 +=== multiple ssh key ===
 +It is possible to register multiple SSH public keys on the authentication server. However, [[https://my-account.unige.ch/|my-account.unige.ch]] does not allow this at the moment (work in progress). In the meantime, please send your request to the LDAP team directly at dl-distic-windows-team@unige.ch.

 +===== Alternative to using ProxyJump =====
 +
 +ProxyJump doesn't work with host based authentication, this is the reason why you need to use a ssh key in the previous setup. The reason is because ProxyJump doesn't open a real ssh session and thus the ssh-keysign isn't run when you connect. Instead of using ProxyJump, you can proceed as follow:
 +
 +<code>
 +Host baobab
 +    HostName login1.baobab.hpc.unige.ch
 +    User <youruser>
 +    
 +Host cpu*
 +    HostName %h
 +    User <youruser>
 +    ProxyCommand ssh -tt baobab ssh %r@%h
 +</code>
 +
 +Usage: ssh cpu001
