-
Generate a pair of ssh keys. It is useful to have a pair of keys per destination:
ssh-keygen -f $HOME/.ssh/fawcett
Secure the key with a strong passphrase when prompted.
-
Copy public key to a Maths computer:
scp $HOME/.ssh/fawcett.pub CRSID@ssh.maths.cam.ac.uk:
-
Now ssh to your account in Maths and there run command:
ssh-copy-id -f -i $HOME/fawcett.pub fawcett
Now you can remove fawcett.pub from ssh.maths.cam.ac.uk
-
Now you should be able to access fawcett with command:
ssh -i $HOME/.ssh/fawcett -J CRSID@ssh.maths.cam.ac.uk CRSID@fawcett.maths.cam.ac.uk
-
You can automate the options above by adding the following lines to file
$HOME/.ssh/config on your computer: Host fawcett.maths.cam.ac.uk User CRSID ProxyJump CRSID@ssh.maths.cam.ac.uk IdentityFile ~/.ssh/fawcett
Afterwards you should be able to connect to fawcett with command:
ssh fawcett.maths.cam.ac.uk
- If that fails then please send the output of
ssh -v fawcett.maths.cam.ac.uk
to the IT helpdesk.
