Map/schematic over NZ Internet connectivity?
by Juha Saarinen 15 Jun '04

Has the NZ Internet connectivity been mapped out yet? Maybe I'm not googling right, but I can't find any resource which lists national and international connectivity for New Zealand. -- Juha

Indeed. Peering by US content providers is one of the big changes identified in http://www.nanog.org/mtg-0405/pdf/norton.pdf . Perhaps sadly, one of the possible futures for the US identified by the author in answer to questions about his presentation at the most recent NANOG was the New Zealand model, in which charges aren't made for national traffic. - Donald Neal Donald Neal | Bubble and squeak Technical Specialist | - Boiled mouse.

TelstraClear Inhternational / National Traffic billing
by neil gardner 15 Jun '04

Hi guys - I just spent 5 minutes talking to Telstra in between 45 minutes of working while on hold... The question I asked was: If TelstraClear go ahead with cutting the links to a couple of big national network access points (I was speaking to a non-tech), what will happen to the national / international traffic billing. This person had zero clue but came back ten minutes later and stated she'd been talking to someone that knew exactly what I was talking about. His statement was that "Shortly the International / National traffic distinction will be phased out and there will be only one class of traffic. The cost will be similar to the current International rate. But don't worry since it only matters if you go over your limit" (The lady relayed his comment and that's as close to a direct quote as I can recall) Does this mean that TelstraClear are going to adopt the Telecom Jetstream traffic charging model? Anyone in the know care to correct me if I was given false information by junior Telstra Staff? Or, horribly, was this statement correct? (I specifically wanted to know what would happen to my national / international charging if TelstraClear cut their peering, and it appears they do in fact have a plan to make sure the consumer experiences no confusion over what's National or International traffic) Cheers - Neil G NOTICE: This message contains privileged and confidential information intended only for the use of the addressee named above.

No, it doesn't mean I might as well let the stuff through... -- Juha

Um, no false positives? doesn't that mean you manually inspect all your logs of dropped connections? Doesn't, by extension, that mean you might as well let all the stuff through and check them at the client end? :-) Cheers - N >>> Juha Saarinen <juha(a)saarinen.org> 15/06/2004 3:30:14 p.m. >>> neil gardner wrote: > http://www.cs.niu.edu/~rickert/cf/bad-ehlo.html > > Decent understandable writeup of the "You should send the right info" > and "Don't drop email if you get the wrong info" arguments... ... and having said all that, I admit to dropping some some messages based on HELOs.

Some admins think it's BOFH to do stuff like that, in the mistaken belief that it's RFC-compliant. It's a bit like fundamentalists interpreting various religious scriptures, but if they want to drop legitimate email, their choice I say. -- Juha _______________________________________________ NZNOG mailing list NZNOG(a)list.waikato.ac.nz http://list.waikato.ac.nz/mailman/listinfo/nznog NOTICE: This message contains privileged and confidential information intended only for the use of the addressee named above.

SMTP Servers and Reverse DNS Lookup
by Regan Murphy 15 Jun '04

I was having problems sending mail to an organisation and eventually worked out that the host name and reverse dns entry did not match and therefore mail transfer was refused: ------- 220 mail.xxxbar.co.nz ESMTP NetIQ MailMarshal (v5.5.5.8) Ready ehlo hellmouth.oaxxxsystems.co.nz 554 No SMTP service here ------- As soon as I corrected my server to use the correct host name to match the reverse (vampire.oaxxxsystems.co.nz) then mail was allowed to go through. I would assume this was a recent change by the receiving organisation as I have not had problems sending them emails before. Is this sort of configuration becoming standard for organistions? I would expect that may create problems for smaller organisations sending email directly from their in-house hosted mail server for which they have no control over reverse-dns entries. -- Regards, Regan

Well.. You could get a link to both, but the only real benefit would be splitting the cost between two (probably slightly more expensive this way as a separate circuit is needed for both - generally cheaper to upgrade a 10meg to 100meg than it is to install 2x 10meg eg. one from each telco) However, you would have a shorter data path.. As with two circuits, the data goes direct to both carriers.. With just one circuit, data to clear, goes via telecom.. (provided they keep the peering between them). -----Original Message----- From: jfp [mailto:jfp(a)clearfield.com] Sent: Tuesday, 15 June 2004 12:16 p.m. To: 'Craig Spiers' Subject: RE: [nznog] TelstraClear Inhternational / National Traffic billing > They shouldn't be connected to the internet at all!

The National Library of New Zealand has been given a lot! of money, i expect they will have a good map soon......... http://www.beehive.govt.nz/ViewDocument.cfm?DocumentID=19882 And an older National Business Review article: http://www.nbr.co.nz/home/column_article.asp?id=1978&cid=1&cname=Media Maybe some of it can be spent on peering networks together to help with the flow of _all_ websites ending in .nz to be harvested daily by the NatLib... This task is now part of the National Library Bill and can be thought of being the same as the Legal Deposit legislation.
