After installing and configuring the RHN Proxy Server, install the SSL CA certificate contained in the rhns-ca-cert RPM package. If you used the RHN Proxy Server Installation Program as described in Chapter 5 Quick Start Guide, go to http://your_rhn_proxy_server.example.com/pub/ in a Web browser on the client system, download the RPM, and install it.
You also need to install and configure the Red Hat Update Agent (up2date) on the client systems. Systems running versions of Red Hat Linux older than 8.0 will also need to install and configure the Spacewalk Registration Client (rhn_register). The registration functionality is included in the Red Hat Update Agent starting with RHL 8.0 and will appear when launched on unregistered systems. To force its launch, enter this at the command line:
up2date --register |
If you prefer graphical versions of these tools, install up2date-gnome and rhn_register-gnome, if necessary. After installing the software, configure it to connect to the RHN Proxy Server, instead of the default Spacewalk Server. Refer to the following sections for precise instructions.

You must install the latest versions of these client applications. They can be obtained via RHN. After registering, run the command up2date up2date before updating any other packages. |
To configure the Red Hat Update Agent on the client systems connecting to the RHN Proxy Server, edit the values of the serverURL and noSSLServerURL options in the /etc/sysconfig/rhn/up2date configuration file (as root). Replace the default Spacewalk URL with the URL for the RHN Proxy Server. For example:
noSSLServerURL[comment]=Remote server URL without SSL noSSLServerURL=http://your_rhn_proxy_server.com/XMLRPC serverURL[comment]=Remote server URL serverURL=https://your_rhn_proxy_server.com/XMLRPC |
You can also use the command line tool up2date --configure to configure the Red Hat Update Agent to use the RHN Proxy Server.
If you are using the RHN Package Manager to update local packages, you must go to the RHN website to subscribe the system to the private channel.

Warning |
---|---|
The httpProxy setting in /etc/sysconfig/rhn/up2date does not refer to the RHN Proxy Server. It is used to configure an optional HTTP Proxy for the client. With the Spacewalk Proxy solution in place, the httpProxy setting must be blank (it should not be set to any value). |
For further instructions on using the Red Hat Update Agent, refer to the Spacewalk User Reference Guide available at http://www.redhat.com/docs/.
