-6 and -PE or -PN or -PP

[jah <jah () zadkiel plus com>]

Hi.

Attached is null_device.patch - a draft patch to catch:

nmap -6 -PE 2001::a08

Starting Nmap 4.62 ( http://nmap.org ) at 2008-05-12 02:14 GMT Standard Time
Assertion failed: device != NULL, file ..\tcpip.cc, line 931

which also happens for -PN and -PP.


regards,

jah
