Red Hat Enterprise Linux Support Information

Description:

RHN Update Client Configuration

Red Hat Network is a complete systems management platform for Linux. It's built on open standards and uses a simple, Internet-based graphical interface. It can provide system updates, management, and monitoring for large sets of systems. An RHN Proxy Server is a service deployed within a local network with advanced Red Hat Network functionality, such as a package-caching mechanism for reduced bandwidth usage and customizable channels enabling custom package deployment.

The University has purchased a site-license for Red Hat Enterprise Linux which includes access to a local Red Hat Network proxy. To use this service you will need to modify the configuration file for the up2date program on your Red Hat Enterprise Linux (RHEL) system. You must have rights to edit this file, either with the root user account or by using the sudo command.

These instructions are specific to RHEL 3. If you are using an older version you may need to make additional changes. Please consult the Red Hat Network manuals for your version of RHEL and/or up2date for details.

Issue the following command as the root user:

wget -q -O - http://rhn.uta.edu/pub/bootstrap/bootstrap-rhn.sh | /bin/bash

While executing the above command completely automates the process of configuring your system, it should be mentioned that you'll be running commands on your system directly from the internet, which could be dangerous. It's recommended that you follow the steps listed below to configure your system.

Issue all commands as the root user. These steps will configure your RHEL 3 system to receive updates from our local proxy server. You'll be installing an SSL certificate for rhn.uta.edu on your system; this step lets your system trust the RPM packages it receives from the proxy server. Next you'll modify your /etc/sysconfig/rhn/up2date file, the configuration file for up2date, with settings to use the proxy server. Lastly, you'll configure your system to trust packages signed by Red Hat.

rpm -ivh http://rhn.uta.edu/pub/rhn-org-trusted-ssl-cert-1.0-1.noarch.rpm

perl -p -i -e 's/xmlrpc.rhn.redhat.com/rhn.uta.edu/g' /etc/sysconfig/rhn/up2date

perl -p -i -e 's/^sslCA/#sslCA/g;' /etc/sysconfig/rhn/up2date

echo "sslCACert=/usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT" >> \
/etc/sysconfig/rhn/up2date

rpm --import /usr/share/rhn/RPM-GPG-KEY
