[SOLVED] Non-root renice

mwkemo · 08-30-2009, 06:38 PM

Hello,

having problem with renice. I wont to renice users process from +19 to +13. I can renice from higher priority to lower but not reverse. I did try to add to /etc/security/limits.conf line with "* - nice -19" and "* - renice -19" but this is not working.
On my other box with same setup renice from lower to higher process is working, but the other box is Etch and the one with problem is Lenny. Any changes made for renice persmissions?

Help please?

From the renice(1) manpages:

Code:

Users other than the super-user may only alter the priority of processes
they own, and can only monotonically increase their ‘‘nice value’’ within
the range 0 to PRIO_MAX (20).

That's on my Fedora box. I'm surprised what you are describing is working at all on one of your systems.

I'd be looking at the Debian changelogs ... or compare
the man-pages for renice on both.

I just needed to start process with higher priority, after that i can renice to lower with no problems. On working system this was done within start script. I have forgotten that I changed start priority of process.

Anyway, Thanks for help
