Anyway I pooked around a bit, looked at some configs a friend provided me with and read a bit more about BIND, did some config cleaning up. And its working now unfortunatly I cannot point to where exactly my error was (note to self do more sleeping). Sendmail is functioning properly :) My machines, except one now produce the output that you said they should (and descriped above). I believe the error with that one machine is rooted in nslookup and not DNS. Interestingly there are 2 nslookup programms in the MAN pages. One in section 1 and one in section 8. http://www.freebsd.org/cgi/man.cgi?query=nslookup&sektion=1&apropos=0&manpath=FreeBSD+5.3-RELEASE+and+Ports http://www.freebsd.org/cgi/man.cgi?query=nslookup&sektion=8&apropos=0&manpath=FreeBSD+5.3-RELEASE+and+Ports All my machines are using the one under section 8. (I think you can tell them apart by looking if they have "help" implemented) Only the one machine that is not producing the right output uses the one from section 1. Anybody nows why this is the way it is, meaning why there are 2 nslookups and by which way you can tell a machine to use one or the other ? (seems pretty strange to me) Thank you Hexren [-- Attachment #2 --] // $FreeBSD: src/etc/namedb/named.conf,v 1.14 2003/02/07 20:58:38 keramida Exp $ // // Refer to the named.conf(5) and named(8) man pages for details.
