number and protocol are checked.
+If a number or ambiguous name is used,
+only the port number is checked (e.g., \fBdst port 513\fR will print both
+tcp/login traffic and udp/who traffic, and \fBport domain\fR will print
+both tcp/domain and udp/domain traffic).
+.IP "\fBsrc port \fIport\fR"
+True if the packet has a source port value of \fIport\fP.
+.IP "\fBport \fIport\fR"
+True if either the source or destination port of the packet is \fIport\fP.
+.IP "\fBdst portrange \fIport1\fB-\fIport2\fR"
+True if the packet is ip/tcp, ip/udp, ip6/tcp or ip6/udp and has a
+destination port value between \fIport1\fP and \fIport2\fP.
+.I port1
+and
+.I port2
+are interpreted in the same fashion as the
+.I port
+parameter for
+.BR port .
+.IP "\fBsrc portrange \fIport1\fB-\fIport2\fR"
+True if the packet has a source port value between \fIport1\fP and
+\fIport2\fP.
+.IP "\fBportrange \fIport1\fB-\fIport2\fR"
+True if either the source or destination port of the packet is between
+\fIport1\fP and \fIport2\fP.
+.IP
+Any of the above port or port range expressions can be prepended with
+the keywords, \fBtcp\fP or \fBudp\fP, as in:
+.in +.5i
+.nf
+\fBtcp src port \fIport\fR
+.fi
+.in -.5i
+which matches only tcp packets whose source port is \fIport\fP.
+.IP "\fBless \fIlength\fR"
+True if the packet has a length less than or equal to \fIlength\fP.
+This is equivalent to:
+.in +.5i
+.nf
+\fBlen <= \fIlength\fP.
+.fi
+.in -.5i
+.IP "\fBgreater \fIlength\fR"
+True if the packet has a length greater than or equal to \fIlength\fP.
+This is equivalent to:
+.in +.5i
+.nf
+\fBlen >= \fIlength\fP.
+.fi
+.in -.5i
+.IP "\fBip proto \fIprotocol\fR"
+True if the packet is an IPv4 packet (see
+.IR ip (4P))
+of protocol type \fIprotocol\fP.
+\fIProtocol\fP can be a number or one of the names
+\fBicmp\fP, \fBicmp6\fP, \fBigmp\fP, \fBigrp\fP, \fBpim\fP, \fBah\fP,
+\fBesp\fP, \fBvrrp\fP, \fBudp\fP, or \fBtcp\fP.
+Note that the identifiers \fBtcp\fP, \fBudp\fP, and \fBicmp\fP are also
+keywords and must be escaped via backslash (\\), which is \\\\ in the C-shell.
+Note that this primitive does not chase the protocol header chain.
+.IP "\fBip6 proto \fIprotocol\fR"
+True if the packet is an IPv6 packet of protocol type \fIprotocol\fP.
+Note that this primitive does not chase the protocol header chain.
+.IP "\fBip6 protochain \fIprotocol\fR"
+True if the packet is IPv6 packet,
+and contains protocol header with type \fIprotocol\fR
+in its protocol header chain.
+For example,
+.in +.5i
+.nf
+\fBip6 protochain 6\fR
+.fi
+.in -.5i
+matches any IPv6 packet with TCP protocol header in the protocol header chain.
+The packet may contain, for example,
+authentication header, routing header, or hop-by-hop option header,
+between IPv6 header and TCP header.
+The BPF code emitted by this primitive is complex and
+cannot be optimized by the BPF optimizer code, so this can be somewhat
+slow.
+.IP "\fBip protochain \fIprotocol\fR"
+Equivalent to \fBip6 protochain \fIprotocol\fR, but this is for IPv4.
+.IP "\fBether broadcast\fR"
+True if the packet is an Ethernet broadcast packet.
+The \fIether\fP
+keyword is optional.
+.IP "\fBip broadcast\fR"
+True if the packet is an IPv4 broadcast packet.
+It checks for both the all-zeroes and all-ones broadcast conventions,
+and looks up the subnet mask on the interface on which the capture is
+being done.
+.IP
+If the subnet mask of the interface on which the capture is being done
+is not available, either because the interface on which capture is being
+done has no netmask or because the capture is being done on the Linux
+"any" interface, which can capture on more than one interface, this
+check will not work correctly.
+.IP "\fBether multicast\fR"
+True if the packet is an Ethernet multicast packet.
+The \fBether\fP
+keyword is optional.
+This is shorthand for `\fBether[0] & 1 != 0\fP'.
+.IP "\fBip multicast\fR"
+True if the packet is an IPv4 multicast packet.
+.IP "\fBip6 multicast\fR"
+True if the packet is an IPv6 multicast packet.
+.IP  "\fBether proto \fIprotocol\fR"
+True if the packet is of ether type \fIprotocol\fR.
+\fIProtocol\fP can be a number or one of the names
+\fBip\fP, \fBip6\fP, \fBarp\fP, \fBrarp\fP, \fBatalk\fP, \fBaarp\fP,
+\fBdecnet\fP, \fBsca\fP, \fBlat\fP, \fBmopdl\fP, \fBmoprc\fP,
+\fBiso\fP, \fBstp\fP, \fBipx\fP, or \fBnetbeui\fP.
+Note these identifiers are also keywords
+and must be escaped via backslash (\\).
+.IP
+[In the case of FDDI (e.g., `\fBfddi protocol arp\fR'), Token Ring
+(e.g., `\fBtr protocol arp\fR'), and IEEE 802.11 wireless LANS (e.g.,
+`\fBwlan protocol arp\fR'), for most of those protocols, the
+protocol identification comes from the 802.2 Logical Link Control (LLC)
+header, which is usually layered on top of the FDDI, Token Ring, or
+802.11 header.
+.IP
+When filtering for most protocol identifiers on FDDI, Token Ring, or
+802.11, the filter checks only the protocol ID field of an LLC header
+in so-called SNAP format with an Organizational Unit Identifier (OUI) of
+0x000000, for encapsulated Ethernet; it doesn't check whether the packet
+is in SNAP format with an OUI of 0x000000.

+True if the relation holds, where \fIrelop\fR is one of >, <, >=, <=, =,

+constants (expressed in standard C syntax), the normal binary operators
+[+, -, *, /, &, |, <<, >>], a length operator, and special packet data
+accessors.  Note that all comparisons are unsigned, so that, for example,
+0x80000000 and 0xffffffff are > 0.
+To access
+data inside the packet, use the following syntax:
+.in +.5i
+.nf
+\fIproto\fB [ \fIexpr\fB : \fIsize\fB ]\fR
+.fi
+.in -.5i
+\fIProto\fR is one of \fBether, fddi, tr, wlan, ppp, slip, link,
+ip, arp, rarp, tcp, udp, icmp, ip6\fR or \fBradio\fR, and
+indicates the protocol layer for the index operation.
+(\fBether, fddi, wlan, tr, ppp, slip\fR and \fBlink\fR all refer to the
+link layer. \fBradio\fR refers to the "radio header" added to some
+802.11 captures.)
+Note that \fItcp, udp\fR and other upper-layer protocol types only
+apply to IPv4, not IPv6 (this will be fixed in the future).
+The byte offset, relative to the indicated protocol layer, is
+given by \fIexpr\fR.
+\fISize\fR is optional and indicates the number of bytes in the
+field of interest; it can be either one, two, or four, and defaults to one.
+The length operator, indicated by the keyword \fBlen\fP, gives the
+length of the packet.
+
+For example, `\fBether[0] & 1 != 0\fP' catches all multicast traffic.
+The expression `\fBip[0] & 0xf != 5\fP'
+catches all IPv4 packets with options.
+The expression
+`\fBip[6:2] & 0x1fff = 0\fP'
+catches only unfragmented IPv4 datagrams and frag zero of fragmented
+IPv4 datagrams.
+This check is implicitly applied to the \fBtcp\fP and \fBudp\fP
+index operations.
+For instance, \fBtcp[0]\fP always means the first
+byte of the TCP \fIheader\fP, and never means the first byte of an
+intervening fragment.
+
+Some offsets and field values may be expressed as names rather than
+as numeric values.
+The following protocol header field offsets are
+available: \fBicmptype\fP (ICMP type field), \fBicmpcode\fP (ICMP
+code field), and \fBtcpflags\fP (TCP flags field).
+
+The following ICMP type field values are available: \fBicmp-echoreply\fP,
+\fBicmp-unreach\fP, \fBicmp-sourcequench\fP, \fBicmp-redirect\fP,
+\fBicmp-echo\fP, \fBicmp-routeradvert\fP, \fBicmp-routersolicit\fP,
+\fBicmp-timxceed\fP, \fBicmp-paramprob\fP, \fBicmp-tstamp\fP,
+\fBicmp-tstampreply\fP, \fBicmp-ireq\fP, \fBicmp-ireqreply\fP,
+\fBicmp-maskreq\fP, \fBicmp-maskreply\fP.
+
+The following TCP flags field values are available: \fBtcp-fin\fP,
+\fBtcp-syn\fP, \fBtcp-rst\fP, \fBtcp-push\fP,
+\fBtcp-ack\fP, \fBtcp-urg\fP.
+.LP
+Primitives may be combined using:
+.IP
+A parenthesized group of primitives and operators
+(parentheses are special to the Shell and must be escaped).
+.IP
+Negation (`\fB!\fP' or `\fBnot\fP').
+.IP
+Concatenation (`\fB&&\fP' or `\fBand\fP').
+.IP
+Alternation (`\fB||\fP' or `\fBor\fP').
+.LP
+Negation has highest precedence.
+Alternation and concatenation have equal precedence and associate
+left to right.
+Note that explicit \fBand\fR tokens, not juxtaposition,
+are now required for concatenation.
+.LP
+If an identifier is given without a keyword, the most recent keyword
+is assumed.

