Dents -- Bind alternative?
by Pete Kruckenberg 30 Nov '98

30 Nov '98

Just saw an announcement for Dents ( http://www.dents.org/ ) on comp.os.linux.announce. This is supposedly a (future) replacement for BIND, as a DNS server. It has some cool ideas (dynamic zones, open storage interface, control interface, etc), but it looks like it's a work in progress. Has anyone looked at this? It seems like it could (theoretically) address several of the DNS issues that have been discussed here and on inet-access lately. I'm not quite sure I understand why these features weren't just contributed to BIND, but maybe it is time for a fresh start... Pete. P.S. Looks like one of the participants works for Mindspring, but there doesn't appear to be any association between this project and Mindspring. ---------- Forwarded message ---------- From: Todd Graham Lewis <tlewis(a)mindspring.net> Newsgroups: comp.os.linux.announce Subject: Dents v0.0.1 - a DNS server Date: Sat, 28 Nov 1998 12:59:06 GMT ANNOUNCEMENT ============ We announce the first public release of Dents, an implementation of the Domain Name Service, as defined in RFC 1035 and others. Dents was designed and implemented by Johannes Erdfelt (jerdfelt(a)sventech.com) and Todd Lewis (tlewis(a)mindspring.com) with Johannes doing most of the real work. We release it under the terms of the GNU General Public License, Version 2, with the proviso that one cannot upgrade to future versions of the GPL without the permission of Johannes Erdfelt and Todd Lewis.

flow export stuff

I asked this a while ago. I asked if anyone knew of any good cisco netflow flow collection and analyzation tools. I played with cflowd, and while archaic, it did work. So, todays question is, is there anything new/gooder/faster that anyone knows about? -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- Atheism is a non-prophet organization.

The Collector is free. The Analyzer goes for $3000. You should run it on an Ultra 1 or better with 256MB RAM and lots of disk. The analysis is quite impressive. Version 2 is much improved over version 1. I haven't run it on a serious box yet (I've been cheating with a dual Sparc 20 w 128 MB RAM! :), but from what I've seen, it is great.

NetFlow Collector and Analyzer from Cisco. They are expensive and require a ton of horsepower on the Analyzer, but they run great.

NON-OPERATIONAL: A note of thanks to ANS
by John M. Brown 29 Nov '98

29 Nov '98

I just wanted to say thanks to the NOC staff at ANS. Since we have been adding several new customer routes to our BGP announcements, they have been wonderful in responding to our questions, and our help. And we are not even a customer of ANS. How does this tie in with operational issues, you might ask? Well, if all NOC's would respond in the manner we have seen from ANS, then life would be easier. Saying THANKS is also a plus since it recognizes people that do good things. Its people that run the Net. And on this list there are sometimes way to many people bitching about something, including me. So I felt it was operationally important to say thanks. Not all of you may agree, and we don't need a thread on this. jmbrown(a)ihighway.net

Democratic forums are open, transparent, accountable, feature regular elections, laws, constitutions and so on. There are no such institutions on the net. There are technically capable but otherwise unsophisticated lads running around pretending they are the law. They aren't.

In a civil forum I have drawn into question the activities of persons acting in what I believe to be unethical and unscrupulous manners. I have attacked no-one and interfered with no person's civil liberties, rights and/or freedoms. Whereas Mr. Vixie regularly trades in the violation of these rights. With nothing more to back him up but technical know-how and a gang of fellow geekthugs. A very unfortunate situation I suspect time will alter to a conclusion more in line with our traditons or democracy than with Vixie et al's propensity to totalitarian despotism.

The Cidr Report
by Tony Bates 27 Nov '98

27 Nov '98

This is an auto-generated mail on Fri Nov 27 12:00:00 PST 1998 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.
