I executed this command and it seemed to run without a problem.
It didn't fix my problem though. I still can't startx and when I
try to log into my account it says "No directory /home/me" but
it _IS_ there with rwx permissions for owner.
I plan to re-install but after seeing the thread on compromised
systems I started to wonder. I ran nmap:
PORT STATE SERVICE
22/tcp open ssh
80/tcp open http
111/tcp open rpcbind
443/tcp open https
515/tcp open printer
I have (had) a web server running
I tried setting up ssh once and I believe it was set up to use
keys (SSH2).
I ran rpm -Va:

Many lines appear to suggest it's compromised but why would they
attack the RHN and other Python compiler scripts. Could this be
related to having changed file permissions?
I tried to run chkrootkit but I couldn't find it though I think
it's installed somewhere.
Does it look to YOU like someone's hijacked my system beyond
repair with a reinstall?
Thanks and sorry for the length (of the email).
Bruce
