SYNOPSIS

DESCRIPTION

15       rhnsd is a background daemon process that periodically polls the Space‐
16       walk  server  to  see if there are any queued actions available. If any
17       are queued, rhnsd will execute those actions.
18
19       rhnsd is typically started from the initialization  (init)  scripts  in
20       /etc/init.d/rhnsd.   when  it's  time  to poll the Spacewalk server for
21       available updates and actions. The default interval is every  240  min‐
22       utes.  The minimum polling interval is 60 minutes.
23
24       To  check for updates, rhnsd runs an external program called rhn_check.
25       This is a small application that actually makes the network  connection
26       to Spacewalk.
27
28       The rhnsd daemon does not listen on any network ports, nor does it ever
29       talk to the network directly. Any network  activity  is  done  via  the
30       rhn_check utility.
31
32       rhnsd  can be configured by editing the /etc/sysconfig/rhn/rhnsd.  con‐
33       figuration file. This is actually the configuration file the rhnsd ini‐
34       tialization script /etc/init.d/rhnsd.  uses.

OPTIONS

38       -i, --interval
39              Specify the interval that rhnsd should wait between checking the
40              Spacewalk. Default is 240 minutes, the minimum  is  60  minutes.
41              This can also be specified in /etc/sysconfig/rhn/rhnsd
42
43       -f, --foreground
44              force  the  rhnsd  process  to  run in the foreground instead of
45              automatically backgrounding itself, as it does by default.
