Use "nice" as other user than root...
 
Hello,

I tried to change priority of process with "nice" command, but function return me a error because only root can make it. The same problem if I try to do it by code:
Code:
        memset(&schedp, 0, sizeof(schedp));
        schedp.sched_priority = par->prio;
        sched_setscheduler(0, SCHED_FIFO, &schedp);
is there a way to change priority of process or thread with user different than root???

Best regards.

I don't imagine that would be a good idea.
Changing process priority would be an administration task right - so ask the administrator.

You could always add nice to sudo for all users with no password... Just an option.

Hello Simon,

you are right, it is not a good idea.
This doubt is only to make a test, and I am administrator of machine, so do not worried about it.

Then, is it possible??

Best regards

Then you are talking about privilege escalation, a whole different ball game.
How easy it is depends on how your system is set up. What is your concern?

@arkane: for goodness sake tone down your sig. Nobody will thank you when you're yelling in their faces.
