APNIC IPv4 Address Pool Reaches Final /8

That was quick…

We wish to inform you that as of Friday, 15 April 2011, the APNIC pool reached the Final /8 IPv4 address block

So, everybody ready for IPv6 yet?

Announcing the IcedTea Buildbot

Over the last few weeks Xerxes and I have been experimenting with a buildbot setup which you can see at: http://builder.classpath.org/icedtea/buildbot/waterfall

It does various builds on ia32, x86_64 and arm buildslaves whenever a commit is pushed to icedtea6, icedtea7, icedtea-web or the testrepo. The slaves also test various alternative runtime setups (cacao, shark, zero). By doing continuous builds on all these various setups we hope to keep the projects green at all times.

More information and how to help extend the current setup on the mailing list.

Freedom Box Project

The Debian Freedom Box Project has the cutest logo. I want one!

There is now also the The FreedomBox Foundation. They are raising some money through their “Push the FreedomBox Foundation from 0 to 60 in 30 days” initiative.

Does anybody have recommendations for which of the targeted plug devices hardware to get?

OpenJDK governance Score Card

Simon Phipps made a handy dandy OpenJDK governance Score Card. Taking the proposed OpenJDK Community Bylaws draft proposal, and measuring it against the Open-By-Rule Benchmark. So you can quickly see how the current draft is doing against the ten benchmark rules (“open”, “meritocratic”, “oligarchy”, “license”, “copyright aggregation”, “trademark”, “roadmap”, “co-developers”, “forking” and “transparency”). Scoring goes from -10 till 10…

First thoughts on OpenJDK Community Bylaws

I am not really sure what to think about the proposed OpenJDK Community Bylaws. There are some very obvious issues in there:

• The governance board is responsible for sufficient infrastructure for the members, but doesn’t have any resources for that.
• There is a direct tie to the JCP and the platform JSRs, but those are currently published under license terms that are GPL-incompatible (See Moving Java forward through the JCP?).
• Members are those that assign all rights to Oracle. (See Trusting companies with your code… and Oracle tries to destroy free java – now what?).
• It doesn’t define the minimum (GPL) copyright, trademark and patent grants as used by the project (although it does mention it should be open-source).
• The board consists of Oracle and IBM appointees, with only a minority for independent candidates (the second and third largest corporate contributors, Red Hat and Google are not even mentioned.)

I have posted a longer analysis to the mailinglist.

Hope those blockers can be fixed, but there is a long way to go IMHO.

New GPG key

Finally created a new GPG key using gnupg. The old one was a DSA/1024 bits one and 8 years old. The new one is a RSA/2048 bits one. I will use the new one in the future to sign any release tarballs I might create.

pub   2048R/57816A6A 2011-01-29
      Key fingerprint = 47CC 0331 081B 8BC6 D0FD  4DA0 8370 665B 5781 6A6A

It currently is only signed by my old key (0x95ABF50C), so if you trusted that really was me, then you can be pretty sure the new one is also me. But it would be good to get some more people to confirm the transition. So if you happen to come to Fosdem next weekend and run into me, please exchange GPG key details to confirm each others identity. Full public key available from my homepage and on the various keyservers.

Who knew IPv6 would be this easy?

Obvious, with only hours till we run out of ipv4 addresses, I am a little late to the party, but it was ridiculously easy to get an IPv6 tunnel going so that I will be able to happily connect to all those new IPv6-only hosts in the future. It literally took just 5 minutes.

• On Fedora make sure you also run the network scripts on startup (it seems to default to NetworkManager only these days): chkconfig networking on.
• Look up your ISP IPv6 tunnel setup procedure (or if they aren’t yet, look for a public one like Sixxs, Freenet6 or Hurricane Electric).
• Punch in the ipv4 tunnel address and the ipv6 addresses provided into /etc/sysconfig/network-scripts/ifcfg-sit1.
• Add NETWORKING_IPV6=yes and IPV6_DEFAULTDEV=sit1 to /etc/sysconfig/network.
• Restart networking: sudo service networking restart.
• Done! You can now happily explore the IPv6 space: traceroute6 fedoraproject.org. And check http://test-ipv6.com/ to see your are ready for World IPv6 day.

Example /etc/sysconfig/network-scripts/ifcfg-sit1 file:

DEVICE=sit1
BOOTPROTO=none
ONBOOT=yes
IPV6INIT=yes
IPV6TUNNELIPV4=198.51.100.241
IPV6ADDR=2001:db8:10:a8c::2

Apparently things are even easier with 6to4 if you have a direct IPv4 address, but the above works even behind a NAT. The above doesn’t use all the fancy IPv6 features yet like providing automatic configuration for all your devices in your network. Such a tunnel will automagically provide you with at least 2^64 IPv6 addresses, and most likely you get a whole IPv6 /48 network meaning you will be getting 2^16 * 2^64 addresses (yes, that is more addresses than there are currently IPv4 addresses in the world!). But it is a nice start to make sure the future transition will be smooth.

See also /usr/share/doc/initscripts-*/ipv6-tunnel.howto and/or /usr/share/doc/initscripts-*/ipv6-6to4.howto for more information, including setting up all the fancy routing stuff on your local network if you want.
