Citylink's official Debian mirror (ftp.nz.debian.org) is apparently
again broken (not even listening on port 80 from where I'm sitting).
Would anyone be seriously interested in donating rack space, national
transit, or hardware to the cause of another official Debian mirror for
Having reliable and cheap access to free software projects like Debian
is critically important, and having a second official mirror seems like
a no-brainer to me.
I am very happy to donate my time to admin and monitor any equipment
provided for this, and to liase with the Debian project as required.
Perhaps Citylink could give us some insight in to the traffic levels
their existing mirrors see?
Merry Xmas all,
Anyone have a contact with Met Service IT provider/manager/ help desk?
http://www.metservice.com/ is running on complete go slow right now.
"Someone" needs to take a look at it.
This email has been checked for viruses by Avast antivirus software.
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
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),
for some details what went into fixing wifi, see:
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.
Let's go make home routers and wifi faster! With better software!
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.

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.
"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:
"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.
"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.

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).
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*
*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).
On Behalf Of The NZNOG Trustees
A heads-up that we have just opened registrations to the NZNOG 2017
conference in Tauranga. Details are here - http://www.nznog.org/nznog17 .
The conference is brought to you by Go Wireless NZ.
We have placed information regarding our current workshop and tutorials on
(Note, we might have some Grandstream phone training available on the
Wednesday as well - we are still firming up details)
We'd encourage people to register early for the tutorials and workshops as
some of these will have limited seats due to room availability.
Also, a reminder that early bird accommodation rates at the conference
venue will finish on December 12. Rooms are limited so again book your

A big thank you to all of our sponsors so far -
Hope to see you there!

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.
