I installed the master2slave script, and change anameserver IP's the error given by DNSSTUFF.COM is that we have LAME nameservers.

What am i doing wrong?
 
ERROR: Your nameservers report glue that is different from what the parent servers report. This will cause DNS servers to get confused; some may go to the IP provided by the parent servers, while others may get to the ones provided by your authoritative DNS servers. Problem record(s) are:

ns2.ic-webserver.com.:
Parent server (k.gtld-servers.net) says A record is 85.12.39.152, but
authoritative DNS server (81.26.214.143) says it is 81.26.214.144


Concerns domain ic-webserver.com (nameserver)
 
Let's go through it carefully, to understand what it means...
Parent server (k.gtld-servers.net) says A record is 85.12.39.152
Click to expand...
The Parent server gets its information when you register the nameserver at the same registrar where the domain is registered.
authoritative DNS server (81.26.214.143) says it is 81.26.214.144
Click to expand...
The authoritative DNS server is the one listed in an A record at the nameserver(s) for the domain, in this case ic-webserver.com.

In the case of domain ic-webserver.com:

There are two nameservers: ns1.ic-webserver.com and ns2.ic-webserver.com.

The A record lookup at the gtld servers (they're synchronized and they all show the same) for ns2.ic-webserver.com returns 85.12.39.152.

The A record lookup at ns1.ic-webserver.com for ns2.ic-webserver.com returns 85.12.39.152.

The A record lookup at ns2.ic-webserver.com for ns2.ic-webserver.com returns nothing.

You need all your A records for your nameservers, both on the nameservers, and at the root servers, to say the same thing.

Perhaps for some reason the transfer isn't happening properly. Did you do the testing during the install?

Hi,

Thx for your reply Jeff.

Yes the transfer seems to go right.
But i'm not sure right now. There was something about user rights on the files as i think i found on this forum?
 
The failure is vey specific:
All nameservers respond:
ERROR: Some of your nameservers listed at the parent nameservers did not respond. The ones that did not respond are:
85.12.39.152

Is that nameserver running? Is its firewall (if any) open? This may or may not be a problem with master2slave DNS replicator, but certainly there's no way to tell from the information you've given.

YEs, all is running.
But do i need to redirect NS2 to the slave server?
On the slave is a ns2.ic-dns.com running. Do i need that nameserver also?

I don't know what you mean by redirect. the a record for ns2, on both your authoritative master server, and at the registrar (the gtld-servers.net nameservers) needs point to your slave server.

Jeff
 
Sorry for the confusion :(

I'll try to explain.

I have 2 servers.

The master server uses:
ns1.ic-webserver.com 81.26.214.143
ns2.ic-webserver.com 81.26.214.144

The slave server uses
ns1.ic-dns.com 85.12.39.152
ns2.ic-dns.com 85.12.39.153

My question now is how to setup my nameservers so i can use the slave server as my secondary nameserver?
 
One of two ways:

EITHER

change the nameserver list for all the domains hosted on your server (at your registrar) to show two nameservers; one from the master server and one from the slave server, and then change the NS records for all the domains you host, and also change your welcome emails so in the future they'll give out the right information

OR

change ns2.ic-webserver.com to point to the slave nameserver IP#, and change ns1.ic-dns.com to point to the master nameserver IP#, at BOTH the registrar where you registered those respective domains, and again in the A records for both ic-dns.com and for ic-webserver.com in the proper zones.

Personally, I think the second procedure much easier.

Jeff
 
Yes, but if you use Master2Slave DNS replicator in this scenario you'll need to isntall both master and slave software on both servers. I haven't tested it in this scenario.

You might be better off using the DirectAdmin Multi Server Setup instead of Master2Slave DNS Replicator, as it automates everything.
