Configuring cache server with BIND

Bobbychat · 12-22-2003, 03:50 AM

Hi all,
I am new to BIND.I have configured it to work.I would like to make it work as a cache server.The details of my named.conf is shown below.What else is to be configured to make it keep the records in the cache

Here is my named.conf:-

options {
directory "/etc";
pid-file "/var/run/named/named.pid";
forward first;
forwarders {
1.1.1.1;(My ISP' PrimaryDNS server)
2.2.2.2;(ISP' Secondary DNS Server)
};
};

zone "." {
type hint;
file "/etc/db.cache";
};

Any help would be very helpful....

Thanks

That's it, actually. named will automatically cache responses it gets (and in the case, pass on any questions to your ISP if it doesn't have the answer cached). Just point your clients to do DNS lookups from your server.

Thanks Chort.

BTW:Where does it keep the cache data?in the etc/db.cache file?

Thx once again....

It's not written to disk, that's the great part about it: Always in memory.

Hey Chort!!,
Why doesn't my /var/named folder does not have any files?Its empty.What are the files that should be inside Var/Named folder?

Nothing. Your named.conf and "hints" file are both in /etc, and you pid file is in /var/run/named. Since you're not authoritative for any zones, there's nothing else to write to disk.
