ssh errors

[Shawn Badger]

Have you checked your permissions on /bin/sh? Your system may have
compromised and they will sometimes change the permission on some key
files such as ls or sh to get you to run the corrupted files with root
privileges. I would download and run chkrootkit to see if the files have
been changed.
