Jeff Forman put up a blog post on his website detailing how he got the Comcast IPV6 working through the trial. His setup explains exactly how to do this if you’re trying to get it to work on a Linux box, but not how to do this on your router and put it through your entire network. I’m running the custom DD-WRT build by crushedhat that gets IPV6 working, and have been using it with a HurricaneElectric tunnel for awhile. With the help of my friend whfsdude on Mozor I’ve been able to make this work. I can’t guarantee that it will work for you, and whenever you’re trying to install custom firmware on a router, you should be careful, as you can brick your router.

First off, you may want to read through Jeff’s post. You’re going to need your WANIP as he calls it, and you’ll need it converted into HEX.

To start with, in DD-WRT, you need to enable IPV6 and RADVD in Management. In the config section, put something like this:

interface br0 {
        AdvSendAdvert on;
        prefix 2001:55c:[WAN IP in hex form ####.####]::/64
        {
                AdvOnLink on;
                AdvAutonomous on;
        };
};

Then, in the Commands tab, you need to run the following for startup:

ip tunnel add he-ipv6 mode sit remote 69.252.80.66 local [WAN IP in ###.###.###.### form] ttl 255
ip link set he-ipv6 up
ip addr add 2001:55c:[WAN IP in hex form ####.####]::1/32 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip addr add 2001:55c:[WAN IP in hex form ####.####]::/64 dev br0

Additionally, due to the security vulnerability found in DD-WRT (patched already, but not in crushedhat’s build), you should run the following firewall script:

insmod ip6t_REJECT
ip6tables -F
ip6tables -A FORWARD -p tcp -i he-ipv6 --syn -m multiport --dports ftp-data,ftp,ssh,smtp,http,https,ntp,domain -j ACCEPT
ip6tables -A FORWARD -p tcp -i he-ipv6 --syn -j REJECT --reject-with adm-prohibited
ip6tables -A FORWARD -p udp -i he-ipv6 -m multiport --dports ntp,domain -j ACCEPT
ip6tables -A FORWARD -p udp -i he-ipv6 -j REJECT --reject-with adm-prohibited

That’s it. It was easy for me because I just swapped my he settings for the comcast ones that Jeff (and whfsdude) provided. It may not work for you, but good luck!

I just saw on the Google Voice blog that existing Google Voice subscribers now are getting three invites to give out to friends. I logged into my account this morning, no invites yet for me. But let the eBay sale of numbers begin again!

Auburn Tigers Game Countdown

My wife has always loved the Auburn Tigers, and for her, I’ve written the Auburn Tigers Game Countdown. It does a simple countdown to all their 2009/2010 football games. It gives the dates and, if available, the times/broadcast locations. There is an iPhone optimized version of the site as well (same URL). Finally, if you’re using OS X, open in Safari, then choose Open In Dashboard, and you can add it as a widget in your dashboard!

Where can this be found?

Trillian Astra 4.0 Released!

Richard — Sat, 15 Aug 2009 14:37:14 +0000

I’ve been alpha testing Trillian Astra 4.0 now since late 2007, and the finished product was finally just released! I’ve enjoyed using the alpha and have used it regularly since I got invited into the alpha, and can say that its a nice, stable, mature product now. I love the features of it, and hope they release the Mac OS X client soon too! Then I’ll use Trillian everywhere!

If you haven’t tried Trillian before, now’s the time! I love it!

You can download Trillian from the Cerulean Studio’s website. You can also see their release announcement here.

Welcome!
