Updating root zone file bind Cam adult
However, taking two roles at the same time isn’t advantageous.
It’s a good practice to separate the two roles on two different machines.
Log into the two servers via SSH and run the following commands to install BIND 9 on Ubuntu 18.04/16.04 from the default repository.
BIND 9 is the current version and BIND 10 is a dead project.
In a previous article, I explained the steps of setting up a local DNS resolver on Ubuntu 18.04/16.04.
This tutorial will show you how to set up BIND9 on Ubuntu 18.04/16.04 as an authoritative-only DNS server with recursion disabled.
To follow this tutorial, you should have already bought a domain name.
Since we are setting up an authoritative DNS server, we need to disable recursion.
The TXT records are usually enclosed in double quotes.
If you add DKIM record, you also need to enclose the value with parentheses. Then run the following command to check if there are syntax errors in the main configuration file. The zone file on slave DNS server are loaded from a zone transfer, which is used to synchronize DNS record changes from master DNS server to slave DNS server.
recursion no; // enable the query log querylog yes; // disallow zone transfer allow-transfer ; . Each DNS zone has a zone file which contains every DNS record in that zone.
The master DNS server holds the master copy of the zone file. For simplicity’s sake, this article assumes that you want to use a single DNS zone to manage all DNS records for your domain name.
Each server needs only 512MB RAM and here are the hosting providers that I recommend. Once you have bought two servers, install Ubuntu on them and follow the instructions below.
