You can also use RPM to check the integrity of your file, especially the 
critical binary ones (ie. ls, ps, top, cd, etc.). Look at "man rpm", look at 
the option verivy (-V) and Verify all (-Va). It's also explained in RH manual 
/ Security guide at www.redhat.com. I think it's under the chapter "RPM as 
intrusion detection", or something like that.
