Chapter 5: General System Configuration

The second category on the Webmin tab bar is System. Clicking it will allow you to edit such system features as: Bootup and Shutdown behavior, Disk Quotas, Filesystems, Manual Pages, NFS Exports, Processes, Cron Jobs, System Logs, and more. Figure 5-1 shows the options available on a Linux system (specifically, a server that’s running Red Hat Linux).

Bootup and Shutdown

Clicking Bootup and Shutdown brings you to a page of bootup options. In the case of a Red Hat system, it provides access to all of the init scripts found in /etc/ rc.d/init.d. Similarly, on a Solaris system the scripts are located in /etc/init.d. Clicking on any of the script names will provide the ability to edit, start, stop, and delete the init script. Usually, each init script provides functions to start, stop, and restart system services such as Sendmail, named, and Apache, as well as perform basic system initializations such as setting up network devices and routing tables. An easy way to add a new service or command to the system startup routine, if it does not have an init script, is to add it in /etc/rc.d/rc.local or /etc/rc.local.

Also on this page you’ll see the Reboot and Shutdown buttons. They do just what you would assume, after a confirmation screen.
