XDMCP and Kerio Personal Firewall

[Angus Veitch]

Hello All,

A while back I had some problems getting XDMCP working between Win XP 
and Ubuntu.  The Ubuntu login screen loaded successfully, but upon 
logging in all I got was a blank brown screen.  I've recently figured 
out that the problem all along was Kerio Personal Firewall, which was 
running at the Windows end.  Apparently other users also have found that 
Kerio is somehow incompatible with XDMCP, even when an appropriate 
filter rule has been defined.

I switched to another firewall (Jepico) and XDMCP now works beautifully 
with Cygwin/X.

I just thought I'd report this in case other Kerio users have 
experienced the same problem and haven't suspected the firewall as the 
cause.

Cheers.
