You can try booting your server with knoppix ( http://www.knoppix.org ), and look for hidden files. If possible, do not allow Loadable module support , maybe this can avoid future problems with lkm. I am not sure if building a new kernel works. But if you have good results with that, tell me. Sorry about the porr English. []'s

A few days ago I downloaded chkrootkit and it consistently gives the same output (>20 hidden processes) when checking for LKM rootkit: Checking `lkm'... You have 38 process hidden for readdir command Warning: Possible LKM Trojan installed This is even after reboots. How can I check if this is actually the work of the LKM? Or any other rootkit for that matter?What does "chkrootkit -x lkm" return? If anything... If it shows PIDs you'll want to hunt through /proc manually for those processes.
