Setting up Linus based DNS sesrver

Hi,

 We have DNS running on sparc and solaris.

 Client now wants DNS to be ported to Linux.So I would like to know opinions of System Admins having experience in maintaining DNS on Linux,in terms of performance ,reliabilty,vulnerabilty etc...

 Honestly I want DNS only on Solaris and sparc as I believe it has proved its merit already and I don't want this experimentation on Linux to hurt things.

Regards,

Karthikeyan

I agree with jlevie regarding the reliability, response and maintainability, but I would suggest an alternative to the traditional DNS server. The alternative would be djbdns (//http://cr.yp.to/djbdns.html).

I consider that this package would make the Linux DNS server even more reliable than the Solaris version. Also as a big advantage is the easiness in configuration and mainenance.

Please feel free to ask for more info on this solution (I am using it right now for an ISP and I consider it to be the best).

Best regards,

There is a good howto on my LUG's website on how to make a caching DNS server. Here is the URL:

Hi Levi and Razvan,

  Thanks both of you?can you pls update me more on DNS propagation?

 That is,does DNS propagation happen automatically or is there a way to force propagation(by means of commands) like forcing zone transfers?

Regards,

Karthik
An authoritative DNS server will send notifies to each of its secondaries any time that it is started or asked to reload its zone files, unles you specifically prohibit it from doing so. Slave server, if it's been too long since they've updated their slave zones, will request that the authoritative server  provide the SOA record so the can check the serial.

So yes, DNS propogation happens automatically and is a pard of BIND regardless of platform.
