Here is a simple script to start bitten-slave as a daemon on Ubuntu. The example file below should be saved as 'bitten-slave' in '/etc/init.d'. This has been tested on Ubuntu Hardy, however should run from any system with only minimal changes. You will need to change the DAEMON_ARGS variable to contain a URL which reflects your server.

To start the daemon manaually run the following.

{{{
sudo /etc/init.d/bitten-slave start
}}}

Likewise you can stop the daemon with

{{{
sudo /etc/init.d/bitten-slave stop
}}}

To enable the script so the bitten slave will automatically be started at boot time and stopped at shutdown make the script executable and enable it.

{{{
sudo chmod 755 /etc/init.d/bitten-slave
update-rc.d bitten-slave defaults
}}}

=== Ubuntu 12.04 LTS ===

After installing the ''trac-bitten-slave'' package you can use the script but you have to change:
{{{
DAEMON=/usr/local/bin/$NAME
}}}
to:
{{{
DAEMON=/usr/bin/$NAME
}}}
