The first time you log in, we strongly recommend you set up your local SSH key-based authentication with the following command:
This step is required for many tools and applications to work well, such as ecinteractive, ecflow, and ecaccess jobs, as well as convenient access from our VDI service | ||

We have recently updated the host keys for all our Atos HPCF nodes. If you get an error along those lines, See 2022-08-10 SSH host keys fixed on all nodes and Cron service for more information . |
See also HPC2020: Persistent interactive job with ecinteractive if if you wish to customise the resource limits of your interactive session.

Password-less access from / to other platforms
If connecting from a different platform at ECMWF and to enable password-less connections and transfers between different platforms, you will need to enable ssh key authentication.
Check if you have an existing ssh key pair on other ECMWF platforms:
