Chkconfig
From Attie's Wiki
chkconfig is used to configure the system services.
Note: this will not start or stop the service... you must use the service's standard method if you wish to start/stop it now
Use it in the following ways:
To make samba run at boot up:
$ chkconfig --level 2345 smb on
Omitting the --level parameter will apply the changes to all levels.
To disable the samba service:
$ chkconfig smb off
To show the list of services:
$ chkconfig --list
