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

pool.ntp.org traffic gone wild
by Lincoln Reid 19 Dec '16

19 Dec '16

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?

You may also wish to look at some of the online MOOCs. For example, a certified course (you pay for, and get your work verified etc) in Digital Network Essentials but you've probably moved on already a bit from this particular one. https://www.edx.org/course/digital-networks-essentials-imtx-net01x "All about the IP, TCP and UDP Internet protocols and their properties (quality of service, congestion management, etc.)" Or slightly more esoteric and off the original topic but still interesting to do is this one, put together by some fairly clued up people in their field: https://www.edx.org/course/cyber-security-economics-delftx-secon101x "We discuss and apply different economic models that help determine the costs and benefits of security investments in network security." Looking at this one from Ivan Pepelnjak, the six week course covers quite a bit and certainly would expose the holes in your current knowledge you need filling. Playing First Packet in a network symphony orchestra would be a good place to progress from should you require to learn the specifics and intricacies of certain equipment. http://www.ipspace.net/Building_Network_Automation_Solutions "In the hands-on part of the course you’ll build your own lab, either using virtual devices or physical gear. If you decide to go with the virtual device approach, you can choose between Arista vEOS, Cisco VIRL, Cisco CSR, Cumulus VX, Juniper vSRX or Juniper vMX." >From a business perspective, I think it is more useful knowing the why rather than just the how which is what certificates themselves often can't portray and may become very clear in an interview or stressed (the internets are broken...) situation.

Accommodation Early Bird Has Ended - Other Options
by Jesse Archer 12 Dec '16

12 Dec '16

Hi All, Just a heads up that the Trinity Wharf early bird pricing ended yesterday. Other options if you're looking to save some $$ are listed at the following link, but I wouldn't muck around (Tauranga is one of NZ's Summer hot spots). http://www.nznog.org/nznog17/venue Conference is selling nicely, if you're interested in the Workshop or Tutorials on offer, don't muck around - only a few spots left on those. Conference will finish at 4.30pm on Friday Jan 27. Your direct flight home options on this date include: *Auckland 5pm & 6:20pm* *Wellington 5:25pm* *Christchurch 4:00pm (transit via Wellington or Auckland available at 5:25pm or 6:20pm).* Check-in is 20 minutes before departure, I'd allow 30 minutes travel time from the venue to the airport just in case there is some peak Friday afternoon traffic on Hewletts Road (lots of traffic lights). Regards, Jesse Archer On Behalf Of The NZNOG Trustees

Strange issues in CHCH - Routing SYN Timeouts
by Brad Nightingale 01 Dec '16

01 Dec '16

Hi We are experiencing weird issues from out of our internet break out in CHCH. I don't want to drop our upstream in it so no names mentioned, but yes a ticket has been logged with them - this is just becoming urgent as it started . Since I have done this I have had reports from other IT Service Providers that say their customers are experiencing the same thing. Basically we can ping anything, but we cant web browse to wide range of certain sites (e.g. www.bnz.co.nz) - these would appear to be internationally hosted sites but I can't categorically state this. We are getting SYN Timeouts almost like there is async routing somewhere way up stream or some random MTU issue. I don't expect to have anyone solve the problem from this email, just a "yes there is an issue and we are experiencing it too and know XXX is working on it" would be helpful to know. Thanks Brad ________________________________ CAUTION: This communication, including any attachments are confidential.

Network Status/Anecdotes from #eqnz
by Joel Wirāmu Pauling 13 Nov '16

13 Nov '16

Hi all, Hope everyone is safe; thoughts are with everyone back home. As I went through the call list of friends and family this morning ; from the considerably less shakey Eastern Canada - my mind turned to work and network operators. Have a fairly rag-tag list of info mostly anecdotal from users on a variety of places (twitter/reddit/g+) about loss of services from ISP's (Nelson area seems pretty hard hit) Wondering how everyone's networks have held up and if there are any pain points, am sure the people at the forefront are already hard at work and sharing resources as required. But if there is anything people can and/or are willing to share it would be appreciated. -Joel
