User Limits In Linux

[dNetGuru]

Here's the problem !, I want some specific users on my box have higher user limits, to do some specific tasks, however !
I tried using the ulimit command, modifying the /etc/security/limits.conf and /etc/profile ! but I still get the `uname -n` = 100 !

can anyone help help me with this issue or provide me some link and/or instruction to do this type of work, btw I'm using a CentOS 4 box ...

What do you mean? Give examples of the problem you're trying to solve.

Thanks 4 the reply !!

Well let's be more specific, I need a user have it's `ulimit -n` set to 2048 while all other users (except for root) has a 256 value for their open files !

I've edited the /etc/security/limits.conf and added :

ricd hard nofile 2048
ricd soft nofile 1024

and added these lines to the /etc/profile :

if [ `/usr/bin/whoami` = "ricd" ]; then
ulimit -n 1024 2>/dev/null
fi

But I still get the `ulimit -n` 100 for the ricd user

I'm pretty sure /etc/profile gets run as root, so your conditional test will always be false.

Could you just add the ulimit specification to ricd's ~/.bash_profile?

Well, @ first I thought this might be the problem that /etc/profile runs as root, but some time ago I read the cPanel 10 Documention, and there is a block of code (that right now I copied from the documention here) added to /etc/profile !

#cPanel Added Limit Protections -- BEGIN

#unlimit so we can run the whoami
ulimit -n 4096 -u 14335 -m unlimited -d unlimited -s 8192 -c 1000000 -v unlimited 2>/dev/null

LIMITUSER=$USER
if [ -e "/usr/bin/whoami" ]; then
        LIMITUSER=`/usr/bin/whoami`
fi
if [ "$LIMITUSER" != "root" ]; then
        ulimit -n 512 -u 20 -m 200000 -d 200000 -s 8192 -c 200000 -v 200000 2>/dev/null
else
        ulimit -n 4096 -u 14335 -m unlimited -d unlimited -s 8192 -c 1000000 -v unlimited 2>/dev/null
fi
#cPanel Added Limit Protections -- END

So, this tells me /etc/profile does not run as root I think !
Well, I tried adding

if [ -e "/usr/bin/whoami" ]; then
        LIMITUSER=`/usr/bin/whoami`
fi

and then using the conditional sentence with $LIMITUSER, but I still hae the same old problem !

about the ~/.bash_profile idea, I'll check it

Thanks again

--- UPDATE ---

I've tried adding the following line to the .bash_profile :

ulimit -n 1024 2>/dev/null

But I get the same result !!!
