IPv6 PMTUD and OS-X
by Franck Martin 21 Aug '10

21 Aug '10

I'm trying to debug a pesky PMTUD issue with IPv6 on Mac OS-X 10.6. It happens only from home, on wireless, when connected to a mac aiport that does an automatic tunnel (teredo) to IPv6 backbone. There are IPv6 web site that I cannot browse until I lower the MTU to 1400. My Linux desktop in similar config works fine... With tracepath6, I see one end of the tunnel tells me MTU should be 1280, that's using linux tools. On mac, tracepath6 does not seem to exist, and I don't know what tool to use... I have seen scamper, but no binary... I have used wireshark (on mac) to detect the PTB packet, but don't see it either... I have not compared with my linux box... I'm doing this testing on the side, slowly because it is fun to try to understand what's wrong here... and I wonder if others have had similar issues... May be not fully on topic, but to bring it back to topic see this presentation: http://www.ripe.net/ripe/meetings/ripe-60/presentations/Stasiewicz-Measurem… Which states the PMTUD failure rate on IPv6 is about 1.9%

tool to wrangle config file changes
by Rogelio 20 Aug '10

20 Aug '10

Long story short, a really crappy vendor is being shoved down our NOC's throat. They have a horrid CLI (if you can call it that). People don't understand it (it's non-intuitive) and are screwing up things all the time. In the hopes of coping with the madness, some of us are looking to put together some sort of open source configuration management tool, such as RANCID. Any luck with this on non-standard equipment, particularly ones that DO NOT allow you to output something nice and "scriptable" (e.g. Cisco's "show running-config") (If not RANCID, any other suggestions?)

Numbering nameservers and resolvers
by Mike 19 Aug '10

19 Aug '10

Hi Folks, I am needing to renumber some core infrastructure - namely, my nameservers and my resolvers - and I was wondering if the collective wisdom still says heck yes keep this stuff all on seperate subnets away from eachother? Anyone got advice either way? Should I try to give sequential numbers to my resolvers for the benefit of consultants ... like .11, .22 and .33 for my server ips? Mike-

iPhone updates and required bandwidth
by JoeSox 18 Aug '10

18 Aug '10

Am I the only one that gets ticked off at the Apple iPhone update procedure and the amount of bandwidth it needs? Is there any secret I am missing to cut down on the required bandwidth needed for it (caching the update somewhere etc)? I don't own an iPhone (DroidX user here) and am unfamiliar with the update, all I know is it uses tons of BW. -- Thanks, Joe
