Changing a users nice privileges

Alan Edwards — Tue, 29 Oct 2002 18:57:58 GMT

Does anyone know how to allow a user to reduce the nice value of a command he wants to run?
The user accounts come from NIS.

I did, it just mentioned privileges, but not how to change them.

nice - run a new process at the given priority
renice - change the priority of a process that's already running

From man renice
-To reduce the system nice value of a process, or to set it to a value less than 20 (with a negative newoffset), a user must have appropriate privileges.

man privgrp

RTPRIO -

Hi Chris,

Yes, but how do you give the appropriate privileges?

Do a man on nice. There is a priority_change option that gives priveledges to other users.

The only way I know is that the user be superuser or be given superuser privileges thru sudo or restricted SAM.

Hi,

The only way a user can increase priority fo their process is:

1) sudo (preferred)
2) SUID on the nice (at eceution) or renice (afterwards) command (riskier)

set
man 1m setprivgrp

essentially, you place someone in a group, then you delegate privilege to that group:

e.g.
/etc/group

fred:fredsgrp

#ll /etc/privgroup
#setprivgrp fredsgrp RTPRIO
