Bind9 dns zone not updating
For the purpose of this guide, I will be using three systems, one for Primary DNS server, other for secondary DNS, and the third one for DNS client.
All systems are running with Ubuntu 16.04 operating systems. Caching name server saves the DNS query results locally for a particular period of time.
I'll get to install 2x 1U servers with Ubuntu server 9.04. What folders/configuration files do I need to transfer?
Will I achieve anything if I use Webmin avoid using Webmin.
First, if at all possible, do not expose your master server (the one where all the changes should occur) to the internet.use rsync or scp or some other method of actually copying the files from the old server to the new (even ftp will do)true, but that only applies on the master anyway, comments will never propagate to the slaves.So, for interesting records, I use a TXT record and append info.Even if it means building a small VM session to host a hidden master, it makes moving stuff around and keeping it secure far easier.As an example, here's part of my bind layout (in /etc/bind): -rw-r----- 1 root bind 2.6K 2009-08-07 -rw-r----- 1 root bind 112K 2009-07-24 named.-rw-r----- 1 root bind 112K 2009-07-24 named.-rw-r----- 1 root bind 792 2009-07-01 named.-rw-r----- 1 root bind 834 2009-07-01 named.-rw-r----- 1 root bind 373 2009-07-01 -rw-r----- 1 root bind 131 2009-07-01 populating a new master by first making it a slave is a bad idea - it loses the original line order and formatting of the zone files, including all comments.
