Prep for Tomorrow with an IPv6 Testbed - page 3

On the Horizon...

The fine folks at Hexago host a free service to allow us to play with real live IPv6. (This used to be on freenet6.net, for you oldtimers.) You need a static, routable IP address on your Internet gateway. First sign up for an account. Then download and install the client software, tspc-2.1-src.tgz. Stick it any directory you like:

$ mkdir -m 755 ~/tspc
$ cd ~/tspc
$ tar zxvf tspc-2.1-src.tgz
$ cd tspc2
$ make all target=linux

Then go to /tspc2/bin. Open tspc.conf.sample, and add the login and password for your Hexagon/Freenet6 account. Then comment out "server=anon.freenet6.net", and uncomment "server=broker.freenet6.net." Change the filename to tspc.conf.

Next, while you're still in /tspc2/bin, su to root, and start up your IPv6-over-IPv4 tunnel:

# ./tspc
tspc - Tunnel Setup Protocol Client v2.1
Initializing (use -h for help)

Connecting to server with reliable UDP
Got tunnel parameters from server, setting up local tunnel
Going daemon, check tspc.log for tunnel creation status

Well, OK! The connection is successful. Forget reading boring old logs � fire up a Web browser and connect to any of the sites listed above in "Are You Already IPv6-ed?" The KAME site will display an arthritic dancing turtle. Aerasec's main logo will do gentle gyrations. Have some patience, because tunneling IPv6-over-IPv4 is slow.

Take a look at the output from /sbin/ifconfig, you'll have a new section:
