Could you please post the commands you used?
I have been unable to recreate this.
amap, the protocol version detection tool by THC is installed incorrectly.
It attempts to load the file: ../usr/etc/appdefs.trig which is installed in /usr/etc/appdefs.trig. So amap only works if the current path is / or 1 directory level deep, eg. /etc, /pentest.
The root cause of the issue is that by default amap will be installed into .../bin and .../etc of: /usr/local. The solution is to use ./configure --prefix /usr/
I also noticed there is a bug in the official release of amap. The Makefile copies amap to /usr/bin/amap and /usr/bin/amap6 then tries and fails to make a symlink to /usr/bin/amap6. This wastes 80K which is no big deal.
Fixed in svn. Should update in a few days
I'd just like to point out that amap hasn't been updated since 2006, it's doubtful you'll get anything useful from it vs. nmap.
I'm a compulsive post editor, you might wanna wait until my post has been online for 5-10 mins before quoting it as it will likely change.
I know I seem harsh in some of my replies. SORRY! But if you're doing something illegal or posting something that seems to be obvious BS I'm going to call you on it.
Since this issue is fixed, this thread is closed.
If there are other problems once the updated version hits the repo make a new thread please.
Thanks for reporting the issue urbanadventurer
