I tried to look this up in a Google search, but no luck.  Can someone
please explain to me what the concept of Runlevels is?  I am using FC4,
and I was playing around with the System Settings\Server
Settings\Services tool to get my Samba to autostart.  There are 3
categories of Runlevels for every service... 3, 4 and 5.  What do these
mean?  Should I select 3,4 and 5 for Samba?

Thanks in advance.

Runlevel 0: shutdown of system. Not turned off.
Runlevel 1: single user mode, commonly used to repair things or manage
filesystems.

Runlevel 2: multi user mode with low number of services. I use it only
check changes in network settings.

Runlevel 3: multi user mode with X-Windows services. Normal mode for
servers.

Runlevel 4: not implemented by most Linux distributions.

Runlevel 5: multi user mode with X-Windows services. Normal mode for
Workstations and Desktops. For servers I only use it if I need to use a
graphical tool or a webbrowser.


Hope to have explained a little bit.

For samba I would say use the default:
chkconfig smb on

Look for the settings by:
chkconfig --list smb

On my system it results in:
smb             0:off   1:off   2:on    3:on    4:on    5:on    6:off


Kind regards,

Jan, excellent explanations.  Thanks very much for your quick response.

Runlevel 6: reboot: should only have stopscripts, so in:
chkconfig --list servicename you should see 6:off

Just to complete the explanation.
