Do you have a Notebook running Linux?
Do you frequently use it in different network environments with different proxy configurations?
Are you sick of frequently reconfiguring all the applications that have their own proxy settings like the web browser, the Java IDE, the desktop and the applications that uses its settings, the other desktop environment that uses other settings... and so on?
If your answer to these questions is yes, yes and yes then read on. The solution I present here allows you to configure proxy settings in any of your applications just once and will even change the proxy settings automatically as soon as you connect your laptop to a network.
