DESCRIPTION

       rhn_check  is  a  client  program that connects to the Red Hat Network backend servers and retrieves information associated with the queued
       actions for this particular system. This script reads the digital server ID from /etc/sysconfig/rhn/systemid and uses that to identify  the
       machine to the Red Hat Network. Upon successfull authentication, rhn_check will start processing the queued actions sequentially.

       The following types of actions are currently processed by rhn_check:

       action type	 description

       ()																	       ()

       refresh		 This action will refresh the hardware or software profiles of this
			 machine with Red Hat Network. This fucntion is called as
			 refresh(hardware) or refresh(rpmlist)
       new_systemid	 This action is used by the RHn Backend to update the Digital
			 system ID of this machine with a new one.
       update_packages	 This action will trigger rhn_check into running a package
			 update for a list of packages queued from the Red Hat Network.
			 rhn_check will use modules from the up2date client to download
			 the packages, solve dependencies and install the on the system.

FILES

       /etc/sysconfig/rhn/systemid  The digital server ID for this machine if the system has been registered onto Red Hat Network.  This file does
       not exist otherwise.
