Tip
titlePasswordless access with Teleport

If you wish to have password-less access, you will need to add the following entry to your ~/.ssh/authorized_keys on the Atos HPCF:

No Format
curl -fs https://nexus.ecmwf.int/repository/internal-teleport-configs/prod/teleport_user_ca.pub >> ~/.ssh/authorized_keys

Alternatively, if you have an ssh key pair on your end user device, you could also add your public key into ~/.ssh/authorized_keys on the Atos HPCF for the same effect.

Direct access from outside ECMWF through ECACCESS is not available. You must choose a valid host such as ecgate, and once there ssh into the desired host.
