Sorry, Ron - I accidentally replied to you instead of the list. Anyway,
for everyone else. this is the answer:
Thanks, yes; I'd just found this myself, at
http://etutorials.org/Networking/network+security+hacks/Chapter+1.+Unix+Host+Security/Hack+9+Prevent+Services+from+Bindi+ng+to+an+Interface/
Ron is indeed right, but oddly enough I do have the same line in
/etc/X11/xserverrc but the 'nolisten' switch is being ignored on this
machine. If I start X with 'startx -- -nolisten tcp' everything works.
Probably needs a bug report.
