[FreeNX-kNX] Mac client trouble on Leopard?

Thu Feb 7 16:48:06 UTC 2008

Hey everyone,
First, I have no clue if:
* this output is of any use
* this is the right mailing list! Seems to be the only NX related one  
I could find.

Anyway. I just found out about NX yesterday, and set it up on my Linux  
server box. It works fine to connect from windows, but not from OS X.
It seems to connect, log in etc, but perhaps 10-15 seconds after  
launching X11.app the window closes, just after "established the  
display connection". 5 seconds later, a new window pops up with "The  
connection with the remote server was shut down. Please check the  
state of your network connection."
Well, the network connection is fine, since it works to connect from  
the same computer in Win XP (under VMware Fusion).

The full logs are a bit too much to post, but here's the seemingly  
important part of sshlog:

[...log in here, looks fine...]

... etc.

The client version is 3.1.0-6 (both windows and OS X) and server 3.1.0  
(gentoo 3.1.0-r1 ebuild).
BTW, I can't connect to the testdrive servers from OS X either, but  
they too work in windows, so this has to be a client-side issue.
The client computer is a Macbook Pro (Core 2 Duo), running Leopard  
10.5.1.

Thanks in advance.
