From outside ECMWF, you may use use Teleport through our gateway in Bologna, jump.ecmwf.int. Direct access through ECACCESS service is not available.

# or for users with no formal access to HPC service:
$> ssh ecs-login


Tip
titleSSH key-based authentication within ECMWF

The first time you log in, we strongly recommend you set up your local SSH key-based authentication with the following command:

No Format
$> ssh-key-setup

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

Warning
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.

Info

Upon logging in, please take a look at the message of the day displayed on the login nodes (or review /etc/motd). 

You can also open a JupyterLab session through the ECMWF JupyterHub service. See HPC2020: Jupyter Sessions with JupyterHub for more details.

Tip
titlePassword access

If you have not changed your password since 18 January 2021, password access may not work.

...

You can use the hpc-* or hpc2020-* names in the table below if you just need to use the default HPCF complex, or the specific names for each of the complexes. For ECS, you may use the ecs-* names. Your usual interface to connect would be the *-login names, and for remote submission of jobs we would recommend using the *-batch names as they are dedicated login nodes for job submissions. If you need to set up a cronjob, then the *-cron names are to be used.

Once there, check if you already have an existing ssh key pair:

Password-less access between Atos HPCF nodes and other platforms

Info

This step is required for many tools and applications to work well, such as ecinteractive, ecflow, and ecaccess jobs.

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.

If you don't, you may generate them like so:
