I'm stuck really badly on this... even though my /etc/security/limits.conf has the necessary lines that should allow me to change my ulimit, I still can't do it. baloo@ursine:~$ ulimit -n 4096 bash: ulimit: open files: cannot modify limit: Operation not permitted baloo@ursine:~$ ulimit -Sn 1024 baloo@ursine:~$ ulimit -Hn 1024 What am I doing wrong or failing to check? -- Paul Johnson Email and IM (XMPP & Google Talk): baloo@ursine.ca Jabber: Because it's time to move forward http://ursine.ca/Ursine:Jabber
