Check if you have an existing ssh key pair on other ECMWF platforms:
No Format $> ls ~/.ssh/id_* ~/.ssh/id_rsa ~/.ssh/id_rsa.pub
If you don't, you may generate them like so:
No Format $> ssh-keygen # 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_keys
file, 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-login # or for users with no formal access to HPC service: $> ssh-copy-id -i ~/.ssh/id_rsa.pub ecs-login
Copy also your private key pair 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-login:.ssh/ # or for users with no formal access to HPC service: $> rsync -av ~/.ssh/id_rsa* ecs-login:.ssh/
