Hi I have an Apache webserver set up on a Fedora Core 1 machine and have been using gnump3d to serve mp3s over my network.

The problem is that if there's a power cut or something and the machine shuts down, I have to manually log on and start gnump3d again. I decided to fix it yesterday after another power cut and tried adding

/usr/bin/gnump3d

to /etc/rc.local (I think)

It worked and gnump3d was started but the problem is that it was started by user 'nobody' (checked using ps aux).

I need to have gnump3d started by user 'stu' for example so is there a way to do this perhaps using 'su' although I don't want a shell opening.

Thanks, Stu

su -c /usr/bin/gnump3d stu

Try this

...as deduced from info in this page:
http://www.ss64.com/bash/su.html
and check here too:

Thanks for the super-fast response. I did have a look through the manual entry for su but it sounded to me like the -c option opened the shell and then sent a command to it. The explanation at http://www.ss64.com/bash/su.html seems much clearer, I think this is exactly what I need.

I'll give it a try when I get in tonight - and let you know.

The su command didn't work properly, well it worked but it started another process (su) as well as the gnump3d process. I checked the sudo command and the following seems to have worked ...

sudo -u stu -b /usr/bin/gnump3d

Thanks for the help GrapefruiTgirl.

Take it easy, Stu

Hey cool, glad you figured that out; I learned something as well
Take care.