+.SH NAME
+pcap-linktype \- link-layer header types supported by libpcap
+.SH DESCRIPTION
+For a live capture or ``savefile'', libpcap supplies, as the return
+value of the
+.BR pcap_datalink (3PCAP)
+routine, a value that indicates the type of link-layer header at the
+beginning of the packets it provides.  This is not necessarily the type
+of link-layer header that the packets being captured have on the network
+from which they're being captured; for example, packets from an IEEE
+802.11 network might be provided by libpcap with Ethernet headers that
+the network adapter or the network adapter driver generates from the
+802.11 headers.  The names for those values begin with
+.BR DLT_ ,
+so they are sometimes called "DLT_ values".
+.PP
+The values stored in the link-layer header type field in the savefile
+header are, in most but not all cases, the same as the values returned
+by
+.BR pcap_datalink() .
+The names for those values begin with
+.BR LINKTYPE_ .
+.PP
+The link-layer header types supported by libpcap are listed here.  The
+value corresponding to
+.B LINKTYPE_
+names are given; the value corresponding to
+.B DLT_
+values are, in some cases, platform dependent, and are not given;
+applications should check for particular
+.B DLT_
+values by name.
+.RS 5
+.TP 5
+.BR DLT_NULL "; " LINKTYPE_NULL = 0
+BSD loopback encapsulation; the link layer header is a 4-byte field, in
+.I host
+byte order, containing a PF_ value from
+.B socket.h
+for the network-layer protocol of the packet.
+.IP
+Note that ``host byte order'' is the byte order of the machine on which
+the packets are captured, and the PF_ values are for the OS of the
+machine on which the packets are captured; if a live capture is being
+done, ``host byte order'' is the byte order of the machine capturing the
+packets, and the PF_ values are those of the OS of the machine capturing
+the packets, but if a ``savefile'' is being read, the byte order and PF_
+values are
+.I not
+necessarily those of the machine reading the capture file.

+.SH NAME
+pcap-savefile \- libpcap savefile format
+.SH DESCRIPTION
+NOTE: applications and libraries should, if possible, use libpcap to
+read savefiles, rather than having their own code to read savefiles. 
+If, in the future, a new file format is supported by libpcap,
+applications and libraries using libpcap to read savefiles will be able
+to read the new format of savefiles, but applications and libraries
+using their own code to read savefiles will have to be changed to
+support the new file format.
+.PP
+``Savefiles'' read and written by libpcap and applications using libpcap
+start with a per-file header.  The format of the per-file header is:
+.RS
+.TS
+box;
+c s
+c | c
+c s.
+Magic number
+_
+Major version	Minor version
+_
+Time zone offset
+_
+Time stamp accuracy
+_
+Snapshot length
+_
+Link-layer header type
+.TE
+.RE
+.PP
+All fields in the per-file header are in the byte order of the host
+writing the file.  The first field in the per-file header is a 4-byte
+magic number, with the value 0xa1b2c3d4.  The magic number, when read by
+a host with the same byte order as the host that wrote the file, will
+have the value 0xa1b2c3d4, and, when read by a host with the opposite
+byte order as the host that wrote the file, will have the value
+0xd4c3b2a1.  That allows software reading the file to determine whether
+the byte order of the host that wrote the file is the same as the byte
+order of the host on which the file is being read, and thus whether the
+values in the per-file and per-packet headers need to be byte-swapped.
+.PP
+Following this are:
+.IP
+A 2-byte file format major version number; the current version number is
+2.
+.IP
+A 2-byte file format minor version number; the current version number is
+4.
+.IP
+A 4-byte time zone offset; this is always 0.
+.IP
+A 4-byte number giving the accuracy of time stamps in the file; this is
+always 0.
+.IP
+A 4-byte number giving the "snapshot length" of the capture; packets
+longer than the snapshot length are truncated to the snapshot length, so
+that, if the snapshot length is
+.IR N ,
+only the first
+.I N
+bytes of a packet longer than
+.I N
+bytes will be saved in the capture.
+.IP
+a 4-byte number giving the link-layer header type for packets in the
+capture; see
+.BR pcap-linktype (@MAN_MISC_INFO@)
+for the
+.B LINKTYPE_
+values that can appear in this field.
+.PP
+Following the per-file header are zero or more packets; each packet
+begins with a per-packet header, which is immediately followed by the
+raw packet data.  The format of the per-packet header is:
+.RS
+.TS
+box;
+c.
+Time stamp, seconds value
+_
+Time stamp, microseconds value
+_
+Length of captured packet data
+_
+Un-truncated length of the packet data
+.TE
+.RE
+.PP
+All fields in the per-packet header are in the byte order of the host
+writing the file.  The per-packet header begins with a time stamp giving
+the approximate time the packet was captured; the time stamp consists of
+a 4-byte value, giving the time in seconds since January 1, 1970,
+00:00:00 UTC, followed by a 4-byte value, giving the time in
+microseconds since that second.  Following that are a 4-byte value
+giving the number of bytes of captured data that follow the per-packet
+header and a 4-byte value giving the number of bytes that would have
+been present had the packet not been truncated by the snapshot length. 
+The two lengths will be equal if the number of bytes of packet data are
+less than or equal to the snapshot length.

+	<P>
+	The ACN provides a customized/distributed version of this library that alows SMPs to
+	interact with the various IOPs within the site providing a standard mechanism
+	to capture LAN and WAN message traffic.

+	<P>
+	Each IOP will be capable of supporting multiple connections from an SMP
+	enabling monitoring of more than one interface at a time, each through
+	its own seperate connection.  The IOP is responsible to ensure and report
+	an error if any attempt is made to monitor the same interface more than once.
+	<P>
+	There are three applications that will be supported by the ACN version of libpcap.
+	They each use a slightly different mode for looping/capturing and termination
+	as summarized in the following table:
+	<P>

+	<P>
+	<B>Note: </B>In all cases, the termination of capturing is always (apparently) followed by
+	pcap_close().  Pcap_breakloop() is only used to stop/suspend looping/processing,
+	and upon close interpretation of the function definitions, it is possible to resume
+	capturing following a pcap_breakloop() without any re-initialization.

