Connect through SSH gateway (jump host)

[Petri Karppinen]

Hi, is the iTerm2 supporting in the multi-hop? Example I first like to contact server1 which asking to passwords and when I login, I have to jump another server2.

I like this idea. I would use this feature often. My current solution is to open two tabs. one for the initial ssh connection to the jumpbox, one for the ssh session through the jumpbox. This can also be accomplished with the following command.. 

ssh -A -t user@jumpbox ssh -A -t  user@2ndhost

What makes this better than using the ProxyCommand in the user's ssh config file?  For example,

Host DEST

ProxyCommand ssh HOST -W %h:%p

where HOST is the intermediate system you have to bounce through.  Both port and user can be defined for the host.  One can also reference a host that also uses ProxyCommand, allowing many hops to be defined to ultimately get to the final system.  With the use of ssh keys, one doesn't even get asked for a password.

There isn’t built-in ssh support in iTerm2, so it's really a question for openssh.
