using laptop as second monitor?

thanks, this is exactly what I was looking for. But I have some 
usage-issues...

I compiled it on my pc as described on the homepage (download, copy host.def, 
make).
But I have some problems to start xdmx:
My PC has the IP 10.33.33.2 and the monitor's location is right from the 
laptop with the IP 10.33.33.1.
X (KDE) is running on both machines, I'm logged in on both machines.

I'm using the following command on my PC:
./Xdmx :1 +xinerama -display 10.33.33.1:0 -display 10.33.33.2:0
(or ./Xdmx :1 +xinerama -display 10.33.33.1:0 -display :0, this works the same 
way)

I get the following output:
-----------------------------
_XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6

-----------------------------
Some IPv6 warnings that can be ignored, I guess. (I don't use IPv6).
Then dmx successfully uses my PC's X but it cannot connect to the laptop.
Do I need to change the default X configuration on the laptop? The 
dmx-documentation doesn't seem to claim that; I cannot find information on 
the dmx-page for client-configuration.
Do I have to configure the laptop to accept network access or Do I have to 
configure it like a X-terminal that connects to my PC?
(I don't like the second idea)
btw: I disabled all firewall-rules on the laptop, so it must be some X-stuff 
that's wrong.


Thanks in advance,

Mark
