This section contains the answers to the most frequently asked questions regarding installing and configuring an RHN Proxy Server solution.
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.
A: The /var/log/squid/access.log file logs all connections to the Squid server.
A: Make sure 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 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 for its log file location.
A: Make sure /etc/sysconfig/rhn/systemid is owned by root.apache with the permissions 0640.