-.SH DESCRIPTION
-The Packet Capture library
-provides a high level interface to packet capture systems. All packets
-on the network, even those destined for other hosts, are accessible
-through this mechanism.
-.PP
-.SH ROUTINES
-NOTE:
-.I errbuf
-in
-.BR pcap_open_live() ,
-.BR pcap_open_dead() ,
-.BR pcap_open_offline() ,
-.BR pcap_fopen_offline() ,
-.BR pcap_setnonblock() ,
-.BR pcap_getnonblock() ,
-.BR pcap_findalldevs() ,
-.BR pcap_lookupdev() ,
-and
-.B pcap_lookupnet()
-is assumed to be able to hold at least
-.B PCAP_ERRBUF_SIZE
-chars.
-.PP
-.B pcap_open_live()
-is used to obtain a packet capture descriptor to look
-at packets on the network.
-.I device
-is a string that specifies the network device to open; on Linux systems
-with 2.2 or later kernels, a
-.I device
-argument of "any" or
-.B NULL
-can be used to capture packets from all interfaces.
-.I snaplen
-specifies the maximum number of bytes to capture.  If this value is less
-than the size of a packet that is captured, only the first
-.I snaplen
-bytes of that packet will be captured and provided as packet data.  A
-value of 65535 should be sufficient, on most if not all networks, to
-capture all the data available from the packet.
-.I promisc
-specifies if the interface is to be put into promiscuous mode.
-(Note that even if this parameter is false, the interface
-could well be in promiscuous mode for some other reason.)  For now, this
-doesn't work on the "any" device; if an argument of "any" or NULL is
-supplied, the
-.I promisc
-flag is ignored.
-.I to_ms
-specifies the read timeout in milliseconds.  The read timeout is used to
-arrange that the read not necessarily return immediately when a packet
-is seen, but that it wait for some amount of time to allow more packets
-to arrive and to read multiple packets from the OS kernel in one
-operation.  Not all platforms support a read timeout; on platforms that
-don't, the read timeout is ignored.  A zero value for
-.IR to_ms ,
-on platforms that support a read timeout,
-will cause a read to wait forever to allow enough packets to
-arrive, with no timeout.
-.I errbuf
-is used to return error or warning text.  It will be set to error text when
-.B pcap_open_live()
-fails and returns
-.BR NULL .
-.I errbuf
-may also be set to warning text when
-.B pcap_open_live()
-succeds; to detect this case the caller should store a zero-length string in
-.I errbuf
-before calling
-.B pcap_open_live()
-and display the warning to the user if
-.I errbuf
-is no longer a zero-length string.
-.PP
-.B pcap_open_dead()
-is used for creating a
-.B pcap_t
-structure to use when calling the other functions in libpcap.  It is
-typically used when just using libpcap for compiling BPF code.
-.PP
-.B pcap_open_offline()
-is called to open a ``savefile'' for reading.
-.I fname
-specifies the name of the file to open. The file has
-the same format as those used by
-.B tcpdump(1)
-and
-.BR tcpslice(1) .
-The name "-" in a synonym for
-.BR stdin .
-Alternatively, you may call
-.B pcap_fopen_offline()
-to read dumped data from an existing open stream
-.IR fp .
-Note that on Windows, that stream should be opened in binary mode.
-.I errbuf
-is used to return error text and is only set when
-.B pcap_open_offline()
-or
-.B pcap_fopen_offline()
-fails and returns
-.BR NULL .
-.PP
-.B pcap_dump_open()
-is called to open a ``savefile'' for writing. The name "-" in a synonym
-for
-.BR stdout .
-.B NULL
-is returned on failure.
-.I p
-is a
-.I pcap
-struct as returned by
-.B pcap_open_offline()
-or
-.BR pcap_open_live() .
-.I fname
-specifies the name of the file to open. Alternatively, you may call
-.B pcap_dump_fopen()
-to write data to an existing open stream
-.IR fp .
-Note that on Windows, that stream should be opened in binary mode.
-If
-.B NULL
-is returned,
-.B pcap_geterr()
-can be used to get the error text.
-.PP
-.PP
-.B pcap_setnonblock()
-puts a capture descriptor, opened with
-.BR pcap_open_live() ,
-into ``non-blocking'' mode, or takes it out of ``non-blocking'' mode,
-depending on whether the
-.I nonblock
-argument is non-zero or zero.  It has no effect on ``savefiles''.
-If there is an error, \-1 is returned and
-.I errbuf
-is filled in with an appropriate error message; otherwise, 0 is
-returned.
-In
-``non-blocking'' mode, an attempt to read from the capture descriptor
-with
-.B pcap_dispatch()
-will, if no packets are currently available to be read, return 0
-immediately rather than blocking waiting for packets to arrive.
-.B pcap_loop()
-and
-.B pcap_next()
-will not work in ``non-blocking'' mode.
-.PP
-.B pcap_getnonblock()
-returns the current ``non-blocking'' state of the capture descriptor; it
-always returns 0 on ``savefiles''.
-If there is an error, \-1 is returned and
-.I errbuf
-is filled in with an appropriate error message.
-.PP
-.B pcap_findalldevs()
-constructs a list of network devices that can be opened with
-.BR pcap_open_live() .
-(Note that there may be network devices that cannot be opened with
-.BR pcap_open_live()
-by the
-process calling
-.BR pcap_findalldevs() ,
-because, for example, that process might not have sufficient privileges
-to open them for capturing; if so, those devices will not appear on the
-list.)
-.I alldevsp
-is set to point to the first element of the list; each element of the
-list is of type
-.BR pcap_if_t ,
-and has the following members:
-.RS
-.TP
-.B next
-if not
-.BR NULL ,
-a pointer to the next element in the list;
-.B NULL
-for the last element of the list
-.TP
-.B name
-a pointer to a string giving a name for the device to pass to
-.B pcap_open_live()
-.TP
-.B description
-if not
-.BR NULL ,
-a pointer to a string giving a human-readable description of the device
-.TP
-.B addresses
-a pointer to the first element of a list of addresses for the interface
-.TP
-.B flags
-interface flags:
-.RS
-.TP
-.B PCAP_IF_LOOPBACK
-set if the interface is a loopback interface
-.RE
-.RE
-.PP
-Each element of the list of addresses is of type
-.BR pcap_addr_t ,
-and has the following members:
-.RS
-.TP
-.B next
-if not
-.BR NULL ,
-a pointer to the next element in the list;
-.B NULL
-for the last element of the list
-.TP
-.B addr
-a pointer to a
-.B "struct sockaddr"
-containing an address
-.TP
-.B netmask
-if not
-.BR NULL ,
-a pointer to a
-.B "struct sockaddr"
-that contains the netmask corresponding to the address pointed to by
-.B addr
-.TP
-.B broadaddr
-if not
-.BR NULL ,
-a pointer to a
-.B "struct sockaddr"
-that contains the broadcast address corresponding to the address pointed
-to by
-.BR addr ;
-may be null if the interface doesn't support broadcasts
-.TP
-.B dstaddr
-if not
-.BR NULL ,
-a pointer to a
-.B "struct sockaddr"
-that contains the destination address corresponding to the address pointed
-to by
-.BR addr ;
-may be null if the interface isn't a point-to-point interface
-.RE
-.PP
-Note that not all the addresses in the list of addresses are
-necessarily IPv4 or IPv6 addresses - you must check the
-.B sa_family
-member of the
-.B "struct sockaddr"
-before interpreting the contents of the address.
-.PP
-.B \-1
-is returned on failure, in which case
-.B errbuf
-is filled in with an appropriate error message;
-.B 0
-is returned on success.
-.PP
-.B pcap_freealldevs()
-is used to free a list allocated by
-.BR pcap_findalldevs() .
-.PP
-.B pcap_lookupdev()
-returns a pointer to a network device suitable for use with
-.B pcap_open_live()
-and
-.BR pcap_lookupnet() .
-If there is an error,
-.B NULL
-is returned and
-.I errbuf
-is filled in with an appropriate error message.
-.PP
-.B pcap_lookupnet()
-is used to determine the network number and mask
-associated with the network device
-.BR device .
-Both
-.I netp
-and
-.I maskp
-are
-.I bpf_u_int32
-pointers.
-A return of \-1 indicates an error in which case
-.I errbuf
-is filled in with an appropriate error message.
-.PP
-.B pcap_dispatch()
-is used to collect and process packets.
-.I cnt
-specifies the maximum number of packets to process before returning.
-This is not a minimum number; when reading a live capture, only one
-bufferful of packets is read at a time, so fewer than
-.I cnt
-packets may be processed. A
-.I cnt
-of \-1 processes all the packets received in one buffer when reading a
-live capture, or all the packets in the file when reading a
-``savefile''.
-.I callback
-specifies a routine to be called with three arguments:
-a
-.I u_char
-pointer which is passed in from
-.BR pcap_dispatch() ,
-a
-.I const struct pcap_pkthdr
-pointer to a structure with the following members:
-.RS
-.TP
-.B ts
-a
-.I struct timeval
-containing the time when the packet was captured
-.TP
-.B caplen
-a
-.I bpf_u_int32
-giving the number of bytes of the packet that are available from the
-capture
-.TP
-.B len
-a
-.I bpf_u_int32
-giving the length of the packet, in bytes (which might be more than the
-number of bytes available from the capture, if the length of the packet
-is larger than the maximum number of bytes to capture)
-.RE
-.PP
-and a
-.I const u_char
-pointer to the first
-.B caplen
-(as given in the
-.I struct pcap_pkthdr
-a pointer to which is passed to the callback routine)
-bytes of data from the packet (which won't necessarily be the entire
-packet; to capture the entire packet, you will have to provide a value
-for
-.I snaplen
-in your call to
-.B pcap_open_live()
-that is sufficiently large to get all of the packet's data - a value of
-65535 should be sufficient on most if not all networks).
-.PP
-The number of packets read is returned.
-0 is returned if no packets were read from a live capture (if, for
-example, they were discarded because they didn't pass the packet filter,
-or if, on platforms that support a read timeout that starts before any
-packets arrive, the timeout expires before any packets arrive, or if the
-file descriptor for the capture device is in non-blocking mode and no
-packets were available to be read) or if no more packets are available
-in a ``savefile.'' A return of \-1 indicates
-an error in which case
-.B pcap_perror()
-or
-.B pcap_geterr()
-may be used to display the error text.
-A return of \-2 indicates that the loop terminated due to a call to
-.B pcap_breakloop()
-before any packets were processed.
-.ft B
-If your application uses pcap_breakloop(),
-make sure that you explicitly check for \-1 and \-2, rather than just
-checking for a return value < 0.
-.ft R
-.PP
-.BR NOTE :
-when reading a live capture,
-.B pcap_dispatch()
-will not necessarily return when the read times out; on some platforms,
-the read timeout isn't supported, and, on other platforms, the timer
-doesn't start until at least one packet arrives.  This means that the
-read timeout should
-.B NOT
-be used in, for example, an interactive application, to allow the packet
-capture loop to ``poll'' for user input periodically, as there's no
-guarantee that
-.B pcap_dispatch()
-will return after the timeout expires.
-.PP
-.B pcap_loop()
-is similar to
-.B pcap_dispatch()
-except it keeps reading packets until
-.I cnt
-packets are processed or an error occurs.
-It does
-.B not
-return when live read timeouts occur.
-Rather, specifying a non-zero read timeout to
-.B pcap_open_live()
-and then calling
-.B pcap_dispatch()
-allows the reception and processing of any packets that arrive when the
-timeout occurs.
-A negative
-.I cnt
-causes
-.B pcap_loop()
-to loop forever (or at least until an error occurs).  \-1 is returned on
-an error; 0 is returned if
-.I cnt
-is exhausted; \-2 is returned if the loop terminated due to a call to
-.B pcap_breakloop()
-before any packets were processed.
-.ft B
