RE: "Cannot open display" or XDMCP problem ?

[Robert, Francois]

I tried Clive's suggestion to use a fixed IP address instead of my DHCP
attributed address, and also I tried the -from option. To no avail : 

XWin95 -screen 0 1024x768x16 -whitepixel 255 \
-blackpixel 0 -query 129.227.62.246 \
-from 129.227.62.61 &
xhost +  &

_XSERVTransmkdir: Owner of /tmp/.X11-unix should be set to root

Fatal server error:
XDMCP fatal error: Session declined No valid address

$ xhost:  unable to open display "129.227.62.61:0.0"

BTW, and in case this helps, I also have an NT4.0 deskstop machine (which
also gets its IP from DHCP...) with Cygwin 1.1.8 + XFree 4.0 (not 4.0.3)
where I can get the XDMCP working with this very Solaris server (although I
have another weird problem: no text is visible. Looks like it cannot
find/print fonts. But it does not complain about it). I would rather prefer
to get my Win95 laptop working if I can...
