In my DNS server's named.conf I see rate-limit { responses-per-second 5; window 5; }; What does this actually mean? And can it cause DNS clients problems? Is this too tight a configuration?

Is it possible to recover a deleted named.conf if named still running?

If, for example, you spend some time working on a named.conf, and then by mistake clear it and save it (thanks to vi), is there a saved copy of the named.conf in the running instance that I could grab?

How to allow bind to cache lookup queries

I am using bind-9.3.6-4 in my CentOS 5. How can I allow bind to cache lookup queries so that if there are similar queries it should check from my cache instead doing a lookup from the DNS servers mentioned in the "forwarders"?
