I found many threads about setting up nameserver under one box.
Is that possible to have nameserver using two seperate servers' IPs?
For example,
1) ensim box. IP - 12.34.56.78. domain - abc.com
2) plesk box. IP - 78.56.34.21. domain - xyz.com
I want to setup nameserver for these two boxes using their primary IPs for the purpose of redundancy. These two servers are located at different location.
Does anyone know how to do it or tell me where I can find info?

It's pretty easy...

Configure one sever as master, and the other as slave. It should be in the documentation for Plesk and Ensim.

thanks for reply..but isn't that just repeat of my question?
i searched all document and internet last 4 days and found nothing related to this kind of question.

Server newbe here :)

A domain might need one IP# - but you'll need 2 IP# to set up a domain name server. Either abc.com or xyz.com can be the DNS (master) and the other server can be slaved to it.

Is either server up now? It'll make configuring easier. Also make sure to get to think of the problem in terms of abc.com and xyz.com - this make the IP issue easier to talk about.

2) plesk box. IP - 78.56.34.21. domain - xyz.com

As I said before I don't think Plesk supports slave zones yet...

Assuming you've got the control panels installed correctly, you should check the control panel's documentation to see how to add a zone in the DNS. I'm certain Plesk has that information in their manual, and it's fairly easy.

As for setting up a slave zone, after your main is set up you just add something like

zone "xxx.com" {
type slave;
file "named/db.xxx";
masters { xx.xx.xx.xx;
};
};

Basically, that should do it... You can put the file (3rd line) where ever you want, but I find it useful to put my zone files in a separate directory.
