These are the SSH public key fingerprints for the Maths SSH gateway, gate.maths.ox.ac.uk:

ED25519: SHA256:hpOt1YqdVGQgZtI8eSY888WskCkyEZOQhSjtWXq05ik
ECDSA: SHA256:mOWA5dDywlRqF/bLQZx+TnKyOB5GI/SBxNO6rd2T2nc
RSA: SHA256:rWHKL342CfIeZoAcMHL3x2rLnk2V3iq+7F0iVZlfYpQ

You can add the following entries to your ~/.ssh/known_hosts file:

Other machines

Once you are connected to gate, you can SSH to other departmental machines and their public keys will be verified automatically.

If you use gate as a jump host (e.g. ssh -J USER@gate.maths.ox.ac.uk USER@target-machine.maths.ox.ac.uk) and you want to check the fingerprint of the target machine, you can run this command on gate:

grep ^target-machine, /etc/ssh/ssh_known_hosts | ssh-keygen -lf -

Note that only one key type may be listed (ECDSA at time of writing).

To get the full public key to add to your ~/.ssh/known_hosts file:

grep ^target-machine, /etc/ssh/ssh_known_hosts

SSH keys for machines other than gate are replaced whenever the machine is reinstalled or upgraded.
