Upon redoing my paths file recently, I noticed that pathalias now considers
the fastest trip from here to uunet to be
telly!utzoo!utgpu!utai!watmath!uunet
rather than what it used to be, telly!attcan!uunet
This brought on a couple of curiosities:
1) What's changed in local connectivity to bring this about? Does watmath
really talk to uunet every 1/2 hour?
2) I thought UofT also talks to uunet. If the waterloo connection is so
good, why bother?
3) Has anyone else seen this change?
4) Can anyone confirm what I've heard as rumour, that Telebit
LD links for news feeds are actually cheaper than X.25?

The one via mnetor worked fine (although it didn't go out of Toronto until midnight (NOTE: I'm definitely NOT complaining) but it got turned around immediately at uunet & was back here within 30 minutes). The one via watmath translated into utcsri!utai!watmath!uunet!... but it bounced off utgpu, yes gpu! It seems that watmath's internet path actually goes via utgpu (though why I don't know!) but it mangled the bounce path to such an extent that gpu couldn't make sense of it and I got some nice mail from Postmaster@gpu. Needless to say, I re-ran pathalias with -dwatmath!uunet. Everything is now fine. >This brought on a couple of curiosities: > >1) What's changed in local connectivity to bring this about?

My understanding is that UofT does not want to be the local mail hub any more than they already are. Note that the waterloo internet connection PHYSICALLY (if not logically, see above) goes through UofT. Moreover mail from Toronto will follow some UofT path to Waterloo, then back to UofT to head on to uunet. Not very efficient. I thought Rayan was going to control the costs so Waterloo would not look like the path of choice from Toronto. If anyone is going to advertise an internet connection, it would make more sense for it to be UofT, but I gather the politics of the situation prevent it. >4) Can anyone confirm what I've heard as rumour, that Telebit > LD links for news feeds are actually cheaper than X.25?

This does seem rather strange indeed. The path is definitly not what
it should be. As far as I can tell watmath calls uunet using the UofT
Internet connection. The utgpu <-> watmath link is over ONET. The message
travels to UofT, thence to waterloo over ONET, back over ONET to UofT, and then
down to uunet. The shortest path would be telly!utgpu!uunet but the appropriate
path should be telly!attcan!uunet -- utai is no closer to the Internet than
any other host at UofT.
My concern, however, lies elsewhere. I'm sure the folks at Waterloo didn't
intend to advertise the NSFnet connection at UofT as the default path down
to uunet. AT&T Canada have graciously offered to handle email traffic to
uunet. It is not appropriate to use the NSFnet link at UofT for this.

I strongly suggest everyone edit the watmath UUCP map entry and change all DEDICATED costs to HOURLY, except for uunet which may be HOURLY/2, and ubc-cs which should be DEMAND. This should put the routes back to normal (after you rerun pathalias). I'll bring this up with Onet sites, to be careful of such things in the future. No local connectivity has changed, only the advertised costs from watmath.

Back in December, I was getting bounces from the following path: lsuc!utai!watmath!alberta!oha!tony oha was bouncing back "can't send to .tony" (I *think*). Didn't get any response from watmath by posting/mailing about it at the time other than from Rayan saying "it's watmath" twice. (quite literally, those were the only two words in his mail messages). I had done some testing and it appeared that watmath was doing it, alberta's log appeared to show that it arrived with the mangulation in the uux command line. There was some discussion in comp.mail.uucp or comp.sendmail or something about a bug in sendmail header handling with "From:" lines. I misremember the details.... I'm sending a new test right now to see if it still happens and I'll send you the header if it happens again. -- Chris Lewis, Markham, Ontario, Canada {uunet!attcan,utgpu,yunexus,utzoo}!lsuc!ecicrl!clewis Ferret Mailing list: ...!lsuc!gate!eci386!ferret-request (or lsuc!gate!eci386!clewis or lsuc!clewis)