-If your application uses pcap_breakloop(),
-make sure that you explicitly check for \-1 and \-2, rather than just
-checking for a return value < 0.
-.ft R
-.PP
-.B pcap_next()
-reads the next packet (by calling
-.B pcap_dispatch()
-with a
-.I cnt
-of 1) and returns a
-.I u_char
-pointer to the data in that packet.  (The
-.I pcap_pkthdr
-struct for that packet is not supplied.)
-.B NULL
-is returned if an error occured, or if no packets were read from a live
-capture (if, for example, they were discarded because they didn't pass
-the packet filter, or if, on platforms that support a read timeout that
-starts before any packets arrive, the timeout expires before any packets
-arrive, or if the file descriptor for the capture device is in
-non-blocking mode and no packets were available to be read), or if no
-more packets are available in a ``savefile.''  Unfortunately, there is
-no way to determine whether an error occured or not.
-.PP
-.B pcap_next_ex()
-reads the next packet and returns a success/failure indication:
-.RS
-.TP
-1
-the packet was read without problems
-.TP
-0
-packets are being read from a live capture, and the timeout expired
-.TP
-\-1
-an error occurred while reading the packet
-.TP
-\-2
-packets are being read from a ``savefile'', and there are no more
-packets to read from the savefile.
-.RE
-.PP
-If the packet was read without problems, the pointer pointed to by the
-.I pkt_header
-argument is set to point to the
-.I pcap_pkthdr
-struct for the packet, and the
-pointer pointed to by the
-.I pkt_data
-argument is set to point to the data in the packet.
-.PP
-.B pcap_breakloop()
-sets a flag that will force
-.B pcap_dispatch()
-or
-.B pcap_loop()
-to return rather than looping; they will return the number of packets
-that have been processed so far, or \-2 if no packets have been
-processed so far.
-.PP
-This routine is safe to use inside a signal handler on UNIX or a console
-control handler on Windows, as it merely sets a flag that is checked
-within the loop.
-.PP
-The flag is checked in loops reading packets from the OS - a signal by
-itself will not necessarily terminate those loops - as well as in loops
-processing a set of packets returned by the OS.
-.ft B
-Note that if you are catching signals on UNIX systems that support
-restarting system calls after a signal, and calling pcap_breakloop()
-in the signal handler, you must specify, when catching those signals,
-that system calls should NOT be restarted by that signal.  Otherwise,
-if the signal interrupted a call reading packets in a live capture,
-when your signal handler returns after calling pcap_breakloop(), the
-call will be restarted, and the loop will not terminate until more
-packets arrive and the call completes.
-.PP
-Note also that, in a multi-threaded application, if one thread is
-blocked in
-.BR pcap_dispatch() ,
-.BR pcap_loop() ,
-.BR pcap_next() ,
-or
-.BR pcap_next_ex() ,
-a call to
-.B pcap_breakloop()
-in a different thread will not unblock that thread; you will need to use
-whatever mechanism the OS provides for breaking a thread out of blocking
-calls in order to unblock the thread, such as thread cancellation in
-systems that support POSIX threads.
-.ft R
-.PP
-Note that
-.B pcap_next()
-will, on some platforms, loop reading packets from the OS; that loop
-will not necessarily be terminated by a signal, so
-.B pcap_breakloop()
-should be used to terminate packet processing even if
-.B pcap_next()
-is being used.
-.PP
-.B pcap_breakloop()
-does not guarantee that no further packets will be processed by
-.B pcap_dispatch()
-or
-.B pcap_loop()
-after it is called; at most one more packet might be processed.
-.PP
-If \-2 is returned from
-.B pcap_dispatch()
-or
-.BR pcap_loop() ,
-the flag is cleared, so a subsequent call will resume reading packets. 
-If a positive number is returned, the flag is not cleared, so a
-subsequent call will return \-2 and clear the flag.
-.PP
-.B pcap_inject()
-sends a raw packet through the network interface;
-.I buf
-points to the data of the packet, including the link-layer header, and
-.I size
-is the number of bytes in the packet.
-It returns the number of bytes written on success.  A return of \-1
-indicates an error in which case
-.B pcap_perror()
-or
-.B pcap_geterr()
-may be used to display the error text.
-Note that, even if you successfully open the network interface, you
-might not have permission to send packets on it, or it might not support
-sending packets; as
-.I pcap_open_live()
-doesn't have a flag to indicate whether to open for capturing, sending,
-or capturing and sending, you cannot request an open that supports
-sending and be notified at open time whether sending will be possible.
-Note also that some devices might not support sending packets.
-.PP
-Note that, on some platforms, the link-layer header of the packet that's
-sent might not be the same as the link-layer header of the packet
-supplied to
-.BR pcap_inject() ,
-as the source link-layer address, if the header contains such an
-address, might be changed to be the address assigned to the interface on
-which the packet it sent, if the platform doesn't support sending
-completely raw and unchanged packets.  Even worse, some drivers on some
-platforms might change the link-layer type field to whatever value
-libpcap used when attaching to the device, even on platforms that
-.I do
-nominally support sending completely raw and unchanged packets.
-.PP
-.B pcap_sendpacket()
-is like
-.BR pcap_inject() ,
-but it returns 0 on success and \-1 on failure.
-.RB ( pcap_inject()
-comes from OpenBSD;
-.B pcap_sendpacket()
-comes from WinPcap.  Both are provided for compatibility.)
-.PP
-.B pcap_dump()
-outputs a packet to the ``savefile'' opened with
-.BR pcap_dump_open() .
-Note that its calling arguments are suitable for use with
-.B pcap_dispatch()
-or
-.BR pcap_loop() .
-If called directly, the 
-.I user
-parameter is of type 
-.I pcap_dumper_t
-as returned by
-.BR pcap_dump_open() .
-.PP
-.B pcap_compile()
-is used to compile the string
-.I str
-into a filter program.
-.I program
-is a pointer to a
-.I bpf_program
-struct and is filled in by
-.BR pcap_compile() .
-.I optimize
-controls whether optimization on the resulting code is performed.
-.I netmask
-specifies the IPv4 netmask of the network on which packets are being
-captured; it is used only when checking for IPv4 broadcast addresses in
-the filter program.  If the netmask of the network on which packets are
-being captured isn't known to the program, or if packets are being
-captured on the Linux "any" pseudo-interface that can capture on more
-than one network, a value of 0 can be supplied; tests for IPv4 broadcast
-addreses won't be done correctly, but all other tests in the filter
-program will be OK.  A return of \-1 indicates an error in which case
-.BR pcap_geterr()
-may be used to display the error text.
-.PP
-.B pcap_compile_nopcap()
-is similar to
-.B pcap_compile()
-except that instead of passing a pcap structure, one passes the
-snaplen and linktype explicitly.  It is intended to be used for
-compiling filters for direct BPF usage, without necessarily having
-called
-.BR pcap_open() .
-A return of \-1 indicates an error; the error text is unavailable.
-.RB ( pcap_compile_nopcap()
-is a wrapper around
-.BR pcap_open_dead() ,
-.BR pcap_compile() ,
-and
-.BR pcap_close() ;
-the latter three routines can be used directly in order to get the error
-text for a compilation error.)
-.B
-.PP
-.B pcap_setfilter()
-is used to specify a filter program.
-.I fp
-is a pointer to a
-.I bpf_program
-struct, usually the result of a call to
-.BR pcap_compile() .
-.B \-1
-is returned on failure, in which case
-.BR pcap_geterr()
-may be used to display the error text;
-.B 0
-is returned on success.
-.PP
-.B pcap_freecode()
-is used to free up allocated memory pointed to by a
-.I bpf_program
-struct generated by
-.B pcap_compile()
-when that BPF program is no longer needed, for example after it
-has been made the filter program for a pcap structure by a call to
-.BR pcap_setfilter() .
-.PP
-.B pcap_setdirection()
-is used to specify a direction that packets will be captured.
-.I pcap_direction_t 
-is one of the constants
-.BR PCAP_D_IN ,
-.B PCAP_D_OUT
-or 
-.BR PCAP_D_INOUT .
-.B PCAP_D_IN
-will only capture packets received by the device,
-.B PCAP_D_OUT
-will only capture packets sent by the device and
-.B PCAP_D_INOUT
-will capture packets received by or sent by the device.
-.B PCAP_D_INOUT
-is the default setting if this function is not called.  This isn't
-necessarily supported on all platforms; some platforms might return an
-error, and some other platforms might not support
-.BR PCAP_D_OUT .
-This operation is not supported if a ``savefile'' is being read.
-.B \-1
-is returned on failure,
-.B 0
-is returned on success.
-.PP
-.B pcap_datalink()
-returns the link layer type; link layer types it can return include:
-.PP
-.RS 5
-.TP 5
-.B DLT_NULL
-BSD loopback encapsulation; the link layer header is a 4-byte field, in
-.I host
-byte order, containing a PF_ value from
-.B socket.h
-for the network-layer protocol of the packet.
-.IP
-Note that ``host byte order'' is the byte order of the machine on which
-the packets are captured, and the PF_ values are for the OS of the
-machine on which the packets are captured; if a live capture is being
-done, ``host byte order'' is the byte order of the machine capturing the
-packets, and the PF_ values are those of the OS of the machine capturing
-the packets, but if a ``savefile'' is being read, the byte order and PF_
-values are
-.I not
-necessarily those of the machine reading the capture file.
-.TP 5
-.B DLT_EN10MB
-Ethernet (10Mb, 100Mb, 1000Mb, and up)
-.TP 5
-.B DLT_IEEE802
-IEEE 802.5 Token Ring
-.TP 5
-.B DLT_ARCNET
-ARCNET
-.TP 5
-.B DLT_SLIP
-SLIP; the link layer header contains, in order:
-.RS 10
-.LP
-a 1-byte flag, which is 0 for packets received by the machine and 1 for
-packets sent by the machine;
-.LP
-a 1-byte field, the upper 4 bits of which indicate the type of packet,
-as per RFC 1144:
-.RS 5
-.TP 5
-0x40
-an unmodified IP datagram (TYPE_IP);
-.TP 5
-0x70
-an uncompressed-TCP IP datagram (UNCOMPRESSED_TCP), with that byte being
-the first byte of the raw IP header on the wire, containing the
-connection number in the protocol field;
-.TP 5
-0x80
-a compressed-TCP IP datagram (COMPRESSED_TCP), with that byte being the
-first byte of the compressed TCP/IP datagram header;
-.RE
-.LP
-for UNCOMPRESSED_TCP, the rest of the modified IP header, and for
-COMPRESSED_TCP, the compressed TCP/IP datagram header;
-.RE
-.RS 5
-.LP
-for a total of 16 bytes; the uncompressed IP datagram follows the header.
-.RE
-.TP 5
-.B DLT_PPP
-PPP; if the first 2 bytes are 0xff and 0x03, it's PPP in HDLC-like
-framing, with the PPP header following those two bytes, otherwise it's
-PPP without framing, and the packet begins with the PPP header.
-.TP 5
-.B DLT_FDDI
-FDDI
-.TP 5
-.B DLT_ATM_RFC1483
-RFC 1483 LLC/SNAP-encapsulated ATM; the packet begins with an IEEE 802.2
-LLC header.
-.TP 5
-.B DLT_RAW
-raw IP; the packet begins with an IP header.
-.TP 5
-.B DLT_PPP_SERIAL
-PPP in HDLC-like framing, as per RFC 1662, or Cisco PPP with HDLC
-framing, as per section 4.3.1 of RFC 1547; the first byte will be 0xFF
-for PPP in HDLC-like framing, and will be 0x0F or 0x8F for Cisco PPP
-with HDLC framing.
-.TP 5
-.B DLT_PPP_ETHER
-PPPoE; the packet begins with a PPPoE header, as per RFC 2516.
-.TP 5
-.B DLT_C_HDLC
-Cisco PPP with HDLC framing, as per section 4.3.1 of RFC 1547.
-.TP 5
-.B DLT_IEEE802_11

