fyi ------- Forwarded Message To: bind-announce(a)isc.org Subject: BIND 8.2.2 (T3B; RC0) is available for general testing Date: Tue, 24 Aug 1999 00:01:59 -0700 From: Paul A Vixie <vixie(a)bb.rc.vix.com> Confidence: moderate. This is running on part of F.ROOT-SERVERS.NET and on all of our local production servers. The only reasons it's not a full release candidate are that IXFR is still disabled and we're still tinkering with the NT support. Highlights vs. BIND 8.2.1: Preliminary support for Windows/NT (thanks to BayNetworks). More fixes, especially to DNSSEC, TSIG, IXFR, and selective forwarding. More portability improvements and lint removal (A/UX 3.1.1, SCO 5.0). Better NOTIFY behaviour, especially with large update volume. Better UPDATE handling, including SRV RR support and RFC compliance. Fix for "ndc reload ZONENAME" (specific zone reload) problems. Fix for round robin when multiple CNAMEs are in use. New "min-roots" (MINROOTS) and "serial-queries" (MAXQSERIAL) options. Log files are no longer auto-rotated every time the server starts up. New "ndc reconfig" command only finds new/deleted zones, no stat()ing. New global options for "update-source" and "also-notify". $GENERATE now supports more record types, and options. the distribution files are: ftp://ftp.isc.org/isc/bind/src/testing/t3b/bind-src.tar.gz ftp://ftp.isc.org/isc/bind/src/testing/t3b/bind-doc.tar.gz ftp://ftp.isc.org/isc/bind/src/testing/t3b/bind-contrib.tar.gz the pgp signature files are: ftp://ftp.isc.org/isc/bind/src/testing/t3b/bind-src.tar.gz.asc ftp://ftp.isc.org/isc/bind/src/testing/t3b/bind-doc.tar.gz.asc ftp://ftp.isc.org/isc/bind/src/testing/t3b/bind-contrib.tar.gz.asc the md5 checksums are: 0abf1631852beb1d989b4d41759641bf bind-contrib.tar.gz d82f381d0904ee236b5262abb9ac1484 bind-contrib.tar.gz.asc 4e51a75f0dd42327daa6f922b4fd4fab bind-doc.tar.gz c417a461f329abce517ade68c735f154 bind-doc.tar.gz.asc feb88267cd52196fcf0097b2ef6f04c1 bind-src.tar.gz 38446afd2df7b62af88facf35191ca03 bind-src.tar.gz.asc top of CHANGES says: --- 8.2.2-T3B released --- 783.

Having to have a written code of ethics is usually a very sure sign that there are problems in this respect. Every time i hear about anything like that i'm reminded of the Moral Code of Bulider of Communism (yes, there was a poster with that text in virtually every classroom in the ussr). That one was a lot more comprehensive, too. Well, the early Internet types have unwritten ethics - and it is a hell lot different from the corporate ethics of the Professional Engineers (tm). Clashes between these two often provide spectacular fireworks :) --vadim

Re: Training the next generation:
by Dana Hudes 24 Aug '99

Darin, thanks for the feedback. All the bridging issues you mention are covered in Tannenbaum. Packet captures for examples is a good thought. These students are already familiar with the spanning tree algorithm from a previous course, they just don't know that it is good for bridging. I don't have complete details by section but the book details are at http://www.phptr.com/ptrbooks/ptr_0133499456.html for Tannenbaum and http://www.phptr.com/ptrbooks/esm_0130117021.html for the project book by Grodzinsky IP addressing is covered in Tannenbaum, as are routing algorithms. Obviously Tannenbaum doesn't cover OSPF to the same depth as Comer or John Moy's OSPF book. The URL for my syllabus for CSCI 415 Telecomputing is in my original post. A syllabus for a TCP/IP course is posted by Comer at http://www.cs.purdue.edu/~comer/courses.html . What I'm most concerned for is the special topics course. There is no time for bridging and other L1/L2 stuff (or ATM wherever layer you stick it).

snmpstat monitor ver. 1.2.e - see http://noc.bn.ru/~alex/MON
by Alex P. Rudnev 24 Aug '99

