BIND: where can I get the db.cache file?

[discoverer]

Hello All,

Can you help me?
Thanks in advance!

PS.
As the training book says:
After running 'hosts_to_named -f param' to create the DNS DB files, another file named 'db.cache' need to be created to resolve the addresses of the root domain servers.
The original content can be get from internic's web site.

But I didn't find it via www.internic.net and ftp.internic.net.

You should be able to get the list of root servers from the following URL:

ftp://rs.internic.net/domain

In particular, I think you were looking for the named.cache file.

Hope this helps.

You can get from where santosh says.
or cut and paste this

; Initial cache data for root domain servers.
;
; <<>> DiG 2.0 <<>> @ns.internic.net . ns Last update 2/1/96

; Prep the cache (hotwire the addresses). Order does not matter.

F.ROOT-SERVERS.NET. 518400 A 192.5.5.241

you can give it a name what ever you want in /etc/named.conf(if BIND is > 8.x or 9.x) /etc/named.boot(if bind is 4.x) configuration file.

Hi,

Take a look at the thread below,

Thanks for everybody's help!

BTW, I happened to find a file named /usr/examples/bind/db.cache.arpa in HPUX11.0,
yet 10.20 hasn't.
But it is of no much use.
