Package: libc6
Version: 2.7-6
Severity: normal


Since one of the last updates I noticed my system stoppend using ipv6.
I seam to have tracked that problem down to the new RFC3484 and
/etc/gai.conf functionality...

Actual situation, local machine:

eth2      Link encap:Ethernet  HWaddr 00:13:ce:36:7f:f5
          inet addr:157.161.57.67  Bcast:157.161.57.79  Mask:255.255.255.240
          inet6 addr: fec0::213:ceff:fe36:7ff5/64 Scope:Site
          inet6 addr: 2002:5448:894d:0:213:ceff:fe36:7ff5/64 Scope:Global
          inet6 addr: fe80::213:ceff:fe36:7ff5/64 Scope:Link

Trying to connect to any IPv6 host not on the local network:

~$ telnet gintonic.woody.ch
Trying 157.161.57.2...
Trying 2001:4060:dead:beef:213:d3ff:fea8:8ef8...

Why is IPv4 being prefered? As I understand if both is possivle, IPv6 should be prefered.

Same test from a 'etch' machine in same subnet:

ii  libc6                        2.3.6.ds1-13etch4            GNU C Library: Shared libraries

# telnet gintonic.woody.ch
Trying 2001:4060:dead:beef:213:d3ff:fea8:8ef8...
Trying 157.161.57.2...

That's the order I expect.
