Zone and host scanning by NZRS
by Jay Daley 09 Jun '13

09 Jun '13

Hi Sorry no beer here. Once a month we run a scan on the .nz zone to collect some IPv6 stats which are then provided to the IPv6 taskforce. This has been going for a while with no problems reported. We now plan to expand this scanning, partly to provide better stats on the use of DNS, like this above, and partly to help .nz run better. For example by detecting lame delegations and telling our registrars about this. As well as more DNS scanning we are also planning web site home page scanning for a very limited set of data related to .nz. For example finding out how many web sites in .nz use an SSL cert and would benefit from moving to storing details about these in DNS (see the IETF DANE WG for details - http://datatracker.ietf.org/wg/dane/charter/) Before we expand our scanning we've published a draft practice statement that sets out in detail what we are doing, why we are doing it and how we will do it and we want to hear what people have to say about that. We're not aware of anyone else creating and publishing a doc like this so this is very much new ground. The practice statement is here: http://nzrs.net.nz/dns/zone-and-host-scanning and we welcome comments on it. cheers Jay

Level One GVT-1000 SFP Media Converter in Trendnet TFC-1600 Fibre Chassis
by Alexander Neilson 06 Jun '13

06 Jun '13

I have a Level One GVT-1000 SFP to 1Gbps transceiver that looks like it should fit inside my TrendNET TFC-1600 chassis system http://www.flickr.com/photos/30026567(a)N04/8975140328/in/set-7215763398094… Top is the Level One and bottom is a TrendNET known compatible (but not useful in this situation) media converter. Has anyone got any experience using this hardware together? if so was is compatible / successful? I can use it stand alone if it won't work but I mainly want to avoid blowing it up. It would be a waste to use it stand alone (and a lot messier in the POP) if I can use the perfectly good chassis already waiting there for me. I will test it and come back with results if anyone else would like to know Off list replies are welcomed. Apologies if this breaches the charter. I had a read and felt it was close enough but happy to accept any feedback. Also if somebody knows of a supplier with in country supplies of chassis / standalone TrendNET and Transition Networks media converters (fixed laser and SFP Types) could they please let me know off list. Regards Alexander

Re: [nznog] Another Brocade question for my favorite mailing list

CES/CER can handle 1000 LSPs (lsp tunnels) before they stop making new ones. This can be an issue if you're letting your entire Cisco LDP domain pollute them. MLX would be a good order of magnitude larger but I don't have a specific figure. Have tested and used MTUs of 9000+ for VLL with no issues. Have tested and used MTUs of 4000+ for VPLS with some issues although this is the smaller CES platform and there may have been some feature gap in the Ironware version I was using at the time (MLX will have more features around this). QinQ works fine if you do port mode VLLs. Also have tested it working in a "raw" VPLS environment (port mode again). In case that’s not clear, port mode would be where you have all client ports as untagged. Raw mode every time if you ever want to do inter-op. This will set the VC-type to 5 and indicates that the port is transparent – from memory Cisco have this as a default in IOS.

-------- Original Message -------- Subject: [wellylug] Next meeting 17th Jun 6pm Date: 2013-05-23 13:01 From: Hugh Davenport <hugh(a)davenport.net.nz> To: Wellington Linux Users Group <wellylug(a)lists.wellylug.org.nz> Reply-To: Hi All, Thank you heaps for those who came to the social meetup the other week. I caught a few of you there when I finally arrived, and you seemed like a interesting bunch of people. I'm happy to announce that I have scheduled a technical meeting for next month. It will be on Monday 17th of June, at 6pm. The location is Level 3 Catalyst House. The front doors lock at 6pm, so best to come earlier, but there will be a number on the wall to get someone to come let you in. Future meetings will be on the third Monday of every month and will hopefully be pizza and beverages supplied (this one should as well!). I would be interested if anyone would like to present any material, let me know if you would like to. I will send a follow up closer with details of the talks on the night. tl;dr, come to lvl 3 catalyst house 6pm 17th june, email me to speak. Cheers, Hugh

Juniper and Brocade VPLS interop - any horror stories?
by Sam Russell 26 May '13

26 May '13

We've got a mix of Brocade MLX and Juniper MX chassis on our network and I'm working on getting VPLS standing up between them with LDP signalling (RSVP underneath for the base MPLS). Everything seems okay except for the odd quirk (Brocade can't do OSPF with jumbo frames, Juniper doesn't automatically strip VLAN tags when sending into the VPLS cloud) but otherwise it's standing up. I just wanted to see if anyone else has this sort of setup, and whether there's anything I should be looking for that might trip me up? My logic so far is as long as I don't try and make the Brocades do BGP then I should be safe, is this about right? Thanks in advance Sam

ISP provided routers
by Mauricio Freitas 23 May '13

23 May '13

So, which ISP is providing Tenda modem/routers to users? >From http://www.geekzone.co.nz/forums.asp?forumid=49&topicid=119152 "I installed a Tenda W150D at a friends place 2 weeks ago and their internet usage jumped from 200-600MB/day to 2-15GB/day." This had default DNS responder, open web administration and telnet visible from the WAN side.
