Hello,
We are running Tru64-unix v4.0E on alpha servers GS140.
We want to reduce resource limits (cpu time, memory....) soft and hard
at any interactive login.
So we have added in /etc/profile commands 'ulimit -S ...' and 'ulimit -H...'.
The problem is that 'ulimit -H..' seems to be allowed only for superuser
even for decreasing current limit.(ulimit is here the imbedded shell command)
As /etc/profile is executed in behalf of the user's login, we are only
able to reduce soft limits. And a malicious user can increase them quickly.
Question: how to reduce hard limits at login time for sh and ksh users.
PS: it is OK for csh users.
Thanks ,
