CentOS - Jan 2006 - Bind cache - hobbyist's silly question

I'm running the Bind nameserver on CentOS 4.2. Can anyone tell me where
the cached lookups are stored and whether there is a way to view them?

Kill -2 of named will cause it to dump the cache.  Depends on whether it 
is running in a chrooted directory or non.  Try 
/var/named/chroot/var/named then you should find something like dump.db 
if my memory serves me correctly.

I believe that the cache is in memory only.  You lose it when you 
restart named.

If you have RNDC configured (can't remember if it is by default) then it 
will output the named cache to a local file.

$ rndc dumbdb

That will create a file (configurable in /etc/named.conf) containing the 
named cache (mine is /var/named/data/cache_dumb.db, don't remember if 
this is the default).

This will not clear the current cache in RAM, just output it to file.

Hope that helps,
Andrew
