You can specify @reboot instead of the time and date settings in
crontab, which is probably the most straightforward way of doing this

Alternatively, you can make /etc/rc.local executable (sudo chmod +x
/etc/rc.local) and then add *before the exit 0 line* « sudo -u
username command » -- the crontab method seems neater to me though.

The only issue you might get with the crontab version is if it runs
before the network is initialised and shoutcast expects an interface
to be there. You shouldn't have this problem with rc.local because it
won't run until after all the other init scripts, but it's probably
worth just trying the crontab method first.

Icecast is the same code as shoutcast but open source. I'm not sure if it
supports mp3 out of the box with Ubuntu but it does eventually (I haven't
used it for years to be honest).

Thanks Simon and Neil,

I've used Icecast in the past, seems much better than Shoutcast as far 
as documentation goes.  I'm not sure why he specifically needs Shoutcast.

I don't suppose you know if Icecast is compatible with Shoutcast is it? 
  (I mean for streaming to the server, at the moment I'm using Winamp 
with the Shoutcast DSP plugin to send the audio to the server and then 
the Gnome Movie Player app to play the stream).

You can set the user and group in the security stanza of the configuration
file. You can then launch it from an init script and it should run as the
user.

Running it from cron is also valid, but you run a script every minute (or
whatever interval you want) that checks for the pid file or running process
and restarts the server if it can't find one or the other.

Icecast is better documented and more actively supported than shoutcast on
Linux - the old shoutcast documentation doesn't seem to exist anymore.

Write an init script that uses sudo or su to run the shoutcast daemon
as another user?

You shouldn't need to enter a password if you run su as root, IIRC.

[ubuntu-uk] Running daemon at startup as another user

[Rob Beard]

Hi folks,

I'm trying to setup Shoutcast on a VPS server for a mate of mine as a 
favour.  The VPS server is running Ubuntu 8.04 AMD64.

Now I gather from reading up, it is recommended that the shoutcast 
daemon is run as a user rather than root (presumably for security purposes).

The thing is, I can't figure out how to do it.  At first I thought of 
creating an init script, but presumably it'll run as root?

I also thought about cron, but I guess that would require me to enter a 
start time (so if the server goes down say in the middle of the day then 
it'll have to wait until the start time in the crontab?)

So I wondered if there was any way of running the shoutcast daemon as 
another user basically from when the machine boots?