24 Aug '99

I completed, as promised, the work of collecting distribution pack for the snmpstat monitor (version 1.2.e, where 'e' means _english menu available_). The system was tested for the FreeBSD and Solarys 2.6, but I believe it can work fine on any Unix where CMU SNMP library can be translated. This pack include: - the russion and english dicumentation; - the installation pack (tested for the fixed /p/stat and user: monitor group: monitor configs but theoretically allowing to use any location and user), including snmpstatd daemon, WWW interface to the monitoring system, LINKS data base and WWW interface for it, and (in addition) modems_poll monitor (withouth any WARRANTIES and docs). This (1.2) is SHAREWARE software - we ask you to contact us in case this appear to be usefull for your market or provision work, if you are the commercial company. I can't promise the next (with the object priorities, snmp polling of the modems, service monitoring etc) version should be just as free as this one, but it should not bee 100% commercial anyway.

I didn't forget. My question was a bit of a Rorschach test. How would people perceive and compare the relative severity of two very small events. You are correct the number of GPS receivers used in timing applications, especially feeding the Internet, is a very small number compared to all GPS receivers. The number of stratum 1 clocks on the Internet is even smaller number. Most are maintained by people with a near obession for keeping track of the correct time. But I'm a psychologist. I'm interested why so many consumers didn't head the warnings, and take advantage of the the free upgrade offers from manufactures to fix their GPS units before the rollover. I mentioned I didn't find information on Pioneer's web site. Actually I just didn't go back far enough. It turns out Pioneer asked consumers a year ago to bring their units to be repaired. Another person told me about a company which needed to shutdown their operations for a couple of days because their consultant told them the wrong date for the rollover, so they weren't ready when it occured. Although I'm not sure waiting until the last week, even if you consultant did give you the wrong date, to update your equipment was very smart. And the Darwin factor is always an issue. Even after all the publicity, at least one boater who set sail without checking his GPS, needed to be rescued. When asked by reporters in Japan why they didn't upgrade their GPS receivers when the manufactures told them the units wouldn't work, consumers said "I didn't think it would affect my unit." No, I don't think japanese consumers are that different from any other consumers in the world. How does this affect network operators? Could we learn something from how consumers reacted? Do you set up a seperate contact number for consumers who waited too long, so they don't clogged up the queue for consumers with other problems? If you think its hard to reach a "cluefull" person on a normal day, will it be worse? -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

| What's wrong about a good thread lasting long ? I wish Karl Denninger (famous Internet Engineer) was here to inform us that the governments mentioned in this thread are unlawfully supporting a monopoly, and imposing a barrier to entry against perfectly intelligent, competent people, and that the correct remedy now is to sue them, and that Karl's own lawyers are already preparing a case.

Unfortunately being a teacher is a completely different profession which requires completely different talents. A lot of very good engineers are poor teachers. Having tried to teach professionally i know that it is much harder than it seems. --vadim PS Actually, i do not see shortage of clueful network engineers. What i see is complete lack of clueful managers. Engineers are often left without any useful managerial support, and all too often are simply screwed up by the bad management. That's why i think the fact that good engineers are getting more expensive is positive. When management if forced to pay through the nose for the professional expertise, they more likely feel compelled to follow the offered advice. It is quite possible to run a large backbone with two-three top-notch engineers - providing they can pick their assistants and don't have to spend most of their time dealing with bureaucratic idiocy.

The facts that somebody is being professional, educated and ethical does not guarantee that he has any idea of what he is doing. The catch is that a clueless person is generally unware that he's clueless, so he can be quite eithcal and professional in what he thinks he is doing.

Off topic: Numbers of Internet engineers/operators
by Pete Kruckenberg 23 Aug '99

23 Aug '99

This is probably off-topic for the list, so I apologize. I'm trying to find some numbers (surveys, etc) that show the numbers of network engineers and operators (ie operations people, network engineers, network architects, possibly systems engineers, sysadmins, etc--for both Internet and/or intranet networks) that are working on the Internet today and maybe projections for the future. Numbers on personnel shortages would be good, too. Thanks for any references you can give me. Pete.

I made a post recently and was informed that it was off topic and that I should consult "newbie" mailing lists for questions of this type. I have a desire to develop some "clue" but unfortunantly I was not given any direction as to where to go to subscribe to these mailing lists. If someone would please point me in the direction of these mailing lists I would appreciate it. Off list responses are fine lbirch(a)wans.net . I realize this is not on-topic so please no flame.
