Does anyone have experience fixing NoMachine NX and FreeNX? I am using Ubuntu 11.04, I've successfully installed the NoMachine Client, Node, and Server. I have also successfully generated my own SSH keys and made the necessary changes to my ssh and sshd configuration files. Lastly, I am not behind any firewall or anything like that.
When I attempt to connect to my machine (via my static IP address), the RSA authentication goes through just fine (this is visible if I do an ssh -vv ...) but then the connection just freezes for about 60 seconds and then I get an error that says the connection to my IP address closed, and a NoMachine window pops up that says:
NX> 203 NXSSH running with pid: 15723 NX> 285 Enabling check on switch command NX> 285 Enabling skip of SSH config files NX> 285 Setting the preferred NX options NX> 200 Connected to address: ***.***.**.*** on port: 22 NX> 202 Authenticating user: nx NX> 208 Using auth method: publickey NX> 900 -c, /usr/lib/nx/nxserver, , ... NX> 900 Won't execute arbitrary commands. NX> 280 Exiting on signal: 15
I cannot find any help with an error like this. I've already tried re-installing NoMachine and FreeNX and using a new RSA key, and it always gives the same result. Like I said above, the output of ssh -vv shows that the RSA authentication is successful and then after that, the connection always freezes.
