[SOLVED] Setting up a SSH gateway.

nolretou · 04-22-2014, 04:58 AM

Hi !

I would like to create a SSH gateway server in a special way.
I use Slackware, and would like to use key auths.

The SSH client is A.
The gateway is B.
The SSH server i'd like to connect to is C.

C creates a connection to B, A connects to B, so A automatically connects to C through B.

B<--C
A-->B
A-->B-->C

I'm a bit lost in sshd options, and have some difficulties finding tutorials on Google.

First tests.

I had to add "GatewayPorts yes" to the gateway server's sshd_config, otherwise it was listening to 127.0.0.1 only.

Now when i try to connect from the client, i have a "ssh_exchange_identification: Connection closed by remote host".

I forgot to start the SSH server on the C machine !
It's working now.

I'll do more tests and come back if needed.

Meanwhile thanks for the help.
