set ulimit

[premabodh]

Hi All,

I tried setting ulimit but everytime I restart the system it gets reset to default value of 1024 i.e. command ulimit -n gives 1024.

Tried setting in /etc/security/limits.conf like this:
@user soft nofile 5000

also adding ulimit -c 5000 and ulimit -n 5000 in /etc/profile but not working.

also did
$sudo ulimit -n 5000
giving following error:
sudo: ulimit: command not found


Please let me know how to set this value in ubuntu 6.06 LTS. I am still using this version.

Thanks and Regards,
Vikash Anand..

Try adding it to .bashrc:


gksudo gedit .bashrc


ulimit -n 5000

You must exit from your terminal and re-login for the change to take effect.

Well then remove the line from .bashrc. See this thread:

Hi,

I have googled and also found this solution and have tried it but is not working. After restarting machine when i try ulimit -n it still shows 1024.

I am not setting so high values as stated in the URL you provided. I am setting it to 4096 only which is not very high.

I figured it out you need to sudo su drop into root and set it


ulimit -n 4096

Never mind as soon as you exit root it defaults back to 1024.
