Root Kit Hunter, aka “rkhunter” is a great little utility for *nix based systems that will check for known vulnerabilities and backdoors installed on a Linux box, otherwise know as “root kits”.
Once you install it, simply “su root”, then try running it with the following arguments:
$ rkhunter –checkall –createlogfile
Process only took about 5 minutes on my system, and gave me one warning (I won’t say what so none of you try to hack my machine).
That’s pretty cool. Do you run that in conjunction with chkrootkit (http://www.chkrootkit.org/)?
haven’t seen that one yet. But if it’s open source and available for Linux I’d recommend it.
