[FreeNX-kNX] FreeNX problem with latest version on Gentoo.

Mon Dec 19 19:36:16 UTC 2005

Hello,

I have a problem using FreeNX. I have a Gentoo machin on my networks
border, and first installed FreeNX using the ebuilds coming with
Gentoo. This installs FreeNX 2.8 with NX 1.4

This did work on occasion, but I had some issues, and decided to
upgrade to the latest verions before asking for support here. But I
know have a problem. Basically it doesn't work anymore.

The setup:

I have a Desktop, running Suse Linux. This desktop is part of my home
network, and is connected over the internet via a Gentoo Linux based
firewall. On this firewall I installed FreeNX. I als have a Windows XP
laptop. My goals is to be able to use the Nomachine NX client, connect
with that to the NX service on the firewall, and have NX connect to
the VNCserver on my desktop. With FreeNX2.8 /NX 1.4 I got this more or
less working. Even on  a slow connection.

Now with FreeNX 4.2 /NX 1.5 it isn't working anymore. The connection
with the NX service on my firewall works, as I do get a lot in the
log. I upped the logging level to 7, and this is what I typically get:

-- NX SERVER START: -c /usr/NX/bin/nxserver

In the above log there is one thing that strikes me as odd: The
version NXserver seems to think it is running is 1.4, but I am
possitive I am on 1.5. Running nxproxy - v confirms this.

The NX client's log is this:

Warning: Overriding auxiliary X port with port '7001'.
