(silly?) question about dns server cache

onearm · 2008-04-25 08:40:02

I installed on an old pentium3 pc the bind server, just for fun and for testing if a local dns server could made an huge difference in resolving addresses. It's configured as a mirror of my ISP's dns server and thus far all is good and faster.
Now I have a probably silly question but why there is no way to save to file the server cache to be available after a reboot (I really don't need nor want to keep the pc on all the day and night)? Isn't a waste of time and bandwith contacting again the isp's dns server for queries already resolved just yesterday?

I'm aware of the risks in phishing and stale cache, I just want to test it.
And anyway, if this is not possible with bind or any other dns server, is there a software that can save the dns cache on disk to be available even after a reboot? Maybe with a weekly flush and syncing with the isp's server?

Thank you

I think that maybe pdnsd would be a better decision in your situation. pdnsd is a dns proxy server with persistent caching. If you're still interrested you could read more at:

http://wiki.archlinux.org/index.php/Pdnsd

and get PKGBUILD from:

I'm sorry to pointing you like that but I've never used it—I only know about existence of such program.

Hope this helps!

Didn't know of the existence of pdnsd, looks what I was looking for. Thanks for pointing it to me.
