the report from the spambox front
by Randy Bush 30 May '12

30 May '12

as part of daily maint, where i read midnight logs from 20+ systems etc, i scan my spambox to make sure nothing falls through, and indeed catch one or two daily. but the spam is a source of great amusement. the internet is an wondrous place. the number of messages offering help for the serious bedbug problem has been dropping off recently. so there really is hope we are winning the war on the bedbug front. whew! fedex has so many dell xps laptops in transit to me that storing them looks to become a serious problem. anyone with some space in a storage locker near jimbocho? zita would really like to take advantage of all the free lobsters, but there is no red lobster we know of in tokyo [0]. as tokyo has everything, i am sure i could find one. but will they take an american coupon? a lot of russians are still trying to draw my attention to something which is obviously important. anyone out there read russian? i hope it is not something critical, like news on the bedbugs in moscow. we would love to take advantage of all the great clearance sales on fords, but the cost of garaging a car, especially a large one, in tokyo is a bit steep. randy, who has to run out to the accountant to keep up with all the fraud monitoring reports on my bank accounts and credit cards in the caymans.

Video streaming over IPv6
by Carlos Martinez-Cagnazzo 29 May '12

29 May '12

Hello, Can anyone comment on the availability of IPv6 video streaming services? I'm thinking about commercial, 'cloud'-based services a la U-Stream or Make.TV. I can roll my own, and will eventually do so, but having a commercial service that I could use would make my life so much easier :-) Any such service who is thinking about jumping on the World IPv6 Launch Day bandwagon and could use some (I'd like to think clueful) debugging can also contact me, we might be able to work something out. regards, Carlos

DNS anycasting - multiple DNS servers on same subnet Vs registrar/registry policies
by Anurag Bhatia 29 May '12

29 May '12

Greetings everyone! One small concern I wanted to discuss here. I know few registry/registrars which do not accept both (or all) name servers of domain name on same subnet. They demand at least 1 DNS server should be on different subnet for failover reasons (old thoughts). How one can deal with such case in case of anycasting setup which using one single subnet everywhere? Anyone else in community got similar issues? Thanks. -- Anurag Bhatia anuragbhatia.com or simply - http://[2001:470:26:78f::5] if you are on IPv6 connected network!

IPv6 security: New IETF I-Ds, slideware and videos of recent presentations, trainings, etc...
by Fernando Gont 29 May '12

29 May '12

Folks, * We've published a new IETF I-D entitled "DHCPv6-Shield: Protecting Against Rogue DHCPv6 Servers", which is meant to provide RA-Guard-like protection against rogue DHCPv6 servers. The I-D is available at: <http://tools.ietf.org/id/draft-gont-opsec-dhcpv6-shield-00.txt> Other IPv6 security I-Ds (such as, draft-ietf-v6ops-ra-guard-implementation) have been revised. Please check them out at: <http://www.si6networks.com/publications/ietf.html> * The slideware (and some videos!) of some of our recent presentations about IPv6 security are now available online. You can find them at: <http://www.si6networks.com/presentations/index.html> * We have also scheduled IPv6 hacking trainings in Paris (France) and Ghent (Belgium). You can find more details at: <http://www.si6networks.com/index.html#conferences> Our Twitter: @SI6Networks ipv6hackers mailing-list: <http://lists.si6networks.com/listinfo/ipv6hackers/> Thanks!