+.SH NAME
+pcap \- Packet Capture library
+.SH SYNOPSIS
+.nf
+.ft B
+#include <pcap/pcap.h>
+.LP
+.ft B
+.ft
+.fi
+.SH DESCRIPTION
+The Packet Capture library
+provides a high level interface to packet capture systems. All packets
+on the network, even those destined for other hosts, are accessible
+through this mechanism.
+It also supports saving captured packets to a ``savefile'', and reading
+packets from a ``savefile''.
+.PP
+To open a handle for a live capture, call
+.BR pcap_create() ,
+set the appropriate options on the handle, and then activate it with
+.BR pcap_activate() .
+To open a handle for a ``savefile'' with captured packets, call
+.BR pcap_open_offline() .
+Both
+.B pcap_create()
+and
+.B pcap_open_offline()
+return a pointer to a
+.BR pcap_t ,
+which is the handle used for reading packets from the capture stream or
+the ``savefile'', and for finding out information about the capture
+stream or ``savefile''.
+.PP
+The options that can be set on a capture handle include
+.IP "snapshot length"
+If, when capturing, you capture the entire contents of the packet, that
+requires more CPU time to copy the packet to your application, more disk
+and possibly network bandwidth to write the packet data to a file, and
+more disk space to save the packet.  If you don't need the entire
+contents of the packet - for example, if you are only interested in the
+TCP headers of packets - you can set the "snapshot length" for the
+capture to an appropriate value.  If the snapshot length is set to
+.IR snaplen ,
+and
+.I snaplen
+is less
+than the size of a packet that is captured, only the first
+.I snaplen
+bytes of that packet will be captured and provided as packet data.
+.IP
+A snapshot length of 65535 should be sufficient, on most if not all
+networks, to capture all the data available from the packet.
+.IP
+The snapshot length is set with
+.BR pcap_set_snaplen() .
+.IP "promiscuous mode"
+On broadcast LANs such as Ethernet, if the network isn't switched, or if
+the adapter is connected to a "mirror port" on a switch to which all
+packets passing through the switch are sent, a network adapter receives
+all packets on the LAN, including unicast or multicast packets not sent
+to a network address that the network adapter isn't configured to
+recognize.
+.IP
+Normally, the adapter will discard those packets; however, many network
+adapters support "promiscuous mode", which is a mode in which all
+packets, even if they are not sent to an address that the adapter
+recognizes, are provided to the host.  This is useful for passively
+capturing traffic between two or more other hosts for analysis.
+.IP
+Note that even if an application does not set promiscuous mode, the
+adapter could well be in promiscuous mode for some other reason.
+.IP
+For now, this doesn't work on the "any" device; if an argument of "any"
+or NULL is supplied, the setting of promiscuous mode is ignored.
+.IP
+Promiscuous mode is set with
+.BR pcap_set_promisc() .
+.IP "monitor mode"
+On IEEE 802.11 wireless LANs, even if an adapter is in promiscuous mode,
+it will supply to the host only frames for the network with which it's
+associated.  It might also supply only data frames, not management or
+control frames, and might not provide the 802.11 header or radio
+information pseudo-header for those frames.
+.IP
+In "monitor mode", sometimes also called "rfmon mode" (for "Radio
+Frequency MONitor"), the adapter will supply all frames that it
+receives, with 802.11 headers, and might supply a pseudo-header with
+radio information about the frame as well.
+.IP
+Note that in monitor mode the adapter might disassociate from the
+network with which it's associated, so that you will not be able to use
+any wireless networks with that adapter.  This could prevent accessing
+files on a network server, or resolving host names or network addresses,
+if you are capturing in monitor mode and are not connected to another
+network with another adapter.
+.IP
+Monitor mode is set with
+.BR pcap_set_rfmon() ,
+and
+.B pcap_can_set_rfmon()
+can be used to determine whether an adapter can be put into monitor
+mode.
+.IP "read timeout"
+If, when capturing, packets are delivered as soon as they arrive, the
+application capturing the packets will be woken up for each packet as it
+arrives, and might have to make one or more calls to the operating
+system to fetch each packet.
+.IP
+If, instead, packets are not delivered as soon as they arrive, but are
+delivered after a short delay (called a "read timeout"), more than one
+packet can be accumulated before the packets are delivered, so that a
+single wakeup would be done for multiple packets, and each set of calls
+made to the operating system would supply multiple packets, rather than
+a single packet.  This reduces the per-packet CPU overhead if packets
+are arriving at a high rate, increasing the number of packets per second
+that can be captured.
+.IP
+The read timeout is required so that an application won't wait for the
+operating system's capture buffer to fill up before packets are
+delivered; if packets are arriving slowly, that wait could take an
+arbitrarily long period of time.
+.IP
+Not all platforms support a read timeout; on platforms that
+don't, the read timeout is ignored.  A zero value for the timeout,
+on platforms that support a read timeout,
+will cause a read to wait forever to allow enough packets to
+arrive, with no timeout.
+.IP
+.BR NOTE :
+the read timeout cannot be used to cause calls that read
+packets to return within a limited period of time, because, on some
+platforms, the read timeout isn't supported, and, on other platforms,
+the timer doesn't start until at least one packet arrives.  This means
+that the read timeout should
+.B NOT
+be used, for example, in an interactive application to allow the packet
+capture loop to ``poll'' for user input periodically, as there's no
+guarantee that a call reading packets will return after the timeout
+expires even if no packets have arrived.
+.IP
+The read timeout is set with
+.BR pcap_set_timeout() .
+.IP "buffer size"
+Packets that arrive for a capture are stored in a buffer, so that they
+do not have to be read by the application as soon as they arrive.  On
+some platforms, the buffer's size can be set; a size that's too small
+could mean that, if too many packets are being captured and the snapshot
+length doesn't limit the amount of data that's buffered, packets could
+be dropped if the buffer fills up before the application can read
+packets from it, while a size that's too large could use more
+non-pageable operating system memory than is necessary to prevent
+packets from being dropped.
+.IP
+The buffer size is set with
+.BR pcap_set_buffer_size() .
+.PP
+Reading packets from a network interface may require that you have
+special privileges:
+.TP
+.B Under SunOS 3.x or 4.x with NIT or BPF:
+You must have read access to
+.I /dev/nit
+or
+.IR /dev/bpf* .
+.TP
+.B Under Solaris with DLPI:
+You must have read/write access to the network pseudo device, e.g.
+.IR /dev/le .
+On at least some versions of Solaris, however, this is not sufficient to
+allow
+.I tcpdump
+to capture in promiscuous mode; on those versions of Solaris, you must
+be root, or the application capturing packets
+must be installed setuid to root, in order to capture in promiscuous
+mode.  Note that, on many (perhaps all) interfaces, if you don't capture
+in promiscuous mode, you will not see any outgoing packets, so a capture
+not done in promiscuous mode may not be very useful.
+.IP
+In newer versions of Solaris, you must have been given the
+.B net_rawaccess
+privilege; this is both necessary and sufficient to give you access to the
+network pseudo-device - there is no need to change the privileges on
+that device.  A user can be given that privilege by, for example, adding
+that privilege to the user's
+.B defaultpriv
+key with the
+.B usermod (1M)
+command.
+.TP
+.B Under HP-UX with DLPI:
+You must be root or the application capturing packets must be installed
+setuid to root.
+.TP
+.B Under IRIX with snoop:
+You must be root or the application capturing packets must be installed
+setuid to root.
+.TP
+.B Under Linux:
+You must be root or the application capturing packets must be installed
+setuid to root (unless your distribution has a kernel
+that supports capability bits such as CAP_NET_RAW and code to allow
+those capability bits to be given to particular accounts and to cause
+those bits to be set on a user's initial processes when they log in, in
+which case you  must have CAP_NET_RAW in order to capture and
+CAP_NET_ADMIN to enumerate network devices with, for example, the
+.B \-D
+flag).
+.TP
+.B Under ULTRIX and Digital UNIX/Tru64 UNIX:
+Any user may capture network traffic.
+However, no user (not even the super-user) can capture in promiscuous
+mode on an interface unless the super-user has enabled promiscuous-mode
+operation on that interface using
+.IR pfconfig (8),
+and no user (not even the super-user) can capture unicast traffic
+received by or sent by the machine on an interface unless the super-user
+has enabled copy-all-mode operation on that interface using
+.IR pfconfig ,
+so
+.I useful
+packet capture on an interface probably requires that either
+promiscuous-mode or copy-all-mode operation, or both modes of
+operation, be enabled on that interface.
+.TP
+.B Under BSD (this includes Mac OS X):
+You must have read access to
+.I /dev/bpf*
+on systems that don't have a cloning BPF device, or to
+.I /dev/bpf
+on systems that do.
+On BSDs with a devfs (this includes Mac OS X), this might involve more
+than just having somebody with super-user access setting the ownership
+or permissions on the BPF devices - it might involve configuring devfs
+to set the ownership or permissions every time the system is booted,
+if the system even supports that; if it doesn't support that, you might
+have to find some other way to make that happen at boot time.
+.PP
+Reading a saved packet file doesn't require special privileges.
+.PP
+To open a ``savefile`` to which to write packets, call
+.BR pcap_dump_open() .
+It returns a pointer to a
+.BR pcap_dumper_t ,
+which is the handle used for writing packets to the ``savefile''.
+.PP
+Packets are read with
+.B pcap_dispatch()
+or
+.BR pcap_loop() ,
+which process one or more packets, calling a callback routine for each
+packet, or with
+.B pcap_next()
+or
+.BR pcap_next_ex() ,
+which return the next packet.
+The callback for
+.B pcap_dispatch()
+and
+.BR pcap_loop()
+is supplied a pointer to a
+.IR "struct pcap_pkthdr" ,
+which includes the following members:
+.RS
+.TP
+.B ts
+a
+.I struct timeval
+containing the time when the packet was captured
+.TP
+.B caplen
+a
+.I bpf_u_int32
+giving the number of bytes of the packet that are available from the
+capture
+.TP
+.B len
+a
+.I bpf_u_int32
+giving the length of the packet, in bytes (which might be more than the
+number of bytes available from the capture, if the length of the packet
+is larger than the maximum number of bytes to capture).
+.RE
+.PP
+.B pcap_next_ex()
+supplies that pointer through a pointer argument.
+.B pcap_next()
+is passed an argument that points to a
+.I struct pcap_pkthdr
+structure, and fills it in.
+.PP
+The callback is also supplied a
+.I const u_char
+pointer to the first
+.B caplen
+(as given in the
+.I struct pcap_pkthdr
+a pointer to which is passed to the callback routine)
+bytes of data from the packet.  This won't necessarily be the entire
+packet; to capture the entire packet, you will have to provide a value
+for
+.I snaplen
+in your call to
+.B pcap_open_live()
+that is sufficiently large to get all of the packet's data - a value of
+65535 should be sufficient on most if not all networks).  When reading
+from a ``savefile'', the snapshot length specified when the capture was
+performed will limit the amount of packet data available.
+.B pcap_next()
+returns that pointer;
+.B pcap_next_ex()
+supplies that pointer through a pointer argument.
+.SH BACKWARDS COMPATIBILITY
+.PP
+In versions of libpcap prior to 1.0, the
+.B pcap.h
+header file was not in a
+.B pcap
+directory on most platforms; if you are writing an application that must
+work on versions of libpcap prior to 1.0, include
+.BR <pcap.h> ,
+which will include
+.B <pcap/pcap.h>
+for you, rather than including
+.BR <pcap/pcap.h> .
+.PP
+.B pcap_create()
+and
+.B pcap_activate()
+were not available in versions of libpcap prior to 1.0; if you are
+writing an application that must work on versions of libpcap prior to
+1.0, either use
+.B pcap_open_live()
+to get a handle for a live capture or, if you want to be able to use the
+additional capabilities offered by using
+.B pcap_create()
+and
+.BR pcap_activate() ,
+use an
+.BR autoconf (1)
+script or some other configuration script to check whether the libpcap

