bad packet: I can ssh into server, but not on newly installed nxclient
 

Although I successfully use NoMachine nxclient on a Mac to work on a remote linux machine, I am unable to use NoMachine installed on Ubuntu 12.04 to access the same remote linux machine.

The error details mention a "bad packet", and I am not sure how to fix this. I have some idea of what typically causes such errors (bad encryption, incompatible ssh protocols), but I do not know where to begin to fix it.

I think both my ssh client and the host supports protocol 2.

Ideas?

lets try.

1. Did you tried to login using SSH from Ubuntu Machine to the 'Same remote Linux Machine'?. If yes was it successful.? Also use the same username & password for nx client as SSH login

Nor can I vnc view a Mac.
 

Answering this question:

Yes, ssh from Ubuntu to (I think it's CentOS) works fine, using the same username & password for nxclient.

On a related note, I also cannot remotely view the desktop of my mac pro. Using my macbook pro, I CAN view the desktop of my my mac pro, but following the same line of steps does not work in Ubuntu for me.

Thanks for try # 1.

What about Log messages for nx server on destination machine?

If I get it right, there is only a nxclient, but no server for OS X. Are you using the builtin screen-sharing in OS X to get the desktop of the Mac Pro on your MacBook?

yes
 

yes, an nxclient, on Ubuntu that fails to connect to a nxserver. There is also a vnc viewer on the same Ubuntu machine that fails to connect to OS X (via screen sharing)

They should at least be able to connect between two Linux machines.Yep, we found the same. The screen sharing used in OS X is not the default VNC.

I don’t know about the features of nxserver/client. Maybe TeamViewer is an option for you?
