## How to start the daemons at boot time

| Note
This section talks about how to get the Big Sister daemons started each time the box is rebooted. This is handy for ensuring the agents are always running.

Under Windows use the Control Panel / Service Manager to tell your system which Big Sister services it should startup on boot. See section 1.2 for determining what services should run on which systems.

With Unix the startup of Big Sister daemons is a little different. There is a perl script named {ROOT}/bin/bb_start meant to work like a System V init script, thus running

`bin/bb_start start` will start up the Big Sister daemons while`bin/bb_start stop` will shut them down and`bin/bb_start restart` will restart Big Sister.

Since the init directories should only contain shell scripts and no perl scripts a little shell script has been installed in your init directory which is basically a wrapper for the above mentioned perl script. Therefore you can create the necessary links in your rc*.d directories to the wrapper script `/etc/init.d/bigsister`. If you are running Big Sister on RedHat Linux you can use the `chkconfig` command to enable / disable Big Sister.

bb_start will look at the config files in the `/etc/bigsister` directory for deciding whether it should act like an agent or a server.
