From outside ECMWF, you may use use Teleport through our gateway in Bologna, jump.ecmwf.int. Direct access through ECACCESS service is not available.
...
You may also connect via SSH from another ECMWF platform . If you do so from ECGATE or the Cray HPCF you will not need a password to log insuch as the Linux VDI.

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

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 | ||
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 . |

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:

$> ls ~/.ssh/id_*
~/.ssh/id_rsa ~/.ssh/id_rsa.pub |
If you don't, you may generate them like so:

$> ssh-keygen # press 'enter' 3 more times |
Make sure it is added into the different platforms to be used

$> ssh-copy-id -i ~/.ssh/id_rsa.pub ecgate # also gives access to lxc and linux workstation
$> ssh-copy-id -i ~/.ssh/id_rsa.pub cca
$> ssh-copy-id -i ~/.ssh/id_rsa.pub hpc-login
# or for users with no formal access to HPC service:
$> ssh-copy-id -i ~/.ssh/id_rsa.pub ecs-login |
Copy your key pair onto those platforms so you can make the connections in both directions:
