RE: Automatically configure ulimit -SOLVED
AFAIK hard means that is the absolute max amount of (in my case) open files soft means that the user will default to that amount. So fo example my requirement was that the user account would have 8096 files open, rather than setting the hard to 8096 and then requiring that the user "ulimit -n 8096" from the default 1024, I put in the soft setting to 8096. When I log on as a user and type ulimit -a I get the desired result.

Great, thanks. Now can anyone explain the difference between "hard" and "soft" limits?

RE: Automatically configure ulimit -SOLVED
There is a way to configure this. see /ect/security/limits.conf This is handled by a PAM during authentication. -Original Message- From: Richard Wilson Sent: Friday, March 08, 2002 1:57 PM To: '[EMAIL PROTECTED]' Subject: RE: Automatically configure ulimit Ben: I'm trying to increase the number of open files with "ulimit -n ", this operation requires super user privilege.
