SSH Client

Here are two possible clients to log into the machine

If you are on a Mac, then open Terminal and you can access SSH from the console.

SSH into the Box

Now that you have an SSH, copy the information from VLC to log into your newly reserved box. DO NOT BLINBLY COPY the details below as your username and password will be different.

$ ssh aforward@

You will be asked about the authenticity of the host, to proceed you will have to say “yes”
