I'm trying to set the open files value to 4000 on a SLES 9 system.

Current values:

Code:

ulimit -n
1024

I can set it using this:

Code:

ulimit -n 4000
ulimit -n
4000

But this obviously sets it only for the shell session where I run the command to set it. I want to set this to 4000 for all time.

What I've tried so far:

Extract from /etc/security/limits.conf:

Code:

*       hard    nofile  4000
*       soft    nofile  4000

In the sshd and login files in /etc/pam.d,

Code:

grep pam_limits.so login sshd
login:session  required       pam_limits.so
sshd:session  required       pam_limits.so

What am I missing here? I even tried a reboot (I don't know if it was required, but the server isn't live, so I can experiment a bit :P)
