Examples of ProxyCommand?


As a test to find some examples of using ProxyCommand, I tried

ProxyCommand nc %h %p

that seemed to make no change I could see..

I have 3 computers with ssh servers on them and i'm trying to do some example
ProxyCommand lines so I can see what they do.

The only one i've got to work is ProxyCommand nc %h %p and I can't see
it doing anything.

And others i've tried aren't working.

One site said

ProxyCommand ssh user@intermediatehost nc %h %p

and to ssh to internalhost and it'd go through that.

But when I tried it just hung.

I did Ctrl-C and it said

ssh_exchange_identification: Connection closed by remote host
