Prevent users from viewing other user processes?
I recently installed a new copy of Mandrake 9.2 and set the security level to 4 (Higher). I noticed when I started creating users that people could not view the process list because the /proc dir was chmoded 550 with root owner/group.
If I allow access to the proc, that means they can see all processes. I don't want that. I tried making a small program to prevent `ps -a` or `ps -U root`, but it doesn't work because it has to call the original PS at some point.
Is there a simple way to limit users to only viewing their processes? Or, if not, change it so that when a process is created, it is owned by that user and group and chmodded to 550?
(If anyone cares... ps1 and ps2 tests:
Thanks in advance for taking a look at my problem.
