NZNOG 2005 in Hamilton
by Donald Neal 15 Jun '04

15 Jun '04

Planning is now under way for the next NZ Network Operators' Group conference. This is to be hosted by the WAND group (Thanks again, guys!) at The University of Waikato's main campus in Hamilton in the first week of February 2005. If you have an opinion on the form this should take, please speak up now. If not, you're likely to end up with something bearing a strong resemblance to this year's gathering, with tutorials on Wednesday and a stream of presentations on Thursday and Friday. (That's 2-4 February.) Don't rush to volunteer to present just yet - we should have a proper Call for Presenters out around the end of this month - but now is the time for people who are likely to attend to suggest topics they'd like to know more about, people they'd like to hear from, or changes to the way things have been done in the past. Please post suggestions either to me or to the list as seems appropriate. I'll try to provide a digest of responses by next Friday, 25 June. - Donald Neal Donald Neal | Bubble and squeak Technical Specialist | - Boiled mouse.

Re: Dynamic address space in SORBS causes mail rejection

All true. On Jan 30 The Telstra Abuse Desk wrote to SORBS about the block being labelled as "dynamic" and asked for "a copy of the headers of the spam". SORBS replied, explaining that the DUHL list identified their IP's DHCP status, not that any spam had been sent. Telstra Abuse Desk didn't respond to that reply. On March 11 Mark Seward wrote in again from Telstra, asking for the block status to be changed: SORBS replied, explaining that for security reasons such a request would need to come from the designated APNIC PoC for the IP block (which currently would be netobjs(a)clear.net.nz) However that reply got an auto-response saying that Mark Seward was no longer with Telstra, and mail should now go to Peter Ambrose and/or Sid Jones, so SORBS dutifully forwarded the previous correspondence to those two people, hoping they'd get the appropriate person to write in to authorise the change. But nothing further was heard until April 7 when Jason, as "isp.duty(a)team.telstraclear.co.nz" wrote in asking how to get the block's status changed, and he was sent a similar answer to that which had gone to Mark Seward, Peter Ambrose, and Sid Jones: but still nothing was heard from the designated PoC. | I've asked around about this and the best suggestions are "you're an | ISP customer, you should be smarthosting through an ISP mail server." | Problems with this include the fact that we no longer have any control | over retry/routing/any of the niceties of controlling your own outbound | SMTP; the fact that clear.net.nz mailservers are currently being eaten | by Zafi and mail delivery will probably slow down; and the fact that | we "just plain shouldn't have to."

Dynamic address space in SORBS causes mail rejection
by Craig Box 15 Jun '04

15 Jun '04

Hi everyone. While we're on the subject of mail rejections, I look after a couple of sites on a TelstraClear Tempest connections, both with IP addresses on 203.97.48.0/21. Unfortunately, spam DNS blacklist SORBS (http://www.dnsbl.au.sorbs.net/) list them as being on Dynamic IP space: 203.97.48.x found in Dynamic IP Space (Cable, DSL & Dial Ups) Address or Block: 203.97.48.0 / 21 Information: Dynamic IP address, use your ISPs mail server ...and as such a number of sites (a number growing by about one a day, just the ones I get told about) are blocking mail based on the SORBS listing. Some months ago I got in touch with TC's faults desk and they claim to have emailled off to SORBS to have this reclassified. Nothing changed, so I got in touch with our local tech contact at TC; he said he'd fire it off to the ISP guys but I've not heard back from him either. I've asked around about this and the best suggestions are "you're an ISP customer, you should be smarthosting through an ISP mail server." Problems with this include the fact that we no longer have any control over retry/routing/any of the niceties of controlling your own outbound SMTP; the fact that clear.net.nz mailservers are currently being eaten by Zafi and mail delivery will probably slow down; and the fact that we "just plain shouldn't have to." We have a hosted mail server of our own that we could use as a smarthost, however it will be a significant increase in load on this machine where we have a perfectly good mail server sitting at the clients site. I agree completely about customers not running mail service on dial-up lines, but a Tempest connection with a static IP address is a business service, not a 56k modem with an infected Windows box behind it. I'm not sure where to go from here. It's possible that if I ask TC to set the PTR for each affected customer to smtp.$CLIENT and then manually request that it's removed from SORBS, it may be done. Their FAQ (http://www.dnsbl.au.sorbs.net/DUL-FAQ.html) suggests I'm more likely to be asked to have my ISP ask. I'd like to see TC deal to this, perhaps by putting more information in the WHOIS db about what space is static and what is dynamic, and possibly changing PTR records appropriately. According to the DNSBL faq, the contact listed in the RIR can have it changed - it would be really nice if this problem could go away. If there are any other suggestions that anyone has about how to deal with this problem, please let me know.

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

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.
