Ssh – How to tunnel SSH over SSH

sshssh-tunneling

I have successfully setup a tunnel over SSH on linux mint, and can browse the web.

However, when I try to ssh using the same port, I get:

Couldn't establish connection to proxy: Network is unreachable
ssh_exchange_identification: Connection closed by remote host

In my mate-network-properties I have selected manual proxy configuration, and socks host is 127.0.0.1

So why doesn't ssh use that proxy information, and can I make it use said proxy?

You don't need to tunnel ssh. You can ssh to the intermediary host then ssh to anywhere else you need.

You can even do it in a single command by forcing allocation of a pseudo-tty using the -t flag:

me@inside$ ssh -t intermediary ssh external
Last login: Fri Sep 21 14:13:25 2012 from intermediary
me@external$ logout
Connection to external closed.
Connection to intermediary closed.
me@inside$

The only down side is that you have multiple SSH sessions. But I can't really see why that would be a problem.
