Bind DNS how to disable axfr?

I want to prevent Bind to reply AXFR requests. How can i achieve this?

 

Do you want to disable axfrs at all or just disallow it for unknown dns-servers?

If you want to do the last one, why don't you use ACLs (http://www.isc.org/index.pl?/sw/bind/)

 

ok. i will do the last one using ACLs. i didn't know this
