ICMP message types
by Rob Thomas 24 Jul '02

24 Jul '02

Hi, all. I am opposed to blocking all ICMP, for many good reasons. I do limit the ICMP types and codes I allow, however, and have put together a list that might help others as well: http://www.cymru.com/Documents/icmp-messages.html Feedback is welcome and encouraged. Be the first in your ASN to make it to the Credits section. :) I hope this helps! Simon, thanks for the suggestion to post this link to the list. Thanks, Rob. -- Rob Thomas http://www.cymru.com ASSERT(coffee != empty); - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

You should simply see a return to TCP slow start. TCP congestion control is not very sophisticated, but it does sort of work. And it works end to end. The cause of any packet loss in the middle isn't known to it. - Donald Neal ------------------------------------------------------------------------------ "This communication, including any attachments, is confidential.

NZNOG 2002 and Beyond
by Donald Neal 24 Jul '02

24 Jul '02

Counting heads during NZNOG papers last week showed a steady attendance of somewhere between 45 and 50. (Tony McGregor's paper first thing on Friday morning had an audience of only 36 when it began, but 48 by the time it finished. I suspect that to reflect time of day rather than content or presentation.) That level of attendance, and feedback to various organisers, suggests to me that holding a face to face gathering was a worthwhile exercise. My thanks to all those who contributed, and particularly to Dean Pemberton. Now, if that one was worthwhile, how about doing it again? We have already two offers for future NZNOG gatherings. 1/ UniForum NZ Roger De Salis has volunteered to act as convenor for next year's UniForum NZ conference. In general terms, his intention is to stage a conference similar in structure to this year's, though with Linux content much more focussed toward a business audience, and in general a stronger programme. NZNOG would be welcome to participate on more or less the same basis as this year, though presumably making up a smaller proportion of a larger conference. This would probably be at around the same time of year and probably in Auckland. 2/ The University of Waikato The University of Waikato have offered to host a NZNOG gathering, to be held at their main campus in Hamilton. This would be a stand-alone event, with the university providing administrative staff time for registrations and the like. No decision has been made as to when this would be. If held outside university terms, e.g. in February, accommodation on campus would be available at a cost of approximately $35 per night. There would be a cost for the venue, but this would be well below the rate a hotel would charge. The Hamilton option is likely to have a significantly lower cost. It is possible that a university setting would discourage sponsors, who provided a good number of overseas speakers this year. On the other hand, the likely venue photographs well and we haven't asked them yet. I'd be interested in feedback, quite possibly including issues not considered in this posting. If anyone else has an alternative venue/organisation suggestion, or believes we can support more than one organised gathering a year, let's hear it. - Donald Neal ------------------------------------------------------------------------------ "This communication, including any attachments, is confidential.

Lost at Uniforum :/
by Mark Foster 15 Jul '02

15 Jul '02

Ive misplaced my Targus carryback (designed to carry a notebook computer) during the Uniforum conference. If anyone who was at the conference has picked up or remembers seeing a Black bag around the size of a briefcase - probably in or around the Amy Johnson room (where registrations were run from) id appreciate it if they would let me know. Reward Offered :) Mark. (Feeling somewhat sheepish) - To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

Election night results site peering
by Ewen McNeill 15 Jul '02

15 Jul '02

A client of mine (Catalyst IT) will be hosting the website with the "on the night" election results. The website is a set of static pages (which are updated regularly in a push from the central computer collating the results as they come in; Catalyst IT are also operating this computer at another facility). The website will be hosted at one (or possibly two) addresses out of the Catalyst IT 203.96.153.224/27 CIDR address range (allocated out of a Paradise block). This address range is advertised into WIX (WIX router is 202.7.0.72). They have a 100Mbps connection into Citylink so local bandwidth should be adequate. However for both efficiency and redundancy they are keen to take as much advantage of the peering on WIX as possible. Can I have an indication from the ISPs as to: - how many are accepting /27 routes from WIX? (I've heard some are not accepting routes smaller than /24, or even larger) - for those that do not routinely accept a /27 advertisement on WIX, whether they'd be prepared to accept that /27 advertisement around the election night period (or put in a temporary static route) - how many are advertising their dialup, adsl, cable, etc blocks into WIX (so that the return path is also peered) Comments from anyone that peers at APE (and would accept a /27 route), but doesn't have any peering/connection to Citylink/WIX would also be appreciated. At present the cheapest price for transit to APE (from Wellington) is probably outside the budget remaining, but the issue is still being considered. (Of course if someone wants to offer cheap transit to APE.... :-) ) Messages here (nznog) or directly to me (ewen(a)naos.co.nz or ewen(a)catalyst.net.nz) would be appreciated.
