The hidden process check of chkrootkit can and will sometimes report hidden processes when there are none. These *false* alarms will happen mostly when you're running many dynamic processes. Like Apache, MySQL or ASP. Why does it happen? Chkrootkit compares the processes in the /proc/ directory with those shown by the command "ps". If both outputs don't match, then it'll give alert. However, the comparision takes a few moments and if a process ends during the comparision, then that will cause an false alarm. How to run the test manually for cross checking: As root: go to the directory where you have chkrootkit installed and issue the command shown below: ./chkrootkit -x lkm That will show a detailed listing of the suspicious processes in question and can help you to look further into the issue. If the listing comes up empty (see example below), then there is nothing to worry about. [root admin]# cd /home/security/chkrootkit/ [root chkrootkit]# ./chkrootkit -x lkm ROOTDIR is `/' ### ### Output of: ./chkproc -v ### [root chkrootkit]# If it shows process numbers instead of the empty listing like shown above, then you can (and should) start to track down the hidden processes by evaluating your /proc/ directory manually - with special attention to the directories with the same number as the hidden processes named by chkrootkit. -- With best regards, Michael Stauber [EMAIL PROTECTED] Unix/Linux Support Engineer _______________________________________________ cobalt-security mailing list [EMAIL PROTECTED] http://list.cobalt.com/mailman/listinfo/cobalt-security
