SSH connection failure

On Debian establishing SSH connection from Winswitch fails with the following error:

Hmm, I've never seen this.

It looks like the ssh version string is interpreted as a command sent by the remote endpoint. I will have to test this against the same version of debian/ssh to figure out what is happening here.

Are you using keys or ssh password? Anything else I need to know to reproduce? (client's ssh version?)

[onlyjob]

Thanks, this is only happening with password authentication.

ssh client version is 'OpenSSH_6.0p1 Debian-2, OpenSSL 1.0.1c 10 May 2012'
(package 'openssh-client' 1:6.0p1-2)

Which version of debian do I need for testing? wheezy on both client and server?

[onlyjob]

Yes please.

Just tested and it worked just fine, I used a single VM and connected via ssh to 127.0.0.1.

I think maybe you've set port 22 but you have also unticked "ssh tunnel" - see screenshot. Feel free to re-open if not.

example of a connection settings pane with ssh tunnelling enabled

Quite possible that I did exactly that - many thanks for your explanation. I'll try again with remote machine and report.
