Getting ready

You will need the address of the proxy server you are trying to connect to, including the username and password, if one is required.

You should confirm that Raspberry Pi is already connected to the network and that you can access the proxy server.

Use the ping command to check this, as follows:

ping proxy.address.com -c 4  

If this fails (you get no responses), you will need to ensure your network settings are correct before continuing.
