You won't find anything. This is false, but I didnt expect any better from you. ISC widely rely on FreeBSD internally, and contribute *lots* of resources to the FreeBSD project including hosting one half of ftp.freebsd.org and employing several FreeBSD developers. >> e.g. NSD >> (ports/dns/nsd) is a much faster and more scalable DNS server than BIND >> (because it is better optimized for the smaller set of features it >> supports). >> > > When you make remarks like that it's no wonder ISC is in the business > of slamming FreeBSD.

NSD *is* faster, it *is* more scalable, it *does* support fewer features than BIND, and it *is* more optimized for those features (e.g. it tries to precompute DNS responses, which it can do because it doesn't support dynamic updates, etc). The ISC devels acknowledge this. BIND has architectural constraints from being a more complete DNS server solution. > If nsd is so much better than yank bind out of the base FreeBSD and > replace it with nsd.

Somehow you got out of my killfile though, guess I'll fix that. Kris
