Updating system software


sipXecs provides a web frontend in sipXconfig to CentOS's updating software YUM (Yellowdog Updater, Modified). Software updates are accessed with the Software Updates menu item in the System menu. Doing so will display the following page:

The page is refreshed by default after every 10 seconds. Unchecking the Refresh box will disable the automatic update. Clicking on the refresh time will allow the administrator to change the interval if desired.

A manual check for updates can be run by clicking on the Check for updates button.

If updates are available, the option to install them will be made available. If other YUM repos are desired, they can be added to the /etc/yum.repos.d directory. Information on YUM can be found at http://yum.baseurl.org.
