Need Help Find a Security Hole in Server

Ok, so someone hacked into my server and is trying to dos other servers. I have no demo accounts so I have rules that out. It's most likely an insecure script that a client has. Is it possible to locate the vulnerability?

I am looking through logs and everything and this is so far the only thing I have to go on:

./f3 200.218.184.194

Any ideas? Thanks!!!
