Confused abaut Primary and Secondary DNS Servers configuration.

[cautbur]

I am confused abaut primary and secondary dns servers configuration. i have read a lot of manuals tutorials abaut how to do it, but i think they do not adapt to my needs.

I set up two servers (like a tell on previous post). I now have configured second server (slave secondary dns server) to run in multiserver mode.

I configure two server entries in my administration panel.

If i mark "Is mirror of Server" on second server configuration i lost the posibility of create new websites into it. If i unmark seems dns replication in secondary dns server dont work.

I want to have two servers, controlled by one control panel in multisite mode I can get it if i not mark "Is a mirror site" in server configuration, i think this is the corret way. Mirror is for redundant purposes (i think) not for two independent server alocating diferent websites. So i have to active other services also like mail, etc in the second server.

I want also have my own nameservers ns1.domain.com ns2.domain.com. So i have created a zone with A record "ns1" pointing to primary server ip, and NS record domain.com pointing to ns1.domain.com. I have the same records for the other server with secondary server ip (A ns1 second ip and domain.com to ns2.domain.com).

Is this correct?, i have to do anything in secondary dns?. What i have to do in order to get the ns1.domains.com zones transfered to ns2.domain.com? without mirror one server into other one (i dont want mirror sites, etc).

I could get zone transfer by hand one by one, but i dont want to do this because i think this is not the way, the way is tranfer all zones froms ns1.domain.com to ns2.domain.com automatically.

Thanks for your responses and your help. I really need help with this.

For secondary DNS i`m using:

puck.nether.net.

If i learned right, the secondary server need be in another IP.

The secondary as mirror i think will work as load balance for your internal network, frst requisition will ask ns1.server.com, second will ask ns2.server.com, etc... Not sure if is it.

For the second DNS (puck.nether.net), i just set to allow zone transfer.
On the primary DNS you need add an A record point for your domain to your public IP ns1.yourdomain.com

Yes, thats correct.

You can create primary and secondary dns that gets synced automatically like this:

1) Create a new primary zone on the ns1 server, this zone has one ns recod for the ns1 server and a second ns record for the ns2 server plus a A-record for ns1 that points to the ip address of the first server and a A-record for ns2 which points to the IP address of the second server. In the field "Allow zone transfers to
these IPs (comma separated list)" of this zone, add the IP address of the secondary ns server. In the first step, we created the full primary dns record.

2) In this step, wer create the record for the ns2. Go to DNS > Secondary DNS > Secondary zones and click on the add button. Enter the zone name in the zone field (the zone is the same that we created in 1) and in the ns field you add the IP address of the primary dns server (your first server) and click on save. Bind will now transfer the zone data automatically between the servers and will get updates from the primary server automatically.

Thanks Till and Wisdown.

Till your response is the solution. Thanks, i was trying for hours. Now works perfectly.

So my conclusion is that althought i installed first server as standar mode, setting up second as an expert mode connected to first work fine, and do not have to reinstall first server ispconfig in expert mode.

And second conclusion is your response, "how to setup two dns servers master and slave" could be a good title on how-to forge.

I think if i want, in the future, add a third dns slave server i will only have to do the same with the third server (add an entry to secondary dns of first server and add the zones needed in zones).

Thanks a lot. Best regards Till and Wisdown.

Hi all,
I followed this howto:
http://www.howtoforge.com/how-to-run...ian-squeeze-p2

And this section post:
2) In this step, wer create the record for the ns2. Go to DNS > Secondary DNS > Secondary zones and click on the add button. Enter the zone name in the zone field (the zone is the same that we created in 1) and in the ns field you add the IP address of the primary dns server (your first server) and click on save. Bind will now transfer the zone data automatically between the servers and will get updates from the primary server automatically.

In ispconfig >DNS>secondary DNS
I have Server: it's the primary or master ( I can't see the secondary)
Client : any
DNS zone: ns2.domain.com
NS : IP of primary server/DNS
Allow: IP of secondary DNS
Active : check

The two server just don't sync...

In the ns2 log I have
Jan 15 16:51:02 dns2 named[28492]: client xx.xx.xx.xx#12282: received notify for zone 'domain.com'

But there is no pri.file in the /etc/bind or /etc/bind/slave
If I query the ns2 IT doesn't answer for the domain.com

How can I know if they sync? Is it in the log somewhere?

I'm just lost here, please any solution idea or trail to look...

Thanks

Any other lines in the log of the ns2 server? There should be either a success or a failure message after this line. You might also want to check if the bind server can write to /etc/bind/slave

This post is directed to Wisdown, or anyone else who is/was using puck.nether.net as a secondary DNS server.

WHAT HAPPENED TO PUCK.NETHER.NET?

I have been using puck.nether.net secondary DNS for several years, recently I noticed some dns errors on my domain. I traced it to puck.nether.net using the cool free DNS tool http://ww2.infoblox.com/services/dns_advisor_tool.cfm

It seems as though this service has fallen off the face of the internet. Is this true or am I being stupid? My last status message from puck.nether.net was on Nov 29, 2012.

Any comments?
