I have a script that needs to extract certain information form the /proc/net/ip_conntrack file once in a while. I do not wish to run this script as the root user.

Default permissions for the file is:

$ ls -lah /proc/net/ip_conntrack
-r--r----- 1 root root 0 2010-03-28 12:18 /proc/net/ip_conntrack

I can change it with:

sudo chmod o+r /proc/net/ip_conntrack

But that does not stick after a reboot. Is there some configuration file for file-permissions in the /proc directory in Ubuntu Server 9.10? Or do I just have to stick a chmod line in some startup script?

/proc is a virtual filesystem that resides only in memory. You should put your chmod line in a start up script. – Jimmy Hedman Mar 29 '10 at 17:15

it looks like you can safely stick the chmod command in rc.local (http://www.openbsd.org/cgi-bin/man.cgi?query=rc.local&sektion=8)

Will do. I just thought there might be some configuration files for the permissions of the virtual /proc file-system. No reason to loose sleep over this, thanks. :) – Bjarke Freund-Hansen Mar 30 '10 at 7:50
