Describe when someone would need this information. For example "when connecting to wi-fi for the first time".

Step-by-step guide

Pre-requisite: please create a ssh config file .ssh/config  adapting the template below. 

Host ela
    HostName ela.cscs.ch
    User <username>
    IdentityFile ~/.ssh/cscs-key

Host daint-ela
    Hostname daint.cscs.ch
    User <username>
    IdentityFile ~/.ssh/cscs-key
    ProxyJump ela

Host eiger-ela
    Hostname eiger.cscs.ch
    User <username>
    IdentityFile ~/.ssh/cscs-key
    ProxyJump ela

Note:

1. The ssh config file can be written in many different ways, the template above is for your reference only
2. The <username>  in the above snippet needs to be configured with your cscs username
3. The naming convention for Host  is given as daint-ela or eiger-ela as an example: please adjust it to your own preference

Step - 1: Please log in to the SSHService web application to generate keys and download (or) or download the keys using the sshservice-cli 

Step - 2: Make sure the downloaded keys are copied to the folder ~/.ssh with names cscs-key  and cscs-key-cert.pub. The permission of cscs-key should be set as 600 

The above two steps are required if you are connecting for the first time or if the downloaded keys got expired.

Step - 3: Connect to Piz Daint or Eiger via the frontend Ela using the commands below:

ssh daint-ela 

OR

ssh eiger-ela
