Call Of Duty Server; User To Run?

Message

I've been messing around just trying to get a Call Of Duty United Offensive server up for my home lan. Suprisingly, it was very simple. I'm wondering though, if I was to ever make this a public server how I would actually run the server as another user besides root. If COD ever got exploited I don't want people having root access. So I guess I'd want to run the game as maybe user 'nobody'. But doesn't this user have low priority? I'd want the application to run with the highest priority.

So, what are your suggestions? I guess what I'm asking is, how do you run a process as an unprivelaged user with high priority.

Thanks in advance.

Yes I'm aware of the nice command. I'm also aware of the sudo command but, as the nice man pages state, non root users can only lower the priority. I'm thinking if I run this command it will work:

Code: Select all

# nice -n -20 sudo -u nobody /opt/call_of_duty/coduo_lndxed

I'll have to try it out when I get home.

The above command does not work because, for some reason, it tries to create /root/.callofduty every time its run. Anybody know why this happens or how to change the path?

You can use

Code: Select all

bash# ps aux | grep coduo_lndxed

to find the process ID of you're call of duty server.

Then you can use

Code: Select all

sudo renice -20 [ProcessID]

to give you're process higher priority after it's started.

Not sure how to make it run as the "nobody" user, but this might help you change the priority once you get that working
