Well, my question is, how would one possibly CLEAR the dns cache ?
I have a small problem I have noticed occasionally with Bind4.
Each time a certain .mil site connects to our www server, my BIND
server keeps trying to communicate with the DNS of the .mil
domain, even after disconnection. Sometimes for days and days.
I try re hupping named, and doing kill -9. Nothing works to clear
this from cache except to reboot. ( which seems silly )
I even tried a kill -INT and checked the output
of the dump.
