Re: Caching nameserver question - I need a spot here . . .
# [EMAIL PROTECTED] / 2003-01-27 17:15:29 -0500: Hey all. I'm finally getting around to setting up a caching dns server. Pretty confusing from my angle. Here's what I have so far: named enaabled in /etc/rc.conf cd to /etc/namedb and run sh make-localhost and the following in /etc/namedb/named.conf: options { directory /etc/namedb; forward first; forwarders { 151.203.0.84; 151.202.0.84; }; listen-on { 10.8.20.5; }; version surely you must be joking query-source address * port 53; }; zone . { type hint; file named.root; }; zone 0.0.127.IN-ADDR.ARPA { type master; file localhost.rev; }; are you setting up a cache, or an authoritative server? IOW, do you want Bind to resolve names for clients (they'll will have it in /etc/resolv.conf and equivalents), or do you want it to publish names? You are doing both, but if you want to have this Bind resolving names for clients (external cache), being authoritative for 0.0.127.in-addr.arpa doesn't IMO make sense. -- If you cc me or remove the list(s) completely I'll most likely ignore your message.see http://www.eyrie.org./~eagle/faqs/questions.html To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message

I want just a caching nameserver. If I understand correctly, you are suggesting I remove the 0.0.127.IN-ADDR.ARPA zone. So I should only have the hint zone, right? Thanks for your comments, Roman.

Lots of luck! I probably should have mentioned this, but that page is exactly how I got this far in the first place. Section 10.9.7 (Caching Name Server) says only this: A caching name server is a name server that is not authoritative for any zones. It simply asks queries of its own, and remembers them for later use. To set one up, just configure the name server as usual, omitting any inclusions of zones. So I guess my main question is do the following default zones violate that statement, or are they exceptions? zone . { type hint; file named.root; }; zone 0.0.127.IN-ADDR.ARPA { type master; file localhost.rev; }; And, what about the Options section? Am I understanding the use of the forwarders, forward first, and listen-on directives correctly? I have put some effort into this, and the configuration above is the result of that effort, so I'm not asking anyone to do it for me. However, I know there have been more than a few people who have started out intending only to set up a basic internal service of some kind, only to have their mistakes cause trouble externally. I've been there myself, and I'm just trying this once to avoid that one step commonly referred to as 'making an ass of yourself.' Particularly since screwing with the ISPs dns service availability isn't exactly smiled upon.

I have forward only rather than forward first. So far my DNS providers haven't failed me! 2/. I run named as a non-privileged user. I haven't configured a complete sandbox (see http://www.au.freebsd.org/doc/en_US.ISO8859-1/books/handbook/dns.html#NAMED-SANDBOX for that), but just did the following: mkdir /etc/namedb/s chown bind:bind /etc/namedb/s chmod 750 /etc/namedb/s Add the following to the options in named.conf dump-file s/named_dump.db; and named_flags=-u bind -g bind to /etc/rc.conf. 3/. I don't have the version and query-source lines. I don't believe they'll break anything for you. 4/. I have set up an authorative lane.family domain for my home network 5/. You may want to add 127.0.0.1 to your listen-on option. I can't see anything in your setup as is that will wreak havoc on the internet, but I am not an expert. I would at least run it as bind:bind rather than root as it is trivial to set up. A complete sandbox is better, and of course a jail would be even better, but they are both more work.
