rhnsd - A program for querying the Spacewalk server for updates and information.


rhn_check [options]


rhnsd is a background daemon process that periodically polls the Spacewalk server to see if there are any queued actions available. If any are queued, rhnsd will execute those actions.

rhnsd is typically started from the initialization (init) scripts in /etc/init.d/rhnsd. when it's time to poll the Spacewalk server for available updates and actions. The default interval is every 240 minutes. The minimum polling interval is 60 minutes.

To check for updates, rhnsd runs an external program called rhn_check. This is a small application that actually makes the network connection to Spacewalk.

The rhnsd daemon does not listen on any network ports, nor does it ever talk to the network directly. Any network activity is done via the rhn_check utility.

rhnsd can be configured by editing the /etc/sysconfig/rhn/rhnsd. configuration file. This is actually the configuration file the rhnsd initialization script /etc/init.d/rhnsd. uses.


-i, --interval
Specify the interval that rhnsd should wait between checking the Spacewalk. Default is 240 minutes, the minimum is 60 minutes. This can also be specified in /etc/sysconfig/rhn/rhnsd
-f, --foreground
force the rhnsd process to run in the foreground instead of automatically backgrounding itself, as it does by default.