+.TH PCAP_BREAKLOOP 3PCAP "5 April 2008"
+.SH NAME
+pcap_breakloop \- force a pcap_dispatch() or pcap_loop() call to return
+.SH SYNOPSIS
+.nf
+.ft B
+#include <pcap/pcap.h>
+.ft
+.LP
+.ft B
+void pcap_breakloop(pcap_t *);
+.ft
+.fi
+.SH DESCRIPTION
+.B pcap_breakloop()
+sets a flag that will force
+.B pcap_dispatch()
+or
+.B pcap_loop()
+to return rather than looping; they will return the number of packets
+that have been processed so far, or \-2 if no packets have been
+processed so far.
+.PP
+This routine is safe to use inside a signal handler on UNIX or a console
+control handler on Windows, as it merely sets a flag that is checked
+within the loop.
+.PP
+The flag is checked in loops reading packets from the OS - a signal by
+itself will not necessarily terminate those loops - as well as in loops
+processing a set of packets returned by the OS.
+.ft B
+Note that if you are catching signals on UNIX systems that support
+restarting system calls after a signal, and calling pcap_breakloop()
+in the signal handler, you must specify, when catching those signals,
+that system calls should NOT be restarted by that signal.  Otherwise,
+if the signal interrupted a call reading packets in a live capture,
+when your signal handler returns after calling pcap_breakloop(), the
+call will be restarted, and the loop will not terminate until more
+packets arrive and the call completes.
+.PP
+Note also that, in a multi-threaded application, if one thread is
+blocked in
+.BR pcap_dispatch() ,
+.BR pcap_loop() ,
+.BR pcap_next() ,
+or
+.BR pcap_next_ex() ,
+a call to
+.B pcap_breakloop()
+in a different thread will not unblock that thread; you will need to use
+whatever mechanism the OS provides for breaking a thread out of blocking
+calls in order to unblock the thread, such as thread cancellation in
+systems that support POSIX threads.
+.ft R
+.PP
+Note that
+.B pcap_next()
+and
+.B pcap_next_ex()
+will, on some platforms, loop reading packets from the OS; that loop
+will not necessarily be terminated by a signal, so
+.B pcap_breakloop()
+should be used to terminate packet processing even if
+.B pcap_next()
+or
+.B pcap_next_ex()
+is being used.
+.PP
+.B pcap_breakloop()
+does not guarantee that no further packets will be processed by
+.B pcap_dispatch()
+or
+.B pcap_loop()
+after it is called; at most one more packet might be processed.
+.PP
+If \-2 is returned from
+.B pcap_dispatch()
+or
+.BR pcap_loop() ,
+the flag is cleared, so a subsequent call will resume reading packets. 
+If a positive number is returned, the flag is not cleared, so a
+subsequent call will return \-2 and clear the flag.

