Package: libc6 Version: 2.13-35 Severity: normal Tags: ipv6 Hi,
I recently configured IPv6 connectivity on my system using 6to4 on my router. It works, except that getaddrinfo() sorts IPv4 addresses before IPv6 addresses, which means that IPv4 is used if the remote host has both IPv4 and IPv6. Here's an example: $ getent ahosts www.debian.org 86.59.118.148 STREAM www.debian.org 86.59.118.148 DGRAM 86.59.118.148 RAW 2001:858:2:2:214:22ff:fe0d:7717 STREAM 2001:858:2:2:214:22ff:fe0d:7717 DGRAM 2001:858:2:2:214:22ff:fe0d:7717 RAW I see the same behavior in chromium and iceweasel. If I go to http://ip6.me/, I see my IPv4 address instead of my IPv6 address. If I click "IPv6 only Test" I get my IPv6 address (http://ipv6.whatismyv6.com/). My ifconfig output looks like this: eth0 Link encap:Ethernet HWaddr 00:24:81:18:a7:9e inet addr:192.168.1.195 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: 2002:d567:c828:1:224:81ff:fe18:a79e/64 Scope:Global inet6 addr: fe80::224:81ff:fe18:a79e/64 Scope:Link That is, I have a NAT'ed IPv4 address and a global (non-NAT'ed) 6to4 IPv6 address. The actual 6to4 relaying is done by my router. ping6 and browsing IPv6-only domains (e.g., ipv6.google.com) work fine. I have not modified /etc/gai.conf which is empty (except for comments). -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: i386 (i686) Foreign Architectures: amd64 Kernel: Linux 3.2.0-3-686-pae (SMP w/2 CPU cores) Locale: LANG=sv_SE.utf8, LC_CTYPE=sv_SE.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages libc6 depends on: ii libc-bin 2.13-35 ii libgcc1 1:4.7.1-6 Versions of packages libc6 recommends: ii libc6-i686 2.13-35 Versions of packages libc6 suggests: ii debconf [debconf-2.0] 1.5.45 pn glibc-doc <none> ii locales 2.13-35 -- debconf information excluded -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
