6.1. Managing the Proxy Service
Since the RHN Proxy Server consists of a multitude of individual components, Red Hat provides a
script called rhn-proxy, that allows you to stop, start, or retrieve status on the Proxy.
/usr/sbin/rhn-proxy start
/usr/sbin/rhn-proxy stop
/usr/sbin/rhn-proxy restart
/usr/sbin/rhn-proxy status
Use the rhn-proxy command to shut down and start the entire RHN Proxy 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
files provide invaluable information about the activity that has taken place on the device or within the
application and can be used to monitor performance and ensure proper configuration. See
"Log Files"
for the paths to all relevant log files:
Component
Apache Web server
Squid
RHN Proxy Broker Server
RHN SSL Redirect Server
Red Hat Update Agent

6.3. Questions and Answers
This section contains the answers to the most frequently asked questions regarding installing and
configuring an RHN Proxy Server solution.
Q:
After configuring the RHN Package Manager how can I determine if the local packages were
successfully added to the private RHN channel?
A:
Use the command rhn_package_manager -l -c "name_of_private_channel" to list
the private channel packages known to the RHN Servers. Or visit the RHN Web interface.
After subscribing a registered system to the private channel, you can also execute the command
up2date -l --showall on the registered system and look for the packages from the private
RHN channel.