+.I optimize
+controls whether optimization on the resulting code is performed.
+.I netmask
+specifies the IPv4 netmask of the network on which packets are being

+the filter program.  If the netmask of the network on which packets are
+being captured isn't known to the program, or if packets are being
+captured on the Linux "any" pseudo-interface that can capture on more

+.ft
+.LP
+.ft B
+pcap_t *pcap_create(const char *source, char *errbuf);
+.ft
+.fi
+.SH DESCRIPTION
+.B pcap_create()
+is used to create a packet capture handle to look
+at packets on the network.
+.I source
+is a string that specifies the network device to open; on Linux systems
+with 2.2 or later kernels, a
+.I source
+argument of "any" or
+.B NULL
+can be used to capture packets from all interfaces.
+.PP
+The returned handle must be activated with
+.B pcap_activate()
+before packets can be captured
+with it; options for the capture, such as promiscuous mode, can be set
+on the handle before activating it.
+.SH RETURN VALUE
+.B pcap_create()
+returns a
+.I pcap_t *
+on success and
+.B NULL
+on failure.
+If
+.B NULL
+is returned,
+.I errbuf
+is filled in with an appropriate error message.
+.I errbuf
+is assumed to be able to hold at least
+.B PCAP_ERRBUF_SIZE
+chars.

+.SH DESCRIPTION
+.B pcap_findalldevs()
+constructs a list of network devices that can be opened with
+.B pcap_create()
+and
+.B pcap_activate()
+or with
+.BR pcap_open_live() .
+(Note that there may be network devices that cannot be opened by the
+process calling
+.BR pcap_findalldevs() ,
+because, for example, that process might not have sufficient privileges
+to open them for capturing; if so, those devices will not appear on the
+list.)
+.I alldevsp
+is set to point to the first element of the list; each element of the
+list is of type
+.BR pcap_if_t ,
+and has the following members:
+.RS
+.TP
+.B next
+if not
+.BR NULL ,
+a pointer to the next element in the list;
+.B NULL
+for the last element of the list
+.TP
+.B name
+a pointer to a string giving a name for the device to pass to
+.B pcap_open_live()
+.TP
+.B description
+if not
+.BR NULL ,
+a pointer to a string giving a human-readable description of the device
+.TP
+.B addresses
+a pointer to the first element of a list of addresses for the interface
+.TP
+.B flags
+interface flags:
+.RS
+.TP
+.B PCAP_IF_LOOPBACK
+set if the interface is a loopback interface
+.RE
+.RE
+.PP
+Each element of the list of addresses is of type
+.BR pcap_addr_t ,
+and has the following members:
+.RS
+.TP
+.B next
+if not
+.BR NULL ,
+a pointer to the next element in the list;
+.B NULL
+for the last element of the list
+.TP
+.B addr
+a pointer to a
+.B "struct sockaddr"
+containing an address
+.TP
+.B netmask
+if not
+.BR NULL ,
+a pointer to a
+.B "struct sockaddr"
+that contains the netmask corresponding to the address pointed to by

+.TP
+.B broadaddr
+if not
+.BR NULL ,
+a pointer to a

+may be null if the interface doesn't support broadcasts
+.TP
+.B dstaddr
+if not
+.BR NULL ,
+a pointer to a
+.B "struct sockaddr"
+that contains the destination address corresponding to the address pointed
+to by
+.BR addr ;
+may be null if the interface isn't a point-to-point interface
+.RE
+.PP
+Note that not all the addresses in the list of addresses are

+.nf
+.ft B
+#include <pcap/pcap.h>
+.ft
+.LP
+.ft B
+int pcap_get_selectable_fd(pcap_t *p);
+.ft
+.fi
+.SH DESCRIPTION
+.B pcap_get_selectable_fd()
+returns, on UNIX, a file descriptor number for a file descriptor on
+which one can
+do a
+.B select()
+or
+.B poll()
+to wait for it to be possible to read packets without blocking, if such
+a descriptor exists, or \-1, if no such descriptor exists.  Some network
+devices opened with
+.B pcap_create()
+and
+.BR pcap_activate() ,
+or with
+.BR pcap_open_live() ,
+do not support
+.B select()
+or
+.B poll()
+(for example, regular network devices on FreeBSD 4.3 and 4.4, and Endace
+DAG devices), so \-1 is returned for those devices.
+.PP
+Note that on most versions of most BSDs (including Mac OS X)
+.B select()
+and
+.B poll()
+do not work correctly on BPF devices;
+.B pcap_get_selectable_fd()
+will return a file descriptor on most of those versions (the exceptions
+being FreeBSD 4.3 and 4.4), a simple
+.B select()
+or
+.B poll()
+will not return even after the read timeout expires.  To work around
+this, an application that uses
+.B select()
+or
+.B poll()
+to wait for packets to arrive must put the
+.B pcap_t
+in non-blocking mode, and must arrange that the
+.B select()
+or
+.B poll()
+have a timeout less than or equal to the read timeout,
+and must try to read packets after that timeout expires, regardless of
+whether
+.B select()
+or
+.B poll()
+indicated that the file descriptor for the
+.B pcap_t
+is ready to be read or not.  (That workaround will not work in FreeBSD
+4.3 and later; however, in FreeBSD 4.6 and later,
+.B select()
+and
+.B poll()
+work correctly on BPF devices, so the workaround isn't necessary,
+although it does no harm.)
+.PP
+Note also that
+.B poll()
+doesn't work on character special files, including BPF devices, in Mac
+OS X 10.4 and 10.5, so, while
+.B select()
+can be used on the descriptor returned by
+.BR pcap_get_selectable_fd() ,
+.B poll()
+cannot be used on it those versions of Mac OS X.  Kqueues also don't
+work on that descriptor.
+.PP
+.B pcap_get_selectable_fd()
+is not available on Windows.
+.SH RETURN VALUE
+A selectable file descriptor is returned if one exists; otherwise, \-1
+is returned.

