Show hidden processes
Hello Guys,
how can i discover hidden processes running? Already running rkhunter, chrootkit.
[root@kenny ~]# ps auxfww
USER PID %CPU %MEM SIZE RSS TTY STAT START TIME COMMAND
Segmentation fault
[root@kenny ~]#
This just appen when i use flag "f = --full". Some running process causing this.
Regards,

I seriously doubt any running process that you're asking ps to display is causing this. This is a bug in the ps command itself.

You can try rebooting the server during of peak time and see if that solve the issue of segmentation fault.

Here's what I do to find hidden processes...
cd /proc
for i in `seq 1 33000`; do test -d $i done
If your server is hacked and your processes are hidden they won't show up with the top or ps command etc... the command above will still show everything running
I'd run a memtest and a drivetest as well if you are getting that segfault error...
