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.
