First off post in the correct section.
As for your "problem" it works for me.
I would suggest that you look at the error above. You will need to configure the file in question.Code:root@dorkness:/pentest/voip/iwar#./iwar -v iWar version 0.08-CVS-12-29-2008 By Da Beave (email@example.com)
There is a whole bunch of documentation within the above directory that will help.
