This works (sorry, forgot to mention in the original post).  However,
the name resolution has broken within the last week or two for names
such as ip6-localhost in Debian.

I suspect gethostbyname/getipnodebyname/getaddrinfo may be to blame,
hence the need for a tool which uses them exclusively, rather than a
DNS resolving tool.  Ideally, I'd like a tool which could test them
all independently.

As an example of the brokenness, Gnus will no longer successfully
connect to my leafnode NNTP server listening on ::1
(NNTPSERVER=ip6-localhost).  Previously, it connected flawlessly.  I
have the same problem with slrn as well.


Regards,
Roger
