Iis – Does changing log file location in IIS need a restart of websites

There are permissions management setups that don't require you to use sudo -- you could give the user running the script access to the group that owns /var/log/messages (adm, on my laptop here). Alternately, use NOPASSWD in the sudoers entry for the script, so that you don't have to store a password in the script.

If you're really dead-set on letting the world see what's in /var/log/messages (and I'd strongly recommend against it -- there really can be private stuff in there) then what's setting your permissions back to default is probably logrotate, so check out your logrotate config and find the stanza that's doing your /var/log/messages rotation and change it.

Didn't find the log but managed to solve the problem by looking at the above snippet.
