[Remmina-common] Question: Remmina-NX under Ubuntu 12.04 Connecting to NoMachine OSX

[DiagonalArg <sou...@ni...>]

I am running ubuntu 12.04 fully updated, Remmina (0.9.99.1) with the NX plugin.  I am trying to connect to a server for which I have SSH access via ssh key (in ~/.ssh/id_rsa) but _not_ via password.  I am connecting to an OSX Mavericks server running NoMachine.  I have been able to connect Ubuntu/NoMachine to OSX/NoMachine on the local network.  Now I am trying Ubuntu/Remmina to OSX/NoMachine remotely.

I am quite confused on the settings & the responses I'm getting.  Under the Basic tab, I put the server IP and pointed it to my ssh key.  For username/password, I gave the username/password of my account on the OSX server (though I am not able to use that password for ssh, you understand, only the key).  When I try to connect, I get: 


"NX SSH authentication failed: Access denied. Authentication that can continue: publickey"


When I try going under the SSH tab and enabling the tunnel for "same server at port 22" and using "Public Key (automatic)" or pointing at my identity file (my ssh key), it gives me the same response whether I use "tunnel via loopback address" or not.


 Finally, I tried setting up a tunnel connecting my local port 4000 to port 4000 on the mac, and then using remmina to connect to localhost:4000 with the uname/pwd of the OSX server (I also tried uname/pwd of my local machine, which runs sshd and is accessible via password).  In either case, I received:


"Failed to startup SSH session: timeout connecting to localhost"


I am very confused.  Can someone help?
