How to reload your zone files

This article talks about how to tell named to reload your zone files.

ndc

ndc is the name daemon control interface.  You can use it to send various signals to the name server.  In the past I’ve always used kill or killall to restart named.  But lately I’ve started using ndc to achive the same thing.  Here’s how:

ndc reload

I was told this is a much cleaner and better way to achieve a reload and can avoid haning named.

I didn’t want to get into a debate with the person.  I’d never had a problem with my previous methods.  But nonetheless, the control interface is there and exists for a reason.  So rather than try to second-guess the system, I’ve now started using ndc instead.
