Can't use FreeNX from outside LAN

alpha1906 · 05-18-2006, 03:14 PM

I have installed the FreeNX and NX packages on my Slackware 10.0 box from http://www.slackware.com/~alien/slackbuilds/freenx/

I can access the box using FreeNX fine from a machine within my LAN. But if I connect remotely from outside my LAN, the NX Client times out. I have a router using port forwarding. For example port 12345 is forwarded to port 22 on my Slack box. I can log in via SSH fine also.

Anybody have any suggestions? Thanks.

Hi

Did you try to copy /etc/nxserver/client.id_dsa.key to somewhere outside your LAN and then try to do a remote ssh login like this:

Code:

ssh -p 12345 nx@your.server -i client.id_dsa.key

? You should be asked no password and be presented with this text:

Quote:

HELLO NXSERVER - Version 1.4.0-44 OS (GPL)
NX> 105

If not, something is wrong at the ssh / account level. If yes, did you enable debugging by setting

Code:

SESSION_LOG_CLEAN=0
NX_LOG_LEVEL=6

and then look at the session information that is left behind? Look in your ~/.nx/C-<hostname>-<display>-<session_id>
directory.

I was able to login via ssh with the client.id_dsa.key and got the 105 response. I looked at the nx session file and the following error was included"

What is being logged when you connect to your server with a NX server instead?

Sorry for the later response. I only get a chance to test this remotely on the weekends.

Back to the problem, do you mean the message returned from NX Client? This is after it stuck on "Negotiating link parameters" and it times out. I click the "details" button and get this:
