Christian, would you have time to help us out here? We could really use a
Windows test build made from S2_2 with this patch applied.

Just played with the v7 patch on S2_2 on my system (Ubuntu Linux 9.04). Looks
good.
Tried all my tests from comment #22 and comment #23 and they all work without
any errors.
Tried making something listen on IPv4 only (nc -l -p 5556 appears
Follow-up Comment #31, bug #15559 (project freeciv):
try to listen on all available IP address families (specifying
V6ONLY for lack of ambiguity), and fail if it can't bind all
of them.
Just take care of not failing when it's impossible to bind IPv6 address on a
system where IPv6 has been
Follow-up Comment #30, bug #15559 (project freeciv):
From x11_create_display_inet() of openssh-5.6p1/channels.c:
for (ai = aitop; ai; ai = ai-ai_next) {
if (ai-ai_family != AF_INET ai-ai_family !=
AF_INET6)
continue;
Follow-up Comment #27, bug #15559 (project freeciv):
If freeciv-server says IPv4 bind failed: Address already in use,
then its IPv6 socket might accept IPv4 connections.
That error message would seem quite alarming for someone who does not know
that it's actually ok in his/her setup. Any idea
Follow-up Comment #28, bug #15559 (project freeciv):
IPv4 bind failed: Address already in use
Print that particular error message only if also IPv6 bind failed?
To be exact, print no error messages if we can listen() to at least one
socket?
OpenBSD 'man getaddrinfo' shows an example of this:
Follow-up Comment #29, bug #15559 (project freeciv):
Clearly the server should run without emitting error messages regardless of
whether it finds itself on a v6only behaving system. Specifying
setsockopt(V6ONLY), or whatever it's called, with the current code might be
sufficient, if it's

Just found time to play a bit more.
I did sysctl -w net.ipv6.bindv6only=1 to try to reproduce the problem.
Without the patch, starting a server from the client works, but starting a
server manually and then trying to connect to it with IPv4
Follow-up Comment #24, bug #15559 (project freeciv):
I did look in the some older version of the patch, and I'm certain it works
on linux. My only concern is that it has not been much tested with other
systems (I can *try* to find time to make Windows/MinGW build). It needs more
exposure before
Follow-up Comment #25, bug #15559 (project freeciv):
I'd prefer to retarget for 2.2.4. AFAIK it's been like this in all 2.2.x
releases so I wouldn't consider it a showstopper.

Follow-up Comment #18, bug #15559 (project freeciv):
I changed the error code in server/sernet.c to try to identify the socket
that causes the error. I also remade the trunk patch, so now trunk seems to
work.
This is the *last* version of the patch from me, unless I discover that I
made some
Follow-up Comment #17, bug #15559 (project freeciv):
I made a trunk version of the patch, but it is broken. The client complains
about unknown error 0 and the server says '2: Lost connection: c1 from
localhost (connection incomplete).' I might have made a mistake in
client/clinet.c; I need more
Follow-up Comment #16, bug #15559 (project freeciv):
gcc gives the same warning to me. gcc notices that if name_count = 0, then
we never enter the for loop to initialize 'sock'.
I am attaching a -v4 patch that prevents the warning. The patch is for S2_2.
I have never used trunk. I am now

This seems like gcc stupidity, but needs to be fixed anyway.

My -v2 patch (from S2_2 r17797) causes a merge conflict in server/sernet.c. I

AF_INET6 configure check is now bug #16458.
Failure to close extra connections is now bug #16461. (I was wrong. This is
not a new bug, because one socket is already enough to accept too many

While I am using my patch (file #9838),
'./ser --bind ::' starts an IPv6-only server,
'./ser --bind 0.0.0.0' starts an IPv4-only server.
If I run IPv4-only server, then my Freeciv client can connect to '127.0.0.1'
but refuses to connect to
Follow-up Comment #7, bug #15559 (project freeciv):
I have a similar bug using OpenBSD. I am running an old snapshot of OpenBSD
4.5-current.
My server (S2_2 r17748) accepted connections from localhost and from
127.0.0.1, but not from ::1. I found that my server had no IPv6 support,
because
