Establishing a VPN connection to the Lab

VPNs

All recent Windows versions allow you to create a "Virtual Private Network" to the Lab's Windows domain. This allows you to direct traffic into the Lab's protected network as a "trusted user"; you have to type your password to authenticate yourself.

Preparing

You need:

  • A Lab account, and to be a member of the unix group VPN. By default membership of this group is not given when accounts are created. You should therefore request access to the VPN by mailing win-admin.
  • A connection to the internet already established on your computer. (Any internet connection will do: it is possible, though not very useful, to connect from a managed Lab machine via a VPN.)

You don't need a privileged account on your computer.

Controlling the connection

The connection is accessible via the task-bar icon (if it's currently active), via the Start menu, or via "Network and Dial-up Connections", from the Control Panel.

Disconnect the session by right-clicking on any of the items (it doesn't matter which), and selecting "Disconnect".

Reconnect the session by right-clicking any item you can find, and selecting "Connect". You will have to type your password again.
