Another neat trick is let RPM help you find altered executables that it
knows about, in case the rootkit replaced some other things (again,
better to reinstall from scratch):

  rpm -Va

The first three characters are the most important to look at, they'll
tell you if the size/md5sum is off. Here's a quick cheatsheet paste from
the man page:

  S file Size differs
  M Mode differs (includes permissions and file type)
  5 MD5 sum differs
  D Device major/minor number mismatch
  L readLink(2) path mismatch
  U User ownership differs
  G Group ownership differs
  T mTime differs

You'll see a lot of stuff, don't panic -- it's very common to get
changes listed in /etc/ and /usr/share/, among others. Pay keen
attention to anything in bin (/bin, /sbin, /usr/bin, /usr/sbin, etc) as
they are the most likely targets.
