jc blog - tales of a modern-day nomadic hunter-gatherer

Follow jcomeau_ictx on Twitter This is the weblog of Intrepid Wanderer. You never know what you might find here; graphic descriptions of bodily functions, computer programming secrets, proselytizing for the antichrist, miscellaneous ranting and kvetching, valuable information on living off the land... if you don't share my rather weird interests you may want to try slashdot instead.

You can consider my Del.icio.us links an extension to my blog, as are my LifeTango goals and my other to-do items. My to-buy list is also public, but only for sharing any useful ideas that might be there; I'm not requesting charity, neither do I offer it.

You can find me easily in google searches, as jcomeau, jcomeau_ictx, or jcomeauictx. There are lots of other jcomeaus, but AFAIK I'm the only jcomeau_ictx out there so far.

If you want to comment on anything you see here, try the new Facebook comments, reachable by clicking the "[comment]" link at the end of each post. If for some reason that isn't working, go ahead and email me, jc.unternet.net. You know what to do with the first dot. Make the 'subject' line something reasonably intelligent-looking or it goes plunk! into the spambasket unread.

finally got ipv6 working on the home network, using tunnelbroker.net and a Linksys router running DD-WRT. at first my netbook wasn't getting an IPv6 address from the router's radvd, but switching from the brcmsmac to ath9k, then rebooting, may have been what solved it. then again, it may have been just the reboot.

but since I don't have ip6tables on the router yet, I had to shut it down with ip link set he-ipv6 down. can't risk the Windows systems getting cracked. [comment]

after two days of spending zero, I went to Grocery Outlet and blew $13.21. for tonight: half a sixpack of Barrel Trolley nut brown ale, about $2.15; small wild-caught salmon steak, $2.31; and an avocado for $.99. [comment]

having a hell of a time setting up a tunnelbroker address. it's up, and it sorta kinda works, but when I ping it I get the reply plus a "destination unreachable" error. going the other way, pinging another differently-configured server, I watch the problem with tcpdump:

22:22:23.957266 IP 216.218.224.42 > 207.210.74.124: IP6 2001:470:1f0f:12a7::1 > 2002:cfd2:4a7c::1: ICMP6, echo request, seq 4, length 64
22:22:23.957320 IP 207.210.74.124 > 192.88.99.1: IP6 2002:cfd2:4a7c::1 > 2001:470:1f0f:12a7::1: ICMP6, echo reply, seq 4, length 64
22:22:24.017891 IP 216.218.224.42 > 207.210.74.124: IP6 2002:d8da:e02a::1 > 2002:cfd2:4a7c::1: ICMP6, destination unreachable, unreachable address 2001:470:1f0f:12a7::1, length 112

in the above, 216.218.224.42 is the ipv4 endpoint of problemserver's tunnel, 207.210.74.124 is goodserver's ipv4 address, 192.88.99.1 is goodserver's tunnel endpoint, and 2001:470:1f0f:12a7::1 is an address in problemserver's assigned /64 from tunnelbroker.

the answer is probably staring me in the face, but I don't see it. any ideas? [comment]
