Beacuse MFS screwed up but making a MAE-[insert-any-town-with-population-over-500,000] and never marketed it right. MAE-NY could have been HUGE, but there is only 0 providers (maybe 1?) in there now.

has anyone hacked QMail or Sendmail so that it could act as a mail server without actually having accounts on it? The idea that I have is that when a user gets mail (ala SMTP connection coming in), or the user checks mail (ala POP connection coming in), the mail server (Qmail, Sendmail, whatever) could make an ODBC/SQL call to a NT Server running MS-SQL (doesn't really matter, as it is a pure ODBC call). Has anyone done anything like this? Just curious. Thanks in advance. Pointers would be good also.

Network Outages (was: AlterNic antics)
by Steve Carter 15 Jul '97

15 Jul '97

George, My 2 pence worth: Networks do not crash of their own accord. Hardware failures may take a network out, but the highest, by far, culprit for outages is human error. If changes are not made, or closely managed, then networks will stay up.

AlterNic antics
by Peter Giza 15 Jul '97

15 Jul '97

So what is the difference between Alternic's antics "DNS Storm" and: Robert T. Morris, the author of the Internet Worm program, was convicted of a Federal felony in the case. The law involved was 18 USC 1030 (A)(5)(a), the Computer Crime and Abuse Act of 1986. He was found guilty in February of 1990 in US District Court in Syracuse, NY. Granted the "worm" was a lot more serious, but it still interrupted "normal service" (whatever that is). -pete -- --/ Peter E.

We have a modified: sendmail mail.local popd all of which verify accounts against our internal database (same one which handles Radius queries and which the web/ftp server uses to do authentication and transfer limit quotas... in our case, a custom-written database package that keeps local copies of all of the data, and can read it in a single disk seek, so there's no problems if the network to the database server is ill) there's only about a dozen lines of code in each (usually the fastest solution is to have a routine which accesses the database, and then fills in a fake passwd struct as would be returned by getpwent) nice thing is that you can build in things like "allow mail to arrive, but return special failure code when user connects to pop server" to deal with "customer exists but hasn't paid for >45 days", and even more clever... "forward this mail to this other address for 30 days, and then bounce thereafter" only hint to be had is that even though it feels like modifying mail.local should be enough, sendmail ALSO checks to see if the user exists on the system before asking mail.local to do the delivery, so you need to hack both of them. we've investigated making the same hacks to both MMDF and qmail, and these appear to be equally trivial. -matthew kaufman matthew(a)scruz.net

October NANOG meeting
by Susan R. Harris 15 Jul '97

15 Jul '97

Hello everyone - we're pleased to announce that the fall '97 NANOG meeting will be hosted by Genuity and held October 27-28 at the Radisson Resort Scottsdale, near Phoenix. The meeting will run from 9:00 a.m. on Monday, October 27 (with coffee hour at 8:30 a.m.) until 4:00 p.m. Tuesday, October 28. On the Sunday evening before the conference, Avi Freedman, the founder of Net Access, will present a tutorial entitled "Raise your Routing IQ: Design and Debugging Techniques for Intermediate Users" from 7:30 - 9:00 p.m. We also wanted to let you know that as of the October meeting, NANOG will no longer receive any funding from the National Science Foundation. To compensate for the loss of NSF support, we plan to raise the registration fee from $100 to $150. The National Science Foundation has generously provided support for NANOG since the group was founded in February 1994, as part of NSF's support of the NSFNET Backbone Service and the Routing Arbiter project. NSF views NANOG as an important forum for the exchange of network operational information, and commends the ongoing success of the NANOG conferences. Since the U.S. Internet successfully transitioned in 1995 from the NSFNET to a commercial networking infrastructure, however, NSF has focused its networking support on network research and development efforts, rather than operational activities such as NANOG. We wish to thank NSF for its past support, and look forward to NANOG's continued growth and success as a self-sustaining organization. The $50 increase in the registration fee will allow us to cover meeting costs after the withdrawal of NSF funding. We hope that this will not be a hardship to attendees, and look forward to seeing you in Phoenix in October! Web registration will begin August 1; further details will be available soon. --Susan Harris and Bill Norton, Merit
