Hi,

I'd like to use parallel-ssh to establish SSH tunnels (port forwarding) to (many) hosts. Right now, you can establish each tunnel manually using the Tunnel class in pssh.clients.native.tunnel. However, it would be cool to have a feature like the following:

hosts=[...]
client = ParallelSSHClient(hosts, other_args)
ports = client.open_tunnel(remote_host, remote_port, bind_ip)
# now, all traffic (from bind_ip) to localhost:ports[i] is sent to hosts[i], which forwards it to remote_host:remote_port

What I'm trying to do is the following:
I have a couple of hosts, each running an SSHD and the same set of services. The services only listen for connections from localhost (by intention). The current way of connecting to them is to establish a port forwarding through the SSHD to the respective service ports with ssh -N -L localhost:local_port:localhost:service_port user@host. I'd like to be able to establish one tunnel for each host with a simple API.

Best regards,
OOTS
