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

SYNOPSIS
       rhn_check [options]

DESCRIPTION
       rhnsd is a background daemon process that periodically polls the Space‐
       walk  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  min‐
       utes.  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.  con‐
       figuration file. This is actually the configuration file the rhnsd ini‐
       tialization script /etc/init.d/rhnsd.  uses.

OPTIONS
       -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.

FILES
       /etc/sysconfig/rhn/rhnsd
	      Configuration settings for  the  rhnsd  daemon's	initialization
	      script.
