I am installing Ubuntu operating system on to a open source hardware Soc(system on chip) i.e beagleboard-xm. While I am booting it I need to configure the network. I have to enter an HTTP proxy information in the standard form. It prompted to type in the standard form as "http://[[user] [
ort]/" . But I am not able to understand this standard form. I request you to please explain me the standard form in detail.
