# Chapter 5. Red Hat Network Registration Client

Before you begin using Red Hat Network, you must create a username, password, and System Profile. The Red Hat Network Registration Client walks you through this process.

| Warning
| Only systems running Red Hat Enterprise Linux 2.1 need to use the Red Hat Network Registration Client before starting the Red Hat Update Agent. Systems running Red Hat Enterprise Linux 3 and later have this registration functionality built into the Red Hat Update Agent. After registering your system, refer to Chapter 2 Red Hat Update Agent for instructions on starting the Red Hat Update Agent.

# 5.1. Configuring the Red Hat Network Registration Client

To start the graphical interface for configuring the application to connect through an HTTP proxy server, type the following command at a shell prompt:

    rhn_register --configure

The window shown in Figure 5-1 appears.

Figure 5-1. Red Hat Network Registration Client Configuration

To start the command line version, use the command:

    rhn_register --nox --configure

It has more configuration options than the graphical version.

You will be presented with a list of options and their current values:

    0.  enableProxyAuth    No
    1.  noSSLServerURL     http://xmlrpc.rhn.redhat.com/XMLRPC
    2.  oemInfoFile        /etc/sysconfig/rhn/oeminfo
    3.  enableProxy        No
    4.  networkSetup       Yes
    5.  httpProxy
    6.  proxyUser
    7.  serverURL          https://xmlrpc.rhn.redhat.com/XMLRPC
    8.  proxyPassword
    9.  debug              No

    Enter number of item to edit <return to exit, q to quit without saving>:

Enter the number of the item to modify and enter a new value for the option. When finished changing your configuration, press <KEYCAP >[Enter]</KEYCAP > to save your changes and exit. Press <KEYCAP >[q]</KEYCAP > and then <KEYCAP >[Enter]</KEYCAP > to quit without saving your changes.

The most common options configured are `enableProxy` and `httpProxy` to enable a proxy server. To enable a proxy server, change the value for `enableProxy` to `Yes` and the value of `httpProxy` to the name of the proxy server and port number in the format HOST:PORT. For example, to use the proxy server squid.mysite.org on port 3128, you would change the value to `squid.mysite.org:3128`.

If you require a proxy username and password, set `enableProxyAuth` to `Yes` to enable username/password authentication for the proxy, and set `proxyUser` and `proxyPassword` to the appropriate username and password for the proxy.

To bypass SSL, change the protocol for `serverURL` from `https` to `http` in the `/etc/sysconfig/rhn/rhn_register` file.
