How do I verify that service is turned on in xinetd under Fedora or Red Hat Linux?

Q. I am running Fedora Linux version 4.0 server. Couple of services run under xinetd. Now how do I verify that service is turned on in xinetd?

A. You can use command line tool called chkconfig or text based GUI tool called ntsysv. For example see if service foo:

# chkconfig --list foo

Output:

foo          off

As you see service foo is off, to turn on type command:

# chkconfig foo on
# chkconfig --list foo

Output:

foo           on

It is recommended that you use ntsysv, which is graphical tool and works on remote ssh session.
