IPv6-enabled OpenCSW mirror

My home network has native IPv6 with radvd running on the router. Any host connected to it automatically gets an IPv6 address. (Unless it’s a Solaris zone, but that’s another story.) For a reason I haven’t worked out yet, all IPv4 traffic on my downlink seems to be throttled to 60kB/s. However, when downloading over IPv6, I’m easily getting 150kB/s or 200kB/s.

When setting up a Solaris 10 system (this time using kvm), I’m getting an IPv6 address straight away:

bash-3.00# ifconfig -a6
lo0: flags=2002000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL> mtu 8252 index 1
inet6 ::1/128
rtls0: flags=2000841<UP,RUNNING,MULTICAST,IPv6> mtu 1500 index 2
inet6 fe80::5053:ff:fe13:9457/10
ether 52:53:0:13:94:57
rtls0:1: flags=2080841<UP,RUNNING,MULTICAST,ADDRCONF,IPv6> mtu 1500 index 2
inet6 2001:770:18d:0:5053:ff:fe13:9457/64

(the ‘rtls0’ interface is a name for a rtl8139 NIC)

I want to use an IPv6-enabled OpenCSW mirror! Such as ftp.heanet.ie.

You may want that too. Edit /etc/wgetrc (or /opt/csw/etc/wgetrc if you’re using OpenCSW wget) in your Solaris system and add a line:

prefer-family = IPv6

…and…

bash-3.00# pkg-get -U

wget will now try to use IPv6 where available. When IPv6-enabled site is not there (no AAAA record, for instance), it will fall back to IPv4.

UPDATE: Putting network interface in a (VirtualBox 1.6.4) virtual machine into promiscuous mode does in fact make the interface accept icmp6 traffic.

UPDATE (2009-03-11): Added information about OpenCSW wget configuration path.
