Bind Recursion on Dedicated Server - UK Web Hosting | Dedicated Server Windows and Linux VPS Forum

OK, so heres the scenario:

I want my 3 CentOS 5 DNS servers running Bind to be able to grab all the DNS zones on my Windows Plesk server and be able to have the zones grabbed every 30 mins or so.

Does anyone know of any scripts or how to configure Bind to do such a thing?

Your question is very technical so it may take sometime for someone with sufficient knowledge to answer your query!

Well I read his post on the very first day but din't have enough time to reply it. I am sorry for that though.

Ok.. Yes I have the solution and it is the hardest way to do it. I have been working on this to have cluster DNS for 40 Linux servers and about 15 Plesk servers. After alot of findings over the net I found that it is possible to set a master and salve combination to Sync data between two DNS servers but it is not possible to ask the DNS server to check the new Zones on the data server and then created a zone file as well as create an entry in the named.conf.

One file day I read about rSync'ing data over from a Windows server to a Linux server which was an ideal way to apply it and make things work my way.

So here is how I decided to do it:
-- rSync all the Zone from the /SwSoft/Plesk/dns/var/ on the DNS server to make sure that all the new zones as well as changes are reflected immediately.
-- Wrote a SHELL script to filter the rSync logs and insert an entry into named.conf.

I am successful till here but there are alot of other problems that I am still facing with the Shell script. As it works well if the amount of zones are 1000 to 1500 but the script fails to restart named if zones are over 5000. And it takes alot of time for DNS to restart due to high number of zones.

I have not looked into it for long now due to my personal and official work but I will post the tutorial for sure when I finish it.

I hope I was of any help and would welcome all new and better ideas.

Thank you so much for that Martin.

I look forward to reading the finished version.

Did you ever get anywhere with this Martin?

I've been researching the Bind options, and have found 'also-notify' and 'allow-notify' as options which could fulfill my desire. Does anyone know if this would work?

is there something like delegation? I have faint memories...

Let me confirm, What you are trying to do is: New domains are created on plesk, and you wish to read them from plesk and add to CentOS DNS servers?

Yep, that's it.

Plesk is on a Windows server running WIndows DNS and name servers are CentOS 4.5 running Bind 9.

Well, grabbing zone files every 30 mins & reloading the name server with the new data won't be a good idea. I think the time should be increased to grab n reload once in 3 to 4 hours. This would be beneficial for the DNS server as well for the website hostings too, just in case you need a backup of a deleted zone file or if you want to stop a bad zone from reloading, 30 mins would be very less time if the quantity is more... Just a humble suggestion...Let me know what you think on this

3-4 hours sounds fine to me. Do you know how I would go about doing this, Rock?

I've heard nothing more from anyone. Surely someone must know how to accomplish this. I'm kind of desperate to do this now.
