Comment #5 on issue 28 by martin.r... at gmail.com: add syntactic sugar  
to "ssh:" scheme for bouncing through multiple hosts

Like suggested in comment #4, this functionality can be achieved with  
ProxyCommand option for openssh.

Let say you're able to connect to host outer.host.example.com with public  
key authentication and from there to inner.host.example.com also with  
public key authentication (key is loaded in ssh-agent and agent connection  
is forwarded).

Then by configuring following entry in $HOME/.ssh/config ...


host outer-inner
                 hostname inner.host.example.com
                 compression yes
                 protocol 2
                 ProxyCommand ssh outer.host.example.com "/bin/nc %h %p"
                 ForwardAgent yes

... will allow you to ssh to inner host in one step ...

   ssh outer-inner

... or use xpra from your client as ...

   xpra attach ssh:outer-inner:DISPLAY_NUMBER

It works perfectly for me.
