External access
If you are using Teleport, Direct access from outside ECMWF through ECACCESS or Teleport is not available yet. However, if using the latter a chained ProxyJump could be configured as an interim measure. Below is a suggested entry which you need to place in your End User Device's ~/.ssh/config
. It also includes the settings for X11 forwarding and to avoid your connections to drop after a period of inactivity. Note you must set your ECMWF username in the User
option

Direct access from outside ECMWF through ECACCESS is not available. You must choose a valid host such as ecgate, and once there ssh into the desired host.
Password-less access from / to other platforms
...
Check if you have an existing rsa ssh 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_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 # or for users with no formal access to HPC service: $> ssh-copy-id -i ~/.ssh/id_rsa.pub ecs
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 for users with no formal access to HPC service: $> rsync -av ~/.ssh/id_rsa ecs:.ssh/
