Get a clean install/binary of top, ps, netstat, etc. and check and see if there's any processes in netstat that aren't listed in ps.

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? Regards, Janus N. Tøndering -- Janus N.
