cloos commented on ASTERISK-21065:
----------------------------------

Falling back to v4 when v6 cannot route will not help this case.

He has a route to ::1, it is just that nothing is listen(2)ing there.

Most dists these days have hosts(5) configures such that localhost only maps to 127.0.0.1 and ::1 maps to ipv6-localhost, for exactly this reason.  Too many complaints from their users that things started breaking as soon as they enabled ipv6 in their kernels.

That said, asterisk should get a list of addresses back from the getaddrinfo(3) call.  It would not be a bad idea to try each in turn until connect(2) succeeds or it runs out of addrinfo structs.

The reporter’s other solution would be to listen(2) to ::1 either in addition to 127.0.0.1 if his net.ipv6.bindv6only==1 or instead of 127.0.0.1 if net.ipv6.bindv6only==0.
