Logging in to your Account

The CCB cluster can be accessed on the command line or graphically using the Remote Desktop Protocol (RDP). A connection via RDP to the CCB servers will create a virtual desktop allowing you to run both graphical and command-line tools.

Please note that access to the CCB systems requires the use of the University VPN from outside the main Oxford network.

If you need simple terminal access then connections to the server can be made using SSH. SSH clients are built-in to Windows, Mac and Linux. To connect to the CCB, open your terminal application and enter the following command:

ssh -l your_user_name cbrglogin1.molbiol.ox.ac.uk

Please note that you will need to substitute your CCB user name in the command. Also, as described here, in general we see that cbrglogin1 is extremely busy and you may want to use one of the other login nodes.

Open the Start menu and type “Remote”, then click “Remote Desktop Connection”:

Press ”Show Options” on the bottom left:

Enter “cbrglogin1.molbiol.ox.ac.uk” and your CCB user name under “Username”.

If you prefer not to type your password every time, tick the box “Allow me to save credentials”:

Press “Connect”. When prompted, enter your password and press “OK” or “Enter”:

IMPROVING RDP PERFORMANCE

If you have problems with RDP performance, there’s a few things you can change to make it faster.

On your remote desktop:

 - Turn off display compositing:

  • Applications > Settings > Window Manager Tweaks > Compositor > (Untick "Enable display compositing”)

 - Use a plain desktop wallpaper:

  • Applications > Settings > Desktop > Background > Style: > None

 

SUSPENDING AND RESUMING YOUR SESSION

If you have a long-running job you need to monitor, or a rich environment with lots of open programs, it’s a pain to have to log out one day, log in the next and get everything set up just right. Thankfully, you don’t have to.

To suspend your session and leave everything as it is on the cluster for another time (up to a maximum of ten days), click the cross on the top right of the blue menu bar and then choose “OK” from the pop-up dialogue:

Install the 'Microsoft Remote Desktop' app from the Mac App store, at:

Logging in

IMPORTANT: To protect your research, access is restricted to University networks. Make sure that, if you are not working on the University network, you have connected to the University Virtual Private Network (VPN). If you try to connect from the internet it will not work.

 

Open the Microsoft Remote Desktop app and navigate to the “PCs” tab at the top:

Enter “cbrglogin1.molbiol.ox.ac.uk” next to “PC name”, then choose “Add User Account” from the “User account” drop-down box:

Add your CBRG username and password and click “Add”:
