rhn_check - Check for and execute queued actions on RHN. SYNOPSIS
rhn_check [options] DESCRIPTION
rhn_check is a client program that connects to "Spacewalk Server", "Red Hat Satellite" or "Red Hat Network Classic" and receives queued actions for this particular system. After receiving the actions, rhn_check will then process them, and return the results to Spacewalk. OPTIONS
-v, --verbose Increase the debugging output. --proxy=PROXY Specify an http proxy to use. --proxyUser=PROXYUSER Specify a username to use for an authenticated proxy. This option must be used in conjunction with proxyPassword. --proxyPassword=PROXYPASSWORD Specify a password to use for an authenticated proxy. This option must be used in conjunction with proxyUser. --version Show the program's version number and exit. -h, --help Show a help message and exit. FILES
/etc/sysconfig/rhn/systemid The digital server ID for this machine if the system has been registered onto "Spacewalk Server", "Red Hat Satellite" or "Red Hat Network Classic". This file does not exist otherwise. /etc/sysconfig/rhn/up2date The common configuration file used by RHN client programs. SEE ALSO

RHNSD(8) Red Hat, Inc. RHNSD(8) 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 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 connec- tion 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. 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
