Internet at the conference
by Nathan Ward 22 Jan '17

22 Jan '17

Hi, I’m in Tauranga for the week for work, and am staying at Trinity where the conference is being held. I’m attending on Thurs/Fri (now that I’ve registered having prev. forgotten haha). The wifi here, at least in the rooms, is abysmal - I’ve stayed here a few times before, and it’s always the same - and is the same now. Anywhere from 10-25% loss, and 100-500ms std-dev when ARPing the gateway at various times. I note that there’s an NZNOG SSID - is this using the same wifi equipment? MACs seem similar, but reception is poor, so maybe it’s just in the conference area? If you have an ethernet adapter, you can plug in to the lower of the two RJ45 holes in your room, get 100mbit link, auth with the captive portal, and get 2% loss instead, much better RTT though. Seems I can get around 8mbit/s out of it. Of course, if this is how it is without a bunch of nerds, it’s not going to get any better at the tail end of the week ! Long story short - unless the conf. organisers are sorting something else out, bring some 4G if you need to be online reliably - 4G on VFNZ seems to be OK here and has been a life saver for me when staying here in the past. Cheers, -- Nathan Ward

Does anyone know what the story is with caching Amazon Prime traffic? Do they have an ISP programme for rolling out caches like the Netflix Open Connect Appliances?

looking for rack mount ears - HP 1920 series
by Terry Hughes 18 Jan '17

18 Jan '17

sorry, I know this is way off-topic, but I'm out of options. I need to re-work a small rack with a few 1920 OfficeConnect switches in it, and the original installer threw out the mounting ears and just sat the switches on top of some old equipment. The holes don't match any of the generic mounting kits I've got, and HP don't list the mounts as spares. Does anyone have a couple of mounting kits, or at least the ears? Fair compensation no problem. I'm in Wellington, but know how couriers work... thanks, Terry (long time lurker etc) 021 575715

Supporting RIPE Atlas
by Sebastian Castro 15 Jan '17

15 Jan '17

Hi everyone: On preparation for NZNOG 2017 next week, I'd like to pitch the RIPE Atlas project to this audience. RIPE Atlas https://atlas.ripe.net/ is global measurement network composed by hundreds of lightweight probes, that allow their users to run a variety of network measurements. The probes are small, powered by USB, and let you run Ping, Traceroute, lightweight HTTP, DNS lookups, etc. It provides the convenience of running measurements from different networks, very useful for troubleshooting and monitoring, as well as research. There are 82 active probes in New Zealand, and we would like to cover most of the active ASNs in the country with a probe. NZRS uses RIPE Atlas for some of our research work, like Detecting if NZ ISP are doing DNSSEC validation <http://blog.nzrs.net.nz/dnssec-validation-at-spark-nz/> or testing local ISP resolvers for centricity <http://blog.nzrs.net.nz/resolvers-centricity-detection/>, as well as our efforts to map the Internet topology of NZ that will be presented at the conference. Some NZNOG members are RIPE Atlas ambassadors, like Dean Pemberton or myself, we can get you a probe if you are interested on hosting one. I'll bring a few to Tauranga next week, feel free to contact me if you want one. If there is more demand than available probes, I can get a bunch directly from RIPE and post them to you later. Kind Regards, -- Sebastian Castro Technical Research Manager NZRS Ltd. desk: +64 4 495 2337 mobile: +64 21 400535

a bufferbloat-less christmas
by Dave Taht 22 Dec '16

22 Dec '16

I gave a talk at nznog about 2 years ago about bufferbloat and the fixes we had planned for it. I'm pleased to say that we've got it mostly fixed in the Linux kernel at this point. did the NZwrt idea ever get traction? In particular, the wifi fixes (fq_codel at the mac layer, and airtime fairness) have today, entered lede (formerly openwrt). There's full support for the ath9k and partial support for some ath10k chips. Builds should be popping out in a few hours. Most of these patches are now in the linux 4.10 mainline - and ATF is scheduled for 4.11. The sqm-scripts (in lede and openwrt, which also work on mainline linuxes) have long enabled fixing dsl, cable, fiber, ethernet - but *are not* required to fix wifi - with these patches, "wifi just works!" with far less bloat and more concurrency. There's a ton of ath9k/ath10k using products out there supported by lede. The Turris Omnia has all the sqm-scripts, fq_codel, and the ath9k/ath10k stuff either in it now, or rapidly pending. There's also some good stuff in the dsl-aware-autoconfig-ing http://evenroute.com/ (but not the wifi stuff as yet). A lot of people are liking the edgerouter-x... ... And there are dozens of other firmwares and products using fq_codel functionality - notably the ubnt edgerouter calls it what it is, but you'll see it also under names like "adaptive qos", and so on. For a good bit of research as to how fq_codel helps on slow connections (in this case, in australia across NBN's speed tiers), see: http://caia.swin.edu.au/reports/161107A/CAIA-TR-161107A.pdf for some details what went into fixing wifi, see: https://lwn.net/Articles/705884/ So... Have a bloat-free christmas! fix it for yourself, and then a friend, or two. My testing while I was in NZ last time seemed to indicate no particular tuning was needed for your country, but I remain curious as to what happens when you deploy this new stuff, there - and, if, over the last 2 years, you had been. Wish I was there, myself. Looks nice and warm. -- Dave Täht Let's go make home routers and wifi faster! With better software! http://blog.cerowrt.org

Hi, Is anyone else in NZ seeing their pool.ntp.org traffic volumes up by an order of magnitude over the last few days? 20mbps+ seems like quite a lot of NTP. Cheers, -- Lincoln Reid Head of Networks ACSData - AS18119 lincoln(a)acsdata.co.nz Phone: +64 4 939 2200 Fax: +64 4 939 2201

Certifications
by Lesley Longhurst 14 Dec '16

14 Dec '16

Hi all, As an all-purpose leading network bod for my company, what's a good certification strategy? I deal with a wide range of stuff from local LANs to international backbones, and it's high time I got myself a piece of paper to "prove" that I know some stuff. Is CCNA still a good starting point?
