rhnsd
UP2DATE(8) Red Hat, Inc. UP2DATE(8) NAME
rhnsd - a program for quering the Red Hat Network for updates and information SYNOPSIS
rhnsd [OPTION]... DESCRIPTION
rhnsd is a daemon process that runs in the background and periodically polls the Red Hat Network to see if there are any queued actions available. If any are queued, it runs them. rhnsd is typically started from the init scripts in /etc/init.d/rhnsd when it's time to poll the Red Hat Network servers for available updates and actions. The default interval is every 120 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 Red Hat Networks. 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 configure by editing the /etc/sysconfig/rhn/rhnsd config file. This is actually the configuration file the rhnsd init script /etc/init.d/rhnsd uses. -i, --interval Specify the interval that rhnsd should wait between checking the Red Hat Network. Default is 120 minutes, the minimum is 60 minutes. This can also be specified in /etc/sysconfig/rhn/rhnsd -v, --verbose output more information about what rhnsd is doing. -f, --foreground force the rhnds 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 daemons init script. /usr/sbin/rhn_check The external program launched by rhnsd to connect to the Red Hat Network and retrieve any actions that have queued up. /etc/sysconfig/rhn/systemid A certification that authenticates the client machine to the Red Hat Network. Generated via the up2date or rhnreg_ks utility. SEE ALSO
The rhnsd daemon is tightly coupled with Red Hat Network. Visit <http://www.redhat.com/network> for access or to sign up. rhn_check(8), up2date(8), up2date-config(8), AUTHORS