+.ft B
+int pcap_inject(pcap_t *p, const void *buf, size_t size);
+int pcap_sendpacket(pcap_t *p, const u_char *buf, int size);
+.ft
+.fi
+.SH DESCRIPTION
+.B pcap_inject()
+sends a raw packet through the network interface;
+.I buf
+points to the data of the packet, including the link-layer header, and
+.I size
+is the number of bytes in the packet.
+.PP
+Note that, even if you successfully open the network interface, you
+might not have permission to send packets on it, or it might not support
+sending packets; as
+.I pcap_open_live()
+doesn't have a flag to indicate whether to open for capturing, sending,
+or capturing and sending, you cannot request an open that supports
+sending and be notified at open time whether sending will be possible.
+Note also that some devices might not support sending packets.
+.PP
+Note that, on some platforms, the link-layer header of the packet that's
+sent might not be the same as the link-layer header of the packet
+supplied to
+.BR pcap_inject() ,
+as the source link-layer address, if the header contains such an
+address, might be changed to be the address assigned to the interface on
+which the packet it sent, if the platform doesn't support sending
+completely raw and unchanged packets.  Even worse, some drivers on some
+platforms might change the link-layer type field to whatever value
+libpcap used when attaching to the device, even on platforms that
+.I do
+nominally support sending completely raw and unchanged packets.
+.PP
+.B pcap_sendpacket()
+is like
+.BR pcap_inject() ,
+but it returns 0 on success, rather than returning the number of bytes
+written.
+.RB ( pcap_inject()
+comes from OpenBSD;
+.B pcap_sendpacket()
+comes from WinPcap.  Both are provided for compatibility.)
+.SH RETURN VALUE
+.B pcap_inject()
+returns the number of bytes written on success and \-1 on failure.
+.PP
+.B pcap_sendpacket()
+returns 0 on success and \-1 on failure.
+.PP
+If \-1 is returned,
+.B pcap_geterr()
+or
+.B pcap_perror()
+may be called with
+.I p
+as an argument to fetch or display the error text.

+.TH PCAP_LOOP 3PCAP "5 April 2008"
+.SH NAME
+pcap_loop, pcap_dispatch \- process packets from a live capture or savefile
+.SH SYNOPSIS
+.nf
+.ft B
+#include <pcap/pcap.h>
+.ft
+.LP
+.ft B
+typedef void (*pcap_handler)(u_char *user, const struct pcap_pkthdr *h,
+.ti +8
+			     const u_char *bytes);
+.ft
+.LP
+.ft B
+int pcap_loop(pcap_t *p, int cnt,
+.ti +8
+pcap_handler callback, u_char *user);
+int pcap_dispatch(pcap_t *p, int cnt,
+.ti +8
+pcap_handler callback, u_char *user);
+.ft
+.fi
+.SH DESCRIPTION
+.B pcap_loop()
+processes packets from a live capture or ``savefile'' until
+.I cnt
+packets are processed, the end of the ``savefile'' is
+reached when reading from a ``savefile'',
+.B pcap_breakloop()
+is called, or an error occurs.
+It does
+.B not
+return when live read timeouts occur.
+A value of \-1 or 0 for
+.I cnt
+is equivalent to infinity, so that packets are processed until another
+ending condition occurs.
+.PP
+.B pcap_dispatch()
+processes packets from a live capture or ``savefile'' until
+.I cnt
+packets are processed, the end of the current bufferful of packets is
+reached when doing a live capture, the end of the ``savefile'' is
+reached when reading from a ``savefile'',
+.B pcap_breakloop()
+is called, or an error occurs.
+Thus, when doing a live capture,
+.I cnt
+is the maximum number of packets to process before returning, but is not
+a minimum number; when reading a live capture, only one
+bufferful of packets is read at a time, so fewer than
+.I cnt
+packets may be processed. A value of \-1 or 0 for
+.I cnt
+causes all the packets received in one buffer to be processed when
+reading a live capture, and causes all the packets in the file to be
+processed when reading a ``savefile''.
+.PP
+.ft B
+(In older versions of libpcap, the behavior when
+\fIcnt\fP
+was 0 was undefined; different platforms and devices behaved
+differently, so code that must work with older versions of libpcap
+should use \-1, nor 0, as the value of
+\fIcnt\fP.)
+.ft R
+.PP
+.I callback
+specifies a routine to be called with three arguments:
+a
+.I u_char
+pointer which is passed in the
+.I user
+argument to
+.B pcap_loop()
+or
+.BR pcap_dispatch() ,
+a
+.I const struct pcap_pkthdr
+pointer pointing to the packet time stamp and lengths, and a
+.I const u_char
+pointer to the first
+.B caplen
+(as given in the
+.I struct pcap_pkthdr
+a pointer to which is passed to the callback routine)
+bytes of data from the packet.
+.SH RETURN VALUE
+.B pcap_loop()
+returns 0 if
+.I cnt
+is exhausted, \-1 if an error occurs, or \-2 if the loop terminated due
+to a call to
+.B pcap_breakloop()
+before any packets were processed.
+It does
+.B not
+return when live read timeouts occur; instead, it attempts to read more
+packets.
+.PP
+.B pcap_dispatch()
+returns the number of packets processed on success; this can be 0 if no
+packets were read from a live capture (if, for example, they were
+discarded because they didn't pass the packet filter, or if, on
+platforms that support a read timeout that starts before any packets
+arrive, the timeout expires before any packets arrive, or if the file
+descriptor for the capture device is in non-blocking mode and no packets
+were available to be read) or if no more packets are available in a
+``savefile.''  It returns \-1 if an error occurs or \-2 if the loop
+terminated due to a call to
+.B pcap_breakloop()
+before any packets were processed.
+.ft B
+If your application uses pcap_breakloop(),
+make sure that you explicitly check for \-1 and \-2, rather than just
+checking for a return value < 0.
+.ft R
+.PP
+If \-1 is returned,
+.B pcap_geterr()
+or
+.B pcap_perror()
+may be called with
+.I p
+as an argument to fetch or display the error text.

+int promisc, int to_ms, char *errbuf);
+.ft
+.fi
+.SH DESCRIPTION
+.B pcap_open_live()
+is used to obtain a packet capture handle to look
+at packets on the network.
+.I device
+is a string that specifies the network device to open; on Linux systems
+with 2.2 or later kernels, a
+.I device
+argument of "any" or
+.B NULL
+can be used to capture packets from all interfaces.
+.PP
+.I snaplen
+specifies the snapshot length to be set on the handle.
+.PP
+.I promisc
+specifies if the interface is to be put into promiscuous mode.
+.PP
+.I to_ms
+specifies the read timeout in milliseconds.
+.SH RETURN VALUE
+.B pcap_open_live()
+returns a
+.I pcap_t *
+on success and
+.B NULL
+on failure.
+If
+.B NULL
+is returned,
+.I errbuf
+is filled in with an appropriate error message.
+.I errbuf
+may also be set to warning text when
+.B pcap_open_live()
+succeds; to detect this case the caller should store a zero-length string in
+.I errbuf
+before calling
+.B pcap_open_live()
+and display the warning to the user if
+.I errbuf
+is no longer a zero-length string.
+.I errbuf
+is assumed to be able to hold at least
+.B PCAP_ERRBUF_SIZE
+chars.

+.TH PCAP_SETNONBLOCK 3PCAP "5 April 2008"
+.SH NAME
+pcap_setnonblock, pcap_getnonblock \- set or get the state of
+non-blocking mode on a capture device
+.SH SYNOPSIS
+.nf
+.ft B
+#include <pcap/pcap.h>
+.ft
+.LP
+.nf
+.ft B
+char errbuf[PCAP_ERRBUF_SIZE];
+.ft
+.LP
+.ft B
+int pcap_setnonblock(pcap_t *p, int nonblock, char *errbuf);
+int pcap_getnonblock(pcap_t *p, char *errbuf);
+.ft
+.fi
+.SH DESCRIPTION
+.B pcap_setnonblock()
+puts a capture handle into ``non-blocking'' mode, or takes it out
+of ``non-blocking'' mode, depending on whether the
+.I nonblock
+argument is non-zero or zero.  It has no effect on ``savefiles''.
+If there is an error, \-1 is returned and
+.I errbuf
+is filled in with an appropriate error message; otherwise, 0 is
+returned.
+In
+``non-blocking'' mode, an attempt to read from the capture descriptor
+with
+.B pcap_dispatch()
+will, if no packets are currently available to be read, return 0
+immediately rather than blocking waiting for packets to arrive.
+.B pcap_loop()
+and
+.B pcap_next()
+will not work in ``non-blocking'' mode.
+.SH RETURN VALUE
+.B pcap_getnonblock()
+returns the current ``non-blocking'' state of the capture descriptor; it
+always returns 0 on ``savefiles''.
+If there is an error, \-1 is returned and
+.I errbuf
+is filled in with an appropriate error message.
+.PP
+.I errbuf
+is assumed to be able to hold at least
+.B PCAP_ERRBUF_SIZE
+chars.
