Hiding your self while you are on ServER!

Hi there Spender
again we meet.
I was wondering since grsecurity has the power of hiding process, do you think there's away you can be logged on to the server via username ( SSH or telnet ) such that even if other users do w or who they cant see you ? I was thinking of greating a special shell for that user and Givin it the h , I tried and did not work, maybe we have to hide something in SSH session as well.
any thoughts?

This has been discussed before on the forums. All you need to do it is the /proc restrictions, and you need to make some small userspace changes. You need to make /var/run/utmp and /var/log/wtmp only readable by root and group utmp (a group that you create). You should then make who and last sgid utmp. The /proc restrictions will take care of w.
