Want a free NZNOG 2014 conference ticket?
by Dean Pemberton 06 Jan '14

06 Jan '14

Krystal is looking for one or 2 more volunteers to help with registration and pack up. Duties will be - manning the registration desk on Thursday Morning (8am - 9.30am) and helping pack up gear to be shipped back in INZ on Friday after conference ends (4.00 - 6.00). If you put your hand up then we're happy to comp you a ticket, they may miss a couple of talks - but you should still manage to attend the bulk of the conference. If you're interested then please email krystal(a)internetnz.net.nz and let her know. If there is a huge influx of interest then some advanced algorithm will be used to determine those accepted. =)

by Sebastian Castro 05 Jan '14

05 Jan '14

Call for Presentations - DNS-OARC Spring Workshop, May 2014 Next OARC Spring Workshop will take place in Warsaw, Poland on May 10th and 11th, the weekend before RIPE68. OARC is requesting proposals for presentations, with a preference for DNS privacy and confidentiality work and ideas, and DNS over alternative (non UDP) transports. This workshop continues OARC's tradition of having meetings include a strong operational component. Presentations from DNS operators are particularly welcome. We'll also gladly accept talks from DNS researchers, as well as any other DNS-related subjects such as tools, visualizations and data analysis. If you are an OARC member, and have a sensitive topic you would like to present for members-only, we will accommodate those talks too. Adopting practice from other conferences, a section of lightning talks will be added for short presentations. Workshop Milestones * 20 December 2013, Call for Presentations posted * 6 January 2014, Open for submissions * 1 March 2014, Deadline for submission * 28 March 2014, Final Program published * May 9 2014, Final deadline for slideset submission Details for abstract submission are be published here: https://indico.dns-oarc.net/event/workshop-2014-05 If you consider submitting a presentation, please let the Programme Committee know in advance to help us organize the presentations tracks. You can contact the Programme Committee: https://www.dns-oarc.net/oarc/programme via submissions(a)dns-oarc.net if you have questions or concerns.

CARDIGAN implements RPKI - Cleanliness of prefixes onWIX
by Dean Pemberton 05 Jan '14

05 Jan '14

Hi All, CARDIGAN has just finished implementing RPKI Origin Validation on its WIX peering connection. What this effectively does is finds out if ASs are permitted to announce the IP addresses that they are advertising to the exchange. CARDIGAN then makes a decision on wether to allow invalid announcements to be turned into OpenFlow rules. So I thought you'd all be interested in the state of the prefixes on the exchange. The following table has removed all the routes for which no RPKI information was found. This leaves two conditions: Lines which start with a "V" have a valid RPKI ROA. That means that the AS originating the prefix has been explicitly authorised by the IP resource owner to do so. Likes which start with an "I" have an RPKI ROA which is different to the route seen. This means that the AS originating the prefix has been explicitly disallowed from doing so by the IP resource owner. These are explicit authorisations as the IP Resource owner has had to go to an RPKI trust anchor (normally the RIRs) and request certification of the ASs allowed to originate the prefix (or subnet of the prefix). For most of us (who are APNIC members) this is as simple as logging into the MyAPNIC portal and creating an ROA. APNIC handles everything else for you. Anything that turns up as an "I" on this list, I'm going to be looking at pretty carefully before I prefer into the CARDIGAN network. Anyone with more questions about RPKI, how it works, what it means, how to get it going. Feel free to post/email me.

NZNOG 2014 Update
by Dean Pemberton 16 Dec '13

16 Dec '13

Hi Everyone. Registrations have been open for the conference for a while now and I'm pleased to say that they are at an unprecedented level for this time of year. Given that we've only just released the program, thats an outstanding achievement. With some great help from InternetNZ the conference is shaping up to be as awesome as usual. First up I'd like to thank the sponsors who have signed on thus far: Go Wireless - Gold Network Hardware Resale - Gold Vocus - Gold CityLink - Gold GKC - Silver Brocade - Silver Arbor Networks - Silver APNIC - Silver Extreme Networks - Silver Kordia - Bandwidth Sponsor We have more slots open for sponsorship as well as the much coveted Platinum sponsor position. If you would like to ensure that your organisation gets high visability at the event then contact sponsorship(a)nznog.org for a sponsorship pack. We know that the program is an important part of convincing your organisations that you need to attend. This year we've got a wide range of speakers lined up along with some great Workshops and tutorials. Program: International Keynotes: Tom Paseka (CloudFlare) - NZ Perspectives from a global CDN Roland Dobbins (Arbor Networks) - TBA Conference Presentations: Geoff Huston (APNIC) - Measuring DNSSEC Jamie Baddeley (Citylink) - NZIX2/Citylink SDN Sam Russell (REANNZ) - Building a better Skype with WebRTC, SIP, and ENUM Barry Brailey (DNC) .nz DNSSEC programme Jean-Sébastien Fontana (Extreme Networks) - Introduction to TRILL Gerard Creamer (Netspace) - Experiences with dual A records vs anycasting Beatty Lane-Davis (Cyan) - SDN & NFV Michael Fincham (Unleash) - RPKI Peter Gent (MBIE) - 5GHz Wireless Links Jan Jorz (ISOC) - BCOP Project Quintin Russ (SiteHost) - IPv6 deployment in the cloud InternetNZ Update APNIC update WAND update Lightning Talks Workshops: Network Infrastructure Security BGP Routing Tutorials: OpenDNSSEC Installation and Configuration (1/2 day) SDN/OpenFlow Installation (1/2 day) Mikrotik Routing (full day) APNIC Internet Resource Management (1/2 day) We'd suggest you register now. At least this side of Xmas. Flights, Accommodation etc will likely be easier and cheaper the sooner you do it. Better than doing it in a panic in mid January. For more information on how to register, head off to http://www.nznog.org/register See you all there. Dean

