Title: Slave DNS Server & Manager Question
Post by: Starburst on August 24, 2020, 09:11:47 PM

I just setup Slave DNS Server & Manager on CentOS 8, everything seems to be working, but when I access CWP's DNS Zone List, it doesn't show any of the zones.

Towards the bottom of http://wiki.centos-webpanel.com/slave-dns-server-manager-download-version, is:

CWPpro WebServer configuration

Edit File: /etc/named.conf and add this in options section before closing }

//Slave dns configuration
allow-transfer {111.112.113.114;};
allow-recursion {111.112.113.114;};
also-notify {111.112.113.114;};
masterfile-format text;


My question is, is this for the Web Server or the DNS Manager Server?

Further up in the instructions, it has you already edit this file.

Thanks

The setup is for Web Server ( where u put your domains with website and where is running a master dns server by default - from where u want to transfer to your dns servers which will be public for your domain hosted on CWP )

Example from my setup

in /etc/named.conf , before

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};

Add this

allow-recursion { any; ::1; ip1; ip2; };
allow-transfer { 127.0.0.1; ip1; ip2; };
also-notify { ip1; ip2; };
masterfile-format text;
};

( Where ip1 and ip2 - is ex: 111.112.113.114 )

I had it placed after:

allow-query     { any; };

And before:

/*
         - If you are building an AUTHORITATIVE DNS server, do NOT enable recursion.


Should I move it to where you suggest?

if u added after
allow-query     { any; };

add only

allow-recursion { any; ::1; ip1; ip2; };
allow-transfer { 127.0.0.1; ip1; ip2; };
also-notify { ip1; ip2; };
masterfile-format text;

It should be fine ... but u will need configure allso the slave dns to permit trasnfer of zone AXFR

on a slave DNS server
in options tag ( global settings )

allow-query     { any; ip1; ip2; };

where ip1 and ip2 master dns server - where is domain zone defined

and also on slave dns - zone define like:

zone "domain.com" { type slave; file "slave/db.domain.com"; masters { ip1; };};

Left out the recursion (cache) line, because can't that allow for a potential DDoS attack?
