istributions use different mechanisms for starting and stopping system processes, the
easiest way to do this is to send the HUP signal to the running xinetd process. To
ocate the process ID of the xinetd process that is currently
running on your system using the ps (process status) command, as in the following
fter executing this command, the TFTP server will be started on your system in

The example line shows the xinetd process ID number, in the fourth whitespace-
separated field (2292 in this example), which is the information that you will need to
restart the process. After collecting this information, you can cause the xinetd
rocess to reread its configuration files by executing a command like the following: p

If your system is running a Linux distribution such as Red Hat Linux that starts and stops sy
