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.

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
