a layer 4 protocol used mostly for telephony related applications.
This brings the following new features:
o SCTP INIT chunk port scan (-sY): open ports return an INIT-ACK
chunk, closed ones an ABORT chunk. This is the SCTP equivalent
of a TCP SYN stealth scan.
o SCTP COOKIE-ECHO chunk port scan (-sZ): open ports are silent,
closed ports return an ABORT chunk.
o SCTP INIT chunk ping probes (-PY): host discovery using SCTP
INIT chunk packets.
o SCTP-specific IP protocol scan (-sO -p sctp).
o SCTP-specific traceroute support (--traceroute).
o The ability to use the deprecated Adler32 algorithm as specified
in RFC 2960 instead of CRC32C from RFC 4960 (--adler32).
o 42 well-known SCTP ports were added to the nmap-services file.
Part of the work on SCTP support was kindly sponsored by
Compass Security AG, Switzerland. [Daniel Roethlisberger]

|
|

|
|
* (contact sales@insecure.com). Dozens of software vendors already *
|
|
* license Nmap technology such as host discovery, port scanning, OS *
|
|
* detection, and version detection. *
|
|
* *
|
|
* Note that the GPL places important restrictions on "derived works", yet *
|
|
* it does not provide a detailed definition of that term. To avoid *
|
|
* misunderstandings, we consider an application to constitute a *
|
|
* "derivative work" for the purpose of this license if it does any of the *
|
|
* following: *
|
|
* o Integrates source code from Nmap *
|
|
* o Reads or includes Nmap copyrighted data files, such as *
|
|
* nmap-os-db or nmap-service-probes. *
|
|
* o Executes Nmap and parses the results (as opposed to typical shell or *
|
|
* execution-menu apps, which simply display raw Nmap output and so are *
|
|
* not derivative works.) *
|
|
* o Integrates/includes/aggregates Nmap into a proprietary executable *
|
|
* installer, such as those produced by InstallShield. *
|
|
* o Links to a library or executes a program that does any of the above *
|
|
* *
|
|
* The term "Nmap" should be taken to also include any portions or derived *
|
|
* works of Nmap. This list is not exclusive, but is meant to clarify our *
|
|
* interpretation of derived works with some common examples. Our *
|
|
* interpretation applies only to Nmap--we don't speak for other people's *
|
|
* GPL works. *
|
|
* *
|
|
* If you have any questions about the GPL licensing restrictions on using *
|
|
* Nmap in non-GPL works, we would be happy to help. As mentioned above, *
|
|
* we also offer alternative license to integrate Nmap into proprietary *
|
|
* applications and appliances. These contracts have been sold to dozens *
|
|
* of software vendors, and generally include a perpetual license as well *
|
|
* as providing for priority support and updates as well as helping to *
|
|
* fund the continued development of Nmap technology. Please email *
|
|
* sales@insecure.com for further information. *
|
|
* *
|
|
* As a special exception to the GPL terms, Insecure.Com LLC grants *
|
|
* permission to link the code of this program with any version of the *
|
|
* OpenSSL library which is distributed under a license identical to that *
|
|
* listed in the included COPYING.OpenSSL file, and distribute linked *
|
|
* combinations including the two. You must obey the GNU GPL in all *
|
|

|
|
* this file, you may extend this exception to your version of the file, *
|
|
* but you are not obligated to do so. *
|
|
* *
|
|
* If you received these files with a written license agreement or *

* contract stating terms other than the terms above, then that *
|

* *
|
|
* Source is provided to this software because we believe users have a *
|
|
* right to know exactly what a program is going to do before they run it. *
|
|
* This also allows you to audit the software for security holes (none *
|
|
* have been found so far). *
|
|
* *
|
|
* Source code also allows you to port Nmap to new platforms, fix bugs, *
|
|
* and add new features. You are highly encouraged to send your changes *
|
|
* to nmap-dev@insecure.org for possible incorporation into the main *
|
|
* distribution. By sending these changes to Fyodor or one of the *
|
|
* Insecure.Org development mailing lists, it is assumed that you are *
|
|
* offering the Nmap Project (Insecure.Com LLC) the unlimited, *
|
|
* non-exclusive right to reuse, modify, and relicense the code. Nmap *
|
|
* will always be available Open Source, but this is important because the *
|
|
* inability to relicense code has caused devastating problems for other *
|
|
* Free Software projects (such as KDE and NASM). We also occasionally *
|
|
* relicense the code to third parties as discussed above. If you wish to *
|
|
* specify special license conditions of your contributions, just say so *
|
