Thanks. But why do some commands require service service-name command (like sshd) where postfix works without the service command in front
of
it?
you still do not realize the difference between start/stop/restart and enable/disable a service, they *all* behave identically
some are enabled by default after install, some are not __________________________________
service *whatever* start service *whatever* restart service *whatever* stop
chkconfig *whatever* on chkconfig *whatever* off __________________________________
start/stop/restart acts *now* on/off acts at boot
please read some basic documentations!

I do understand that.
But why can you do
postfix stop/start
but not
sshd stop/start. With sshd you need to use service sshd stop/start. It seems inconsistent.

Services are also executables. The name of the service and the name of the executable often but not always match. Utilities like `service` and `chkconfig` work with the init system to manage services. You can also invoke the executables by hand from the command line, but it would get tedious. The initscripts control the arguments an executable is given at start.
`service` is also an executable. It takes different arguments from other executables, primarily the name of the service to act on and the action to be taken. You don't expect different utilities to have identical command syntax, because they do different work.
