Hi all openssh devs out there. I have quite a few Host-stanzas in my .ssh/config to keep track of all the different settings and credentials needed to access all different hosts I connect to. Now I have ran in to a problem where I need to switch settings based on what user I'm trying to login to a host as. A simple case is: ssh -i rootkey root at host123 vs. ssh -i userkey username at host123 Up until now I have just used a stanza like Host host123 User username IdentityFile userkey But it would be awesome of it was possible to add before that, eg fist match as all other blocks, a stanza looking like: Host root at host123 IdentityFile rootkey So when I type: "ssh host123" it resolves to equivalent of "ssh -i userkey username at host123" And when i type: "ssh root at host123" it would resolve to "ssh -i rootkey root at host123" Does this sound reasonable to the rest of you? //Anton Ps.

Hi,
Why not just do :
Host rhost123
User root
IdentityFile rootkey
Host uhost123
User user
IdentityFile userkey
Why not just do :

It's pretty easy if anyone wants to have a go at it - most of the infrastructure already exists for the "Host" directive. -d
