Hi there,
Thanx for all who replied. The problem was with permissions in
/dev/kmem and /dev/drum. A chmod a+r solved the problem. I still don't know
what caused the problem with the permissions.
--------Original Problem--------------------------------
Hi managers,
I have a problem with "ps" on a Sparc running SunOs4.1.3. If I run "ps"
as a user other than "root", the result is:
[mymachine]> ps
ps: cannot open /dev/mem: Permission denied
ps: could not read kernel VM
[mymachine]>
I've checked the permissions on /dev/mem and they looks normal:
[mymachine]> ls -al /dev/mem
crw-r----- 1 root 3, 0 Sep 23 1992 /dev/mem
[mymachine]>
Maybe the problem is related to some accounting functions that i've
turned on in the machine.
Any help will be apreciated.
Thanx in advance
Jorge

Solution:
As I said above...
[mymachine]> ls -lg /dev/kmem
crw-r----- 1 root kmem 3, 1 Mar 5 1993 /dev/kmem
[mymachine]> ps (as other than root!)
Permission denied on /dev/kmem blah blah blah.....
[mymachine]> chmod a+r /dev/kmem
[mymachine]> ps
Permission denied on /dev/drum blah blah blah.....
[mymachine]> ls -lg /dev/drum
crw-r----- 1 root 7, 0 Mar 5 1993 /dev/drum
[mymachine]> chmod a+r /dev/drum
[mymachine]> ps
