AT&T postmaster
by 🔓Dan Wing 12 May '16

I help run a community machine (not for my employer) and we've been trying unsuccessfully for a month to get off AT&T's email blacklist; their automated systems claim we're off, but mail is still being blocked. Can an AT&T postmaster drop me an email to help work through this? Thanks. -d

--- mel(a)beckman.org wrote: From: Mel Beckman <mel(a)beckman.org> Accurate time to the millisecond is pretty much essential for any network troubleshooting. Say you want to diagnose a SIP problem. You collect transaction logs from both phones, the VoIP gateway, and the PBX. Now you try to merge them to derive the sequence of events. You NEED millisecond accuracy. ---------------------------------------- If all logs are sent to a unix server that does syslogd the log entries would go into the file in order no matter what timestamp is on them. scott

TeamNANOG youtube video seeding

First I am thrilled to see older Nanog meetings making it to youtube. Having said that can the people putting up the files put the Nanog meeting number in the title of the videos to make it easier to search and determine relevance? Thanks, james

third party single pole administrator regimes
by Fletcher Kittredge 10 May '16

10 May '16

This is outside plant related. Ignore if all you do is configure routers (not that there is anything wrong with that.) I would be interested in any network provider's experiences with third party single pole administrator regulatory regimes, such as Connecticut's. Please respond privately and I will summarize if there is any interest. thanks -- Fletcher Kittredge GWI www.gwi.net

I seem to recall that the positional accuracy is degraded to "on the order of 200 meters" when selective availability is enabled (and yes, they *can* do it by geographic area by careful turning on/off on each orbit of each satellite - devices are told the signal is degraded and can downvote that signal. So unless you're in the war zone, you'll just notice your device reporting a lock on 2-3 fewer signals). The upshot is that Grace Hopper told us about electricity moving a foot per nanosecond - which means that the time-domain jitter introduced is all of 600 nanoseconds or so. In other words, anybody using it to feed an NTP server will hardly notice on the millisecond level. If you're trying to use NTP to get microsecond stability, you'll notice - but you have enough *other* things to do correctly to do this that it shouldn't be an actual issue...

CALEA
by Justin Wilson 09 May '16

Does anyone have some up-to-date information on CALEA? https://askcalea.fbi.gov/ <https://askcalea.fbi.gov/> has a fair amount of broken links. The servicer provider registration is broken. The web-site has not been updated. Searches on FBI.gov and the FCC site just point back to askcalea. Are any of you still seeing CALEA requests on the voice or the data sides? What is the community hearing about CALEA?
