Re: Using a 'bastion' - issue when providing password

[Kai Großjohann]

I'm hoping that it can be made to work somehow, just need to figure out 
how.  Get "ssh rt" working outside Emacs, then perhaps it works inside 
Emacs, too.

You could try "ssh -vvv rt" for a start, that should show you a number 
of debug messages.

You could try to change the ProxyCommand to add "-vvv" to the ssh 
command in there.

You could compare whatever you get from "ssh rt" with what you get when 
you type the proxy command manually (use the same "-vvv" in both cases).

Am I making sense?  Does this explain the approach I'm thinking about?
