Apple Screen Sharing

All macOS Apple desktop systems have Apple Screen Sharing enabled which allows you to remotely access a Apple desktop system environment.

Open a ssh tunnel via the ssh gateway on port 5900 before you can connect to the systems. This no longer work through the Physics VPN.

If you wish to open a ssh tunnel to use Screen Sharing on your Apple desktop system do the following:

Set up the SSH gateway into the Physics department following the instructions here
Open Terminal window, from an Apple system this is in the /Applications/Utilities/ folder.
In the Terminal window enter the following command replacing username and computername with your physics account name and the name of your computer: ssh -L 59000:localhost:5900 username@computername.nat.physics.ox.ac.uk
You will then be prompted for your physics username and password twice, once for the ssh gateway and once for your desktop.
Once the tunnel is open keep open the Terminal window until you have finished your session.
Now follow the instructions to connect to the system from the instructions for your operating system however replace the name of your computer with localhost:59000 e.g. vnc://localhost:59000

In Finder click Go > Connect To Server from the menu bar at the top of the screen.
In the Server Address window type the name of the computer you wish to connect to e.g vnc://asosxXX.nat.physics.ox.ac.uk, vnc://alosxXX.nat.physics.ox.ac.uk
You will then be prompted to enter you physics username and password
If someone else is already logged into the system you will be prompted to either ask permission to share their screen or login with a new session.
When you have finished with your session log out of the system and close the Screen Sharing application.
