2 primary DNS server

[Rgomes]

Hi All,

I am going to configure 2 DNS server on 11i.
Please help on these issue:

1. Right now I have BIND ver 8.1.2, is it ok to run BIND 8.1.2? Should I download the latest BIND( 9.2.0)?
2. I like configure 2 primary DNS server for my network with real IPs. No slave namesserver. Is it OK also? Or I have to configure it as primary and slave?

Thanks in advance,
Richard

You can configure both as primary servers without any trouble...but why? It will cause you to do double entry on both systems. It would be better for you to have one primary server and the second as a slave server. The slave server can act as a primary to other servers if that is why you want to masters.

There are valid reasons to have two primary DNS servers. All you have to do is keep the databases up to date manually. In a static environment, this should not be very hard.

I have three primary DNS servers at my web hosting business. Every hour they borrow the DNS zone databases from the main server via cron. The reason there is no Master/Slave relationship is that if there is a major hardware failure, I don't want these servers wasting a lot of cpu and bandwidth trying to update that way. I don't need the syslog files filling up either.

BIND 9.2.0 is a must. It has substantial security enhancements over prior versions, comes with the dig command and is extremely simple to install and configure.

As the saying goes, Go for it.

DIG is freely available on the Internet for many Unix platforms. It was developed by Steve Hotz and Paul Mockapetris. The latest greatest version comes with any recent BIND distribution. You don't need to install the whole BIND package - once you've built it, just install the "dig" binary.

HI James, SEP, Berlene,

Thanks to you all for your outputs. I am going for 9.2 and also for cron update.

Thanks and best regards
