Handling of zone transfers and notify messages

[Antoine Delvaux]

Hello all,

I'm currently busy trying to setup a server running NSD and new to that.  From what I read on the list archives and documentation, zone transfers are not automatically handled.  Suggestion is to use a cronjob and some people talked about using a plugin for such a task.

My question is, what is the mechanism the most used amongst people on this list?  And why?

My thoughts is that when running a server as secondary for domains you don't have control on, the notify messages are quite useful to provide a good service to your users.  On the other hand, too much notify messages can induce unneeded load on the server.

Is there a publicly available plugin that could solve both issues: accept notify messages and trigger a transfer if needed, avoid too many notify messages?

Thanks for your time,

Antoine.
