6.1. Managing the Proxy Service
Since the RHN Proxy Server consists of a multitude of individual components, Red Hat provides
a master service that allows you to stop, start, or retrieve status from the various services in the
appropriate order:
rhn-proxy
. This helper service accepts all of the typical commands:
service rhn-proxy start
service rhn-proxy stop
service rhn-proxy restart
service rhn-proxy status
Use the
rhn-proxy
service to shut down and bring up the entire RHN Satellite Server and retrieve
status messages from all of its services at once.
6.2. Log Files
Virtually every troubleshooting step should start with a look at the associated log file or files. These
provide invaluable information about the activity that has taken place on the device or within the
application that can be used to monitor performance and ensure proper configuration. See Table 6-1
for the paths to all relevant log files:
Component Log File Location

1. After configuring the RHN Package Manager how can I determine if the local packages were
successfully added to the private RHN channel?
Use the command

to list the pri-
vate channel packages known to the RHN Servers. Or visit the RHN Web interface.
