http://www.chkrootkit.org That site is a good start. then from there I like to check the /var/log directory, run dmesg and see if the port was ever put in listening mode. Bring over a clean ps, ls, du, df, lsof, netstat and from there you can start to get a real picture of the machine. Eric Gunnett System Administrator Zoovy, Inc. eric () zoovy com

Hello, I have a redhat 7.2 server that stopped accepting my ssh login. I can still use my login at the terminal. I also noticed that the host key changed. My only guess at this point is that the box was probably compromised. Any good software out there to help me figure it out? Any other ideas as to what would cause this? Anything helps, Melissa (THIS IS IN NO WAY AFFILIATED WITH UAB.
