Comments on How To Run Your Own DNS Servers (Primary And Secondary) With ISPConfig 3 (Debian Squeeze)

This is really informative....thank you...

Great post, thanks for sharing. i am wondering whether a hosting company allow its clients to do such a DNS setting.

Why wouldn't they?

Please tell us what you mean by 2 servers.

Does this work on 1 dedicated server that has no virtualization if you have 2 IP addresses, please?

Thanks

Hello there,

I followed this tutorial, and tried to set-up my nameservers (ns1.new-internet.org and ns2.new-internet.org) but after i created them and added a record for new-internet.org they didn't worked at all:

:~$ dig @ns1.new-internet.org any new-internet.org

; DiG 9.7.1-P2 @ns1.new-internet.org any new-internet.org
; (1 server found)

please, i know, i must post this at the forum, but PLEASE help me out ! All my (20) domain's don't work right now, becouse of this

Is it possible to use 4 nameservers? Is it better or not necessarily?

You may use as many nameservers as you like with this setup. Having 4 nameservers is only necessary if you have a really huge setup and you either expect that more than one nameserver fails at the same time or that you have so many dns requests that 2 servers can't handle the load.

 In want to use 4 DNS servers (with this setup) just for faster accessibility (for visitors).

For example DNS servers at:USAEUROPEAFRICAASIA

..will be better/faster accessible (for visitors from any country) than 2 DNS servers in one country?

Thank you for your reply:)

Make sure you replace 1.2.3.5 with the IP address and server2.example.com with the hostname of your secondary DNS server!

- This line are added below/after wrong data CREATION. HOW HOW EDIT WRONG DATA NOW?

You would change the 'users' table in the mysql database; it should be something like:

  update users set Host='4.4.4.4' where User='root' and Host='1.2.3.5';  flush privileges;

Make sure you replace 1.2.3.5 with the IP address and server2.example.com with the hostname of your secondary DNS server!

- This line are added below/after wrong data CREATION. HOW HOW EDIT WRONG DATA NOW?

I have installed "Install ISPConfig Web Interface (y,n) [y]: <-- n" by mistake on second DNS server. How I can remove this? Or is it not necessary/not important?

 Please HELP! :)

Just looking to setup a secondary (Slave) DNS server and was wondering if this would work with an existing ISPConfig 3 install?  Could I just run the updater after entering the root mysql commands?  Thanks

How do u create ur own dns control panel server from scratch?

Excuse my ignorance, I have installed ISPConfig 3.1 automatic in ubuntu 16.04 and I have problems to add new domains, I would like to have ns1.mydomain.com and ns2.mydomain.com. In order to register new domains, how is this possible?

I want to point out this line, maybe it needs correction, although it seems to affect nothing. I believe A records are created through your hosting control panel, and not your domains registrar.

Note: DNS A records for server1.example.com and server2.example.com must already exist (you can create them through your domain registrar's control panel)

Any help! 

I have gone through the whole process and everything seems to be working fine and thats why I'm surprised, cos I was unable to create dns A records at my Web Host Company as stated in the tutorial but the welcome page is well displayed fine. 

Secondly some registrars wont authorize my nameservers, dont know why

I am running ISPConfig 3.1.13 but in the control panel when I go to (Step 4.) System > Server Services. And Select the server it doesn't show Is a mirror of Server.

Thanks for all your work!

This option must be there, it is hard coded. Maybe you clicked on System > server config instead of System > server services?

Hello,

We are trying to set this up on stretch with mariadb 10.1 and php7.1 and teh slave server can't connect to the master. I think the problem may be that on both servers, the command mysql -u root -p does not allow mysql login, even though the password is correct when supplied. To login to mysql only the command mysql -u root -p'password' (with no space after the -p and the password which must be in single quotes). 1) Is this a mariadb error? 2) Is this the cause of the failure of the ispconfig3 install on the slave server when it can't connect to the master?  Thanks for help. Wa are proud ispconfig3 users and manual owners!

We had earlier problems connecting to mysql on the command line. Further research indicated that passwords longer than 70 characters were problematic, so a shortened password solved that problem (in the installation of the dns slave). Now we have a different problem - we tried with php7.1 and then downgraded the entire server to 7.0 and we still get the following error at the last step of the ispconfig3 installation on the dns slave server:

MySQL master server database name [dbispconfig]:

PHP Fatal error:  Uncaught Error: Call to undefined function mb_detect_encoding() in /tmp/ispconfig3_install/install/lib/mysql.lib.php:448

Is there a fix for this? What do you recommend? Thanks.

The PHP mbstring extension is missing in the PHP that you installed. Install php mbstring for the used php version.

Hello! I'm trying in a debian to do a hosting but I can not get the dns to spread. In the DNS zone which IP has to be set? I have put the public IP (the one that gives me in a web called which is my ip). Is that I have tried both ways and I do not get it in any of the ways, do I have to do some more configuration so that the hosting is accessible from the internet? Thank you very much for your manual and I hope you can help me.

Since we run with php7.2, do we still need php5-cli php5-mysql php5-mcrypt? 7.2 doesnt have mcrypt as far as i can find... 

Thanks for your great tutorial

I have a VPS with ISPConfig 3.1 on Centos 7.7 

I have a master domain name that I use it as my DNS Server address alias (teslagps.com)

multiple Domain uses this as name server (ns1.teslagps.com, ns2.teslagps.com) and everything works fine from the localhost.

I use DNS-Wizard to add a new domain to the DNS server so I did n't change any default value but now

sometime I can reach my domains sometime I can't! I can not get PING from these domains but nameserver has PING.

and Sometime when I open one of my domains I'll face with ("503 Service Unavailable" Error)!

and finally sometime my Alias domain for .COM domains like .IR not working!!!

I'm in wonder! please guide me!

it's dig report for one of my domains(teslacnc.com)

Hello,

We have this running great for the master and the first slave, but we have not been able to get the ns3.slave to work. Does this tutorial also work for a master and 2 slave setup? Whenever we try to use the 2nd slave as nameserver, the request is denied. Is there a table in the db to check on this?

the second slave is also reported as "not available" on differend servers/systems using pdnsd dns cache server, for example, but the master and 1st slave are reported as working!

> Does this tutorial also work for a master and 2 slave setup?

yes, you can add as many slave servers as you want. Just install them in the same way you installed the first slave server and always choose the master server to be the master of that slave.
