using xfree86 4.4.0 from remote host

[Oleg Leschov <kalmas at udm dot ru>]

What is the difference between XFree86 4.4.0 binaries for cygwin and the 
cygwin X packages? Is there any info on why XFree86 is removed from 
cygwin? Do the cygwin packages support font server usage? I want to use 
font packages and font server running on the linux box which lacks the 
video card.
I am currently trying to use XFree86/cygwin 4.4.0. Maybe I would have 
been more successful with cygwin stuff?
The problem is that I can't use the X server from the remote host. I 
have tried "xhost +<remoteIP>" and "xhost +" on the windows machine 
running xfree86. Both succeeded, but the remote says the same thing as 
before -
Xlib: connection to "10.0.5.1:0.0" refused by server
Xlib: No protocol specified

Error: Can't open display: 10.0.5.1:0.0
zsh: exit 1     xsysinfo
Log file does not says anything useful.
I am running X by just starting XWin.exe, having /etc/X11/XF86Config 
with following contents:
Section "Files"

   FontPath "tcp/10.0.5.5:7100"

EndSection


Section "Device"

  Identifier "a"
  Driver "cygwin"

EndSection

Section "Screen"

   Identifier "0"
   Device "a"

EndSection

What am I doing wrong?
