  Squid 3.1 (with ipv6 support) lands in debian

Last night I got an old box with an arm cpu mostly working. I used to use it as a dns and dhcp server back when wireless routers were lame. It's a TS7250 - a great little 200 Mhz ep9302 arm box, eating only 300mw of power (less with power saving on!), and now that I live deep in the boonies I figured I could retask it, maybe make it run email and squid, etc. Aside from floating point, it's probably about as powerful as a pentium II, and I used to hang dozens of email users off of one of those. I just need to support me and my roomate. 300mw sounds about right.

But it's gotta speak ipv6 to talk email in my world. So, first up was getting an ipv6 enabled and modernized 2.6.29 kernel... which I mostly have now, thanks to these patches for the ts-7250 which bring it up to date, enable 64MB of ram, and a host of other features on this board that I didn't even know existed.

Next was that all-important ipv6 enabled squid server. I've been building my own squid server with ipv6 support ever since the OLPC project started, and I'm kind of tired of it... and figuring out how to get it to cross compile for debian on the arm eabi I was NOT looking forward to.

This morning I downloaded the Squid 3.1 release and was preparing to get it built, looking over the bug reports in debian and in ubuntu and dreading having to build my own version for the arm box and...

I hit reload...

And Squid 3.1, with ipv6 support, landed in debian this morning. How cool is that?

Sometimes the net works in weird, wonderful, ways.

Were I half as clever as I like to think I am; I would author a paper titled:

"The Fallacy of IPv6: A contemporary review of Jevon's Paradox"
 
I finished the first pass at getting that tiny arm box working yesterday. (if you have an ipv6 tunnel, it's at http://pocobelle.sjds.teklibre.org )

It's running bind, apache, ipv6, postfix, spamassassin, clamv, cricket AND inn, drawing so little power from my UPS that it doesn't even register.

Of these, bind is the biggest memory pig by far, eating over 32MB of ram to run. postfix and apache aren't even in the same league... I remember when the whole internet fit into a hosts.txt file...

cpm: re ipv6 - the future is here, it just isn't evenly distributed yet. I'm totally loving seeing mail get *right* to my laptop, with one intermediary at most. I love having real DNS again. I love being able to run my own web server again...

You can get a dynamic ip tunnel by doing an apt-get install tspc, and a static one (with a /48's worth of real IPs) via any of a huge number of providers (I'm using tunnelbroker.net)

I find it really hard to invoke jevon's paradox with a /48.

If I have to MAKE the future happen all by myself, I will, but it would be nice to convince others that this is the right path and have a few helpers.......

IPv4 is the IPX/SPX of the 201Xs... the internet is broken and getting worse. Ipv6, for all it's flaws, is the answer.
 
"I find it really hard to invoke jevon's paradox with a /48."

Precisely my point. This is why Jevon's applies.
 
In that vein, I do need to get a working comprehension of it. It is inevitable. Has been for over a decade, will be still in another decade maybe.

"If the Internet did not exist, man would have invented it."

You can quote me on that.

I fear that original binary (morse code) will actually be more handy in the future than addressing protocols big enough to hide instruction sets.
