TCP Proxying SSH connections

[far-blue]

Has anyone worked out how to get SSH connections to work via the TCP Proxy facility?

I get ssh_exchange_identification: Connection closed by remote host

There's no real debug info available. My suspicion is that the handshake is failing because the IP address of the client doesn't match the IP address of the proxied connection - or the same in revers for the server.

I don't think the problem is one Fabio can fix but I wondered if anyone else had worked out how to configure the ssh server and client so they don't get upset.

Interesting. Please share a solution if you find one. — Frank Schröder

I worked it out and it wasn't an ssh issue after all :) I use Nomad and Bitbucket Server and had created 1 service with 2 tags - one for http and one for the tcp proxying. Nomad had created the service in a way that resulted in both the http proxy and the tcp proxy routing to the container's http port 8080.

The solution was to split the config into 2 services, each with a specific port number in the nomad config.
