xchat auth is a simple fake-ident program. This means you can use any
username in xchat without the ~ infront of your username, and the auth port
will only be open while xchat is actually connecting to a server. It should be
used on machines with only 1 user!
This is highly experimental software! It must be made suidroot, therefore
there is a danger of buffer overflow, and getting hacked. USE AT OWN RISK!
1) download xchat_auth.c
2) compile it:
gcc xchat_auth.c -o xchat_auth
3) copy the binary into your $HOME/auth/, e.g.
cp xchat_auth ~/auth/
4) make the binary suid-root, e.g.
chown root xchat_auth
chgrp root xchat_auth
chmod +s xchat_auth
