You can connect for the first time via SSH from another ECMWF platform.

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

|---|---|---|---|---|
| If connecting from ECGATE or CCA/CCB no password will be asked. From other platforms you will have to use your ECMWF password to connect.||||
If you have not changed your password since 18 January 2021, password access may not work. |

Check if you have an existing rsa key pair on other ECMWF platforms:
No Format $> ls ~/.ssh/id_rsa* ~/.ssh/id_rsa ~/.ssh/id_rsa.pub
If you don't, you may generate them like so:
No Format $> ssh-keygen -t rsa # press 'enter' 3 more times
Make sure it is added into the different platforms to be used
Note If the key was already present in the
~/.ssh/authorized_keysfile, it will be duplicated.No Format $> ssh-copy-id -i ~/.ssh/id_rsa.pub ecgate $> ssh-copy-id -i ~/.ssh/id_rsa.pub cca $> ssh-copy-id -i ~/.ssh/id_rsa.pub aa # or if you don't have access to HPCF: $> ssh-copy-id -i ~/.ssh/id_rsa.pub aa
Copy also your private key onto those platforms so you can make the connections in both directions:
No Format $> rsync -av ~/.ssh/id_rsa cca:.ssh/ $> rsync -av ~/.ssh/id_rsa aa:.ssh/ # or if you don't have access to HPCF: $> rsync -av ~/.ssh/id_rsa ecs:.ssh/
