Configuring password-less login

Info

This configuration enables single-hop ssh (using ProxyJump) to LXC or any other host.

Not required for ECGATE, CCA/CCB login nodes, Linux physical workstations , and Linux VDI, or HPC2020 TEMS.

Add the Teleport certificate authority to your ~/.ssh/authorized_keys file, on the relevant system at ECMWF, e.g. ecgate, cca:

Code Block
languagebash
curl -fs https://nexus.ecmwf.int/repository/internal-teleport-configs/prod/teleport_user_ca.pub >> ~/.ssh/authorized_keys


Note

On cca/ccb, you will need to load the curl module beforehand.


Tip

This configuration will allow access to any host which mounts the same $HOME directory.
