--=-=-= Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hi, Whenever I execute getaddrinfo() function from libc with a 'hostname.local' address as an argument and AF_INET6 as ai.ai_family, I get an IPv4 address, even when 'avahi-resolve-host-name -6 hostname.local' returns an IPv6 address. I've written a test program getaddrinfo.c[1] which does a getaddrinfo() function call and prints the result on the terminal. Following is the patch to port dns/nss_mdns which will fix this issue: =2D--->8---->8----- diff -urN /usr/ports/dns/nss_mdns/Makefile nss_mdns/Makefile =2D-- /usr/ports/dns/nss_mdns/Makefile 2008-01-03 17:53:37.000000000 +0530 +++ nss_mdns/Makefile 2008-04-27 01:22:10.000000000 +0530 @@ -7,7 +7,7 @@ =20 PORTNAME=3D nss_mdns PORTVERSION=3D 0.9 =2DPORTREVISION=3D 5 +PORTREVISION=3D 6 CATEGORIES=3D dns ipv6 MASTER_SITES=3D http://0pointer.de/lennart/projects/nss-mdns/ DISTNAME=3D nss-mdns-${PORTVERSION} diff -urN /usr/ports/dns/nss_mdns/files/patch-src__bsdnss.c nss_mdns/files/= patch-src__bsdnss.c =2D-- /usr/ports/dns/nss_mdns/files/patch-src__bsdnss.c 2007-04-12 16:13:15= .000000000 +0530 +++ nss_mdns/files/patch-src__bsdnss.c 2008-04-27 01:19:18.000000000 +0530 @@ -197,7 +197,7 @@ + * 2.
