If your network connection requires you to use an HTTP Proxy Server to make HTTP connec-
tions, on the Proxy Configuration screen, type your proxy server in the text field with the format
http://HOST:PORT. For example, to use the proxy server http://squid.mysite.org on port 3128, enter
http://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 pass-
word in the respective text fields.
Tip

automatically generated by the application.
You can also configure the
Red Hat Network Alert Notification Tool not to list specific packages.
To configure which packages to ignore, click on the applet, and select the
Ignored Packages
