Responses to Letter from ING
by David Farrar 04 Sep '01

04 Sep '01

I'm inquiring if any ISP or like body knows of any business who responded to ING's letter and either changed their mind or now wishes they changed their mind? TVNZ are doing an article on the letter and would like to be able to interview someone who was taken in by it or at the minimum who was going to take it up until they sought advice. Also any indications from ISPs as to how many calls they have recived about the letter would be useful. If you know of anyone can you pass on their contact details to me or alternatively get them to contact me by e-mail or on 04 471 9353, preferably by midday tomorrow.

Secondary MXes (that can only queue and attempt onward delivery) are about "concentration of pain"; instead of the pain being spread across all the mail servers trying to deliver to the one that is down, it's concentrated in the secondary MX(es). This concentration of pain was more useful in the days when there were quite a few slow, not always up, links trying to deliver mail (especially dial-on-demand type links; uucp tended to be smarthosted once things got to a point that it mattered). Now that the common mode of mail delivery is basically two tier (clients deliver to their ISP's smart host, that smarthost is always connected and "easily" able to retry the mail often enough") there's less advantage in concentrating the pain. Especially weighed against some of the disadvantages you mention (eg, don't get "trouble sending" bounces early if sender end has low timeouts on those, but secondary MX doesn't). Except perhaps when the pain lasts a long time (hours, if not days), and causes a fair amount of trouble to a lot of people/mail servers. Like Xtra at the moment from what I've seen on nznog. BTW, has anyone considered that the reason that no one from Xtra has spoken up is that their outgoing mail is having trouble as well as their incoming mail? :-) Ewen --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

There are also other tricks you can run depending on your >mail software and network setup. Not to mention that mail servers around the country trying to connect to xtra's all the time wastes other peoples bandwidth. With a backup MX the mail queuing and retrying would be occuring between their backup and primary MX which in all likelyhood would be internal traffic (perhaps even on the same switched ethernet) rather than over national links. Dequeuing when the problem was resolved would be faster and more efficient than waiting for various random servers around the country to retry. >The anoying bit is that Xtra has not acknowledged this in public at all, >we are getting our customers blaming us for delays in email getting to >Xtra addresses. Well actually, they have acknowledged the problem on their website, (I was surprised, I was expecting the standard "There are no knon problems with the Xtra network") so short of making a public annoucement on TV and radio I don't see what else they could do to raise awareness to the average user :) Regards, Simon --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog

Discussion will focus on Internet operational and technical issues. 2. Discussion related to meetings of network service providers is appropriate. 3.

RE: Wireless LAN equipment
by Greg Clare 02 Sep '01

Just another thought for ya... If it is a single story house and you can get under the house, then what I did was simply drill a small hole through the chipboard floor (just big enough for the Cat5 cable to get through), at the very edge of the carpet, right next to the skirting board. A small hole in the floor at the edge of the carpet line is invisible to anyone making a visual inspection (unless you get the carpet caught in the electric drill and rip a huge chunk of wool out... try to avoid this!). Then, if you don't want to screw Cat-5 outlets to your skirting board, just crimp the RJ45 plugs directly onto the leads that come up from under the floor so you can plug the leads straight into your RJ45 device. When you move, just cut the plug off one end of each lead and pull them back through, the little holes are left hidden by the carpet. PS: Going under the house also saves getting your lungs full of glass fibre.

[addresses that don't resolve, etc, can kill whole list] Not to rain on anyone's parade, but most mailing list software injects messages in queue mode (to avoid an explosion of MTA processes trying to send the messages out immediately (in the background)). This then relies on the MTA queue processing to shift the messages out. Has anyone checked how often the queue is run on the relevant server? If it's every 30 minutes it'd pretty much exactly explain the times reported. If it's every 15 minutes (a common default with sendmail), then 15-minutes plus isn't that unlikely to happen given the right circumstances. For a mailing list of a few hundred addresses, it should be a walk in the park for most MTAs, sendmail included.

Wireless LAN equipment

Hi all In the interests of keeping my soon-to-be-landlord happy, I'm looking at building a wireless LAN rather than making holes in the 13-month-old house I'm about to move into. Can anyone recommend any particular equipment, suppliers, sources of information? It'll only be a small network to start with - five systems, though it'll grow; I have a nasty habit of accumulating junk :P Many thanks Richard -- Richard Stevenson, Systems Specialist, Xtra Limited Phone: +64 9 355 5231 Mobile: +64 25 290 3101 Pager: +64 26 100 155 "Visual $ANYTHING" just screams out "100% suckage or your money back". -- Tanuki the Raccoon-dog, in the Monastery --------- To unsubscribe from nznog, send email to majordomo(a)list.waikato.ac.nz where the body of your message reads: unsubscribe nznog
