Figure 4.2. HTTP Proxy Configuration

If your network connection requires you to use an HTTP Proxy Server to make HTTP

connections, on the Proxy Configuration screen, type your proxy server in the text field with

the format HOST:PORT. For example, to use the proxy server http://squid.mysite.org on port

3128, enter

squid.mysite.org:3128

in the text field. Additionally, if your proxy server requires

a username and password, select the Use Authentication option and enter your username and

password in the respective text fields.

Tip

To run the configuration wizard again, right-click on the applet, and select

Configuration.

Your preferences are written to the

.rhn-applet.conf

file in your home directory. The Red Hat

Network Alert Notification Tool also uses the system-wide configuration file

/etc/sysconfig/rhn/rhn-applet

. The setting for server_url should be set to your satellite

server. For example:

server_url=http://YourRHN_Satellite.com/APPLET
