[root@kylesplace chkrootkit-0.47]#
I run OSSEC, denyhosts (with extremely strict policies), mod_security. I check my logwatches every day, nothing out of the ordinary ever. I nmap the box remotely to check for suspicious ports, nothing. I even watch iptraf for anything weird. I also run rkhunter and chkrootkit every week, and have found nothing. I lsof'd each of the 79 pids and nothing came up. Can anyone tell me what this means?
