Ncrack Bug report
From: "Cornelius Krasel" <cornelius.krasel () web de>
Date: Sun, 6 Feb 2011 17:57:23 +0100 (CET)


I am trying to retrieve the admin password from our own Cisco WRT54GL using the latest ncrack binary for Windows.


$Windows XP> ncrack -vvvv --user admin

Starting Ncrack 0.3ALPHA ( http://ncrack.org/ ) at 2011-02-06 17:09 Westeuropäische Normalzeit

Rate: 31.74; Found: 0; About 77.07% done; ETC: 17:10 (00:00:24 remaining)

Strange connect error from (10048): No such file or directory

Assertion failed: 0, file .\src\nsock_core.c, line 404

This application has requested the Runtime to terminate it in an unusual way.

Please contact the application's support team for more information.


Repeating the command, ncrack always fails at around the same space covered (77.79%, 76.65%), which makes me think that 
ncrack has discovered the right password but fails on the reply of the router. If I mess around with the timing by 
using "ncrack -T2", the program fails immediately with the same error message. With "ncrack -T1" or "ncrack -T0" the 
program just stops without producing any result, apparently not having scanned any space. "-T3" seems to be identical 
with no options; "-T4" and "-T5" fail at around 72%. Any help would be greatly appreciated because I don't want to 
reset the router :-).
