Famous last words.
ssh binds its tunnel port explicitly to 127.0.0.1. vncviewer, when
given an empty host name, uses an ipaddress of 0.0.0.0 which doesn't
match this. Running vncviewer as
$ vncviewer localhost:1
instead of
$ vncviewer :1
works fine.
This could be considered a bug in vncviewer, although I'm not really
sure of that.
The only (very minor) remining issue is that the ip(4) man page seems
to be incorrect: _proto_ of zero does not give a raw socket. I
downloaded vncviewer source, and then changed the socket calls to
explicitly use IPPROTO_TCP, and the behaviour was the same.
Sorry for the confusion.
Dale.
