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.

6.3.1.	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 `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.
6.3.2.	How can I determine whether the clients are connecting to the Squid server?
	The `/var/log/squid/access.log` file logs all connections to the Squid server.
6.3.3.	The Red Hat Update Agent on the client systems does not connect through the RHN Proxy Server. How can I resolve this error?
	Make sure that the latest version of the Red Hat Update Agent is installed on the client systems. The latest version contains features necessary to connect through an RHN Proxy Server. The latest version can be obtained through the Red Hat Network by issuing the command `up2date up2date` as root or from http://www.redhat.com/support/errata/. Also, be advised that since the RHN Proxy Server acts as a caching mechanism for RHN, the `httpProxy` setting in `/etc/sysconfig/rhn/up2date` on client systems is redundant and probably unnecessary. The RHN Proxy Server is an extension of Apache. See Table 6.1, “Log Files” for its log file location.
6.3.4.	My RHN Proxy Server configuration does not work. Where do I begin troubleshooting it?
	Make sure `/etc/sysconfig/rhn/systemid` is owned by root.apache with the permissions 0640. Read the log files. A list is available at Table 6.1, “Log Files”.
