This establishes a more regular syntax for some options that disable
phases of a scan:
-n no reverse DNS
-Pn no host discovery
-sn no port scan
Also, the -sP was possibly misleading because the 'P' suggests "ping
scan," when you can now do more than just pinging when you disable port
scanning. For example, -sC -sn and -sn -Pn --traceroute make sense.
entries:
o [NSE] Raw packet sending at the IP layer is now supported, in addition to
the Ethernet sending functionality. Packets to send start with an IPv4
header and can be sent to arbitrary hosts. [Kris]
o [NSE] Added the ipidseq script to classify a host's IP ID sequence numbers
in the same way Nmap does. This can be used to test hosts' suitability for
Nmap's Idle Scan (-sI), i.e. check if a host is an idle zombie. This is
the first script to use the new raw IP sending functionality in NSE. [Kris]
o [NSE] Added the function nmap.is_privileged() to tell a script if, as far
as Nmap's concerned, it can do privileged operations. For instance, this
can be used to see if a script should be able to open a raw socket or
Ethernet interface. [Kris]
o [NSE] Added the function nmap.get_ports() to allow a script to iterate
over a host's port tables matching a certain protocol and state. [Kris,
Patrick]
Adding documentation for the various new parallelism features
NSE has recently added including mutexes, condition variables,
child coroutine support, and new threads.
with modifications from [2].
** Short description from [1] **
I have created a patch to NSE that replaces runlevels with a table of
dependencies that clearly outlines what other scripts the script
depends on. The table is of the form:
dependences = {"script1", script2", ...}
Runlevels become an internal representation of the order of scripts
that are generated by the dependencies. Dependencies only enforce
an execution order and not a requirement for execution.
