Hi List After Mark's announcement about removal of Iconz public ntp I thought I should check my ntpd configs. Can anyone from Vodafone give an update on tk[1-4].ihug.co.nz? After many mergers and acquisitions it occurs to me that perhaps these could be dusty machines under someone's desk that could disappear one day without announcement? Any official comment? Is there an official webpage about them? Regards, Joel van Velden

Software Defined Networking (SDN) Presentation
by Jay Best 07 Apr '14

07 Apr '14

Hey is anyone else going to this? I haven't seen many of you guys from NZNOG in ages, so would be good to catchup for old times sake! Cheers, J *Software Defined Networking (SDN) Presentation* Auckland Tourism, Events and Economic Development and Massey University invite you to an informative and engaging presentation by world leading New Zealand expert Mr. Josh Bailey from Google around SDN research in New Zealand and beyond. SDN has been generating a lot of press in the network industry and research worlds. While a community has arisen to energetically debate what SDN is? There are concrete research efforts and deployed systems exploring the implications of separating control and data planes. These include Google's B4 network (which connects Google data centers together) and uses OpenFlow and CityLink's efforts in New Zealand to produce an SDN controlled Internet exchange. This presentation will describe some recent research both here in NZ and in the US, including work at REANNZ and Victoria University on building and deploying an open source SDN controller and experiments including RPKI. Date: Monday, 14th April 2014 Time: 4.30pm - 6.30pm Venue: Room OR 4, Building 102 Massey Albany Campus Gate 4 Eastbourne Road, Old Albany Highway. Cost: Complimentary RSVP: Shona Alo (s.alo(a)massey.ac.nz) if you would like to attend

Bitstream 3a DHCP manipulation
by Dave Mill 07 Apr '14

07 Apr '14

Hi all I posted a few weeks ago about MAC limits on Bitstream 3a connections. This is related to that. This is a UFF Bitstream 3a connection. I've discovered that a customer's only complaint with a Bitstream 3a connection from us is that DHCP doesn't work over this. I've obtained some pcaps from both ends and I can see the following changes occurring to a DHCP Request: 1) The transaction ID is changed 2) Option 82 is added. More specifically, sub-option 1 Agent Circuit ID is present and has a valid length. sub-option 2 Agent Remote ID is present, has a length of 0 and no content which wireshark doesn't seem to like much. I've had a brief read of RFC3046 and I can't really tell if its valid to have a sub-option with a length of 0 or not. https://tools.ietf.org/html/rfc3046#page-8 I never see any DHCP ACKs coming back from the customer's DHCP server. I've had a read of some of UFF's Bitstream3a docs and can't see any mention of DHCP. I can see in one of our initial requests we had to fill out we can choose to have DHCP Relay Agent Functionality but this seems to be related to Bitstream2 only and also this defaults to be disabled. I don't know what DHCP server the customer is using right now but I hope to find this out soon. Questions for anyone with more experience in this than myself: -Can changing the DHCP Request transaction ID cause issues? -Has anyone come across DHCP servers not liking option 82 being set, or not liking sub-option 2 having a 0 length? -Has anyone successfully used DHCP across a Bitstream3a connection? How about a UFF Bitstream3a connection? -Am I missing anything obvious? Obviously I might end up talking to UFF over this but I just want to see what others on the list know before doing so. Again, I don't really want to debate the wisdom of plugging two LANs in over a Bitstream3a connection. Cheers Dave
