Doh! I was so blind! Windows XP does not have an IPv6 protocol installed
by default. I added it and the problem went away.
This sounds like a bug. XWin should verify whether a device which
supports the target protocol exists before attempting to open a socket
on it.
Yes, it shouldn't fail like this if IPv6 isn't installed
I suspect the same problem will occur if you use X -displayfd built with
IPv6 on linux kernel without IPv6 support
What is this used for? Sharing a local X session with someone else?
Logging onto an existing X session at work from home? I've only ever
used X locally or through ssh forwarding.
It's used to allow remote X clients to connect to an X server without
using a ssh tunnel (e.g. [1])