Keeping it local
by Martin Kealey 15 Dec '13

15 Dec '13

I have a question which I'm hoping the NZNOG community can help me with. Within NZ, what is the maximum number of hops from APE to any consumer's interface device? (smarty-phone, ADSL modem, whatever)? Or more pragmatically, let's say the 99th percentile, as in, fewer than 1% of customers are more than X hops away from APE. If this information is already available, I'd appreciate a pointer, otherwise... If you are an ISP could you give me an indicative number of hops from APE to your customers' CPE. If you can include a prefix length reflecting the number of affected customers that would help too. (Ideally the maximum across all your customers, but if you have a few oddball customers with longer paths, just the 99% will do.) If you're an ISP customer and would like to tell me your hop-count to APE (counting from your CPE, not from your computer) and your ISP's name, that would also be appreciated. Replies off-list and I will summarize back to the list. Here's the background: I'm investigating ways of limiting traffic so that it does not leave New Zealand, that can be configured on an application-by-application basis. Obviously if one has an upstream to "global" and a separate upstream to APE or WIX, then it's simple to filter traffic at those egresses. However for the average end-user, it's difficult to get multiple VLANs to their provider, let alone multiple physical links. In an ideal world, one would simply set some QoS bits and your upstream would understand them and do the filtering based on *their* egress, but in practice I haven't heard of any suppliers offering such a service. So I'm looking at DIY options ... In particular, I'm looking at setting the TTL on outgoing packets. We know how many hops it is from "our" hosts to APE, and I guestimate no more than 2 hops from a consumers border device (modem, whatever) to their client devices; So far it looks like setting the TTL so that it's down to 5 at APE will mean most of NZ is reachable, and most of the rest of the world isn't, assuming the international provider is as many hops from me as APE. But I'd really like to get a firmer idea of "how much of NZ will be unreachable given an egress hop limit of X?" (The idea is to find X where the list of exception prefixes is small enough to manage manually, while still blocking the majority of foreign traffic.) What I'd like to find out from the NZNOG community is the distribution of customers at various hop-counts from APE. -Martin

ISC/F-Root has returned to APE...
by Peter Losher 11 Dec '13

11 Dec '13

FYI - the Auckland node of F.ROOT-SERVERS.NET has been offline for the past couple of years due to HW failure, access issues @SkyTower, changes with our hosts (contacts and access to said data center). I am happy to report that the node is finally back online and advertising F's prefixes to the APE fabric as I type... So come and send your DNS root server queries locally instead of sending them off-shore. We are AS23710 @APE, so if you don't peer with us already, pop us a note at peering(a)isc.org. Yes, Telecom NZ, I am looking at you. Yes, you... (a guy can dream, even if it is hopeless) ;) There are many folks to thank as ISC could not do it alone including: - NZRS (Jay, Sebastian and Dave) for sponsoring the new server gear. - APNIC for sponsoring the new routers. (sorry to see the old Juniper kit go though) - Sebastian and Mike Jager for dealing with my numerous remote hands requests from the other side of the world. - The Kiwi Internet Mafia (Joe Abley, AJ, Jonny) for their support and access to their contacts to keep things moving. - Vodafone NZ and FX Networks for (now redundant) transit over IPv4 and IPv6. - Our peers at APE that have put up with us for being down so long... :) O.k., commercial over; back to serving packets again. Best Wishes - Peter -- [ plosher(a)isc.org | Senior Operations Architect | ISC | PGP E8048D08 ]

Web Servers: Dual-homing or DNAT/Port Forwarding?
by Christoph Berthoud 10 Dec '13

10 Dec '13

Hi All, I'm curious to know which of the following methods is more widely used/accepted today for publishing web servers to the Internet. 1) Dual-home the server - place one NIC on the internet and a second NIC on an internal network for administration, or 2) DNAT/Port Forward my external IP to my internal IP 3) Both - Dual home the server onto two private subnets (external/internal) and DNAT/Port Forward the public IP to the external subnet IP In either case: a) I will be hiding behind a dedicated firewall appliance and not relying on the OS firewalls b) the internal network will still be in its own subnet firewalled away from the rest of the network c) Only HTTP/HTTPS will be permitted from the internet, no RDP, SSH etc d) I will be deploying IPv6 to this machine in the next 12 months which makes option 1 more attractive I personally like option 1 but I'm looking to see if theres any facepalm reasons I shouldn't do it this way. Happy holidays! -- Thanks Christoph
