X and Fluxbox :: Displaying remote X-apps on DSL X-server

I am new to X, so maybe it is a dumb queustion...

I want to use my DSL machine (486 with 32 MB RAM and no hard disk) as a X-server.

I have another PC (in my network) running Windows XP, on which I installed CygWin with X support. I thought it would be possible to run an application on the Cygwin X client and display it at the DSL X-server.

DSL machine: booted and showing X screen
Windows XP machine: I typed in Cygwin X: "xclock -display 192.168.1.101"

where 192.168.1.101 is the IP-address of the DSL machine.

Unfortunately xclock didn't appear on my DSL machine, and Cygwin gave the message "cannot open display".

Is Cygwin X (Xfree) compatible with DSL X, or what am I doing wrong?

The DSL X server is loaded with "-nolisten tcp" which means that it won't listen for incoming connections over TCP. Try disabling that option.

Here is what I do:

XP/cygwin box:
export DISPLAY=192.168.1.101:0.0
which I guess is equivalent to what you do.

On DSL box:
xhost ip.adress.xp.box
which allows incoming X commands to the X server. I don't know if DSL comes with a firewall, but if it does, you may have to allow access to port 6000 which X uses.
