SSH tunneling suggestions/technique

veelck · 01-18-2012, 08:23 AM

I know this thread is crazy old, but did you maybe figure out how to do it?
I was trying searching forum and google, but couldn't find answer for exactly the same problem.

so:

1. localhost -> 2. middle server (do tunnel here) -> 3. server (inside local net, accessible only from 2.nd server through ssh)

What I'd like to achieve is set it up, that I can connect with ssh directly from 1. to 3., so I can move some files with e.g. mc without copying them first to 2. serv and then to 3rd.

Best,
Damian

Hi,

I can do that using ssh without any problems. Read the ssh man pages.

in '~/.ssh/config' I have the following lines

Code:

Host server3
        HostName server3
        IdentityFile ~/.ssh/rsa_key
        ProxyCommand ssh -W %h:%p server2

So if you are on server1 and want to connect through server2 to put a file on server3, the above should do the job.

Code:

server1$ scp testfile server3:

I hope this helps.

This works like a charm.
I did not setup the RSA for server2 (yet), so now when connecting I get two passwords to type, but it's exactly what I needed.

Thanks for quick response.

Best regards,
Damian
