Ubuntu – NX/SSH remote access with Remmina

freenxopensshremote accessremote desktopssh

After many days and a lot of frustration, I managed to get freenx to work on my home server. I can connect to it with nomachine's linux client, but I want to use Remmina for this purpose. The problem is that I don't exactly know how to connect to a NX-server with the program.

In the connection dialog, I've chosen SSH as the protocol, and I've correctly added the IP and port. Under "SSH Authentication" I've added my user name on the server, and I choose "identity file" and selected the ssh-key I generated (which works with nxclient). (When am I supposed to provide my password for the user on the server?)

When I try to connect I get the message:

SSH public key authentication failed: Public key file doesn't exist

Why do I get this message? How shall I proceed correctly to get the authentication working?

Thank you for your time!

Remmina actually has a separate plugin for connecting to NX servers. You can get it by installing the remmina-plugin-nx package. Once you install that, you will have NX available in the Remmina connection dialog.

You may also want to try a separate program called qtnx. It's also available in the Software Center. It's a little simpler and seems to work better for me when connecting to NX servers.

Make sure port 3389 is opened on your firewall and router.

In Remmina edit your connection, click the "Advanced" tab and choose RDP under the "Security" option and save.

ssh -vv myuser@xx.xxx.xx.xxx
OpenSSH_5.9p1 Debian-5ubuntu1.1, OpenSSL 1.0.1 14 Mar 2012
debug1: Reading configuration data /home/viggy/.ssh/config
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 19: Applying options for *

Applying options for * means that the ssh client thinks that the host you are connecting to is not in the config file.

Based on your comments to the other answer you already moved every host specific setting to the top of the config file, before the "Host *" section, so parsing can't be a problem now.

But the ssh client still can't find that host in the config file which can only mean that the Host which you wrote into the config file differ from the one which you wrote on the command line when you invoked ssh. Are you sure that the Host you wrote in the config file is EXACTLY the same as what you write on the command line? (It has to be exactly the same, names are not converted to a canonicalized host name before matching.)
