After a recent update of hpc-login ecs-login and other aliases, their host key has changed. You may get the following error when connecting:
It is safe to accept the new key. We are working on a permanent solution to avoid this problem in the future, but you will need to remove the corresponding entry for hpc-login or ecs-login on your ~/ssh/known_hosts file and add the new one by connecting again. |
You can connect for the first time via time via SSH from another ECMWF platform. If you do so from ECGATE or the Cray HPCF you will not need a password to log in.
...
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.
