This is interesting since I was able to reproduce the infinite loop by just
running bruteTelnet.nse against my localhost.
nmap -T4 -v -sS -sV -O -n --script=all --script-trace -iL test.lis
ugh, i'll bet the problem is that bruteTelnet.nse never closes the
ports it opens and the garbage collector never the socket because
there is always a reference to it.
I just commited a patch to nse_nsock.cc which should fix this issue:
If a second connect() request is issued on an already open socket, the
socket gets closed before the connect is processed.
This solved the infinite loop with bruteTelnet.nse for me (although the
script took 6 minutes to finish its execution).
It would be great if you could test the patch, before the stable release
I think we'll need to reconsider the open port cap and garbage
