BIND DNS Server named.conf and chroot error after upgrading Virtualmin

Subject: BIND DNS Server named.conf and chroot error after upgrading Virtualmin


Good day from Singapore,


I have upgraded Virtualmin web hosting control panel Master Server to the following versions on the evening of 1st Nov 2022 Tuesday.


Webmin version: 2.001

Virtualmin version: 7.3

Usermin version: 1.860

Authentic theme version: 20.01.1:5


However, after the Virtualmin and Webmin upgrade, I get the following error messages.


Information!


Virtualmin's configuration has not been checked since it was last updated. Click the button below to verify it now.

Button: Re-check and refresh configuration


Checking Configuration

=======================


The status of your system is being checked to ensure that all enabled features are available and properly configured ..

Your system has 7.63 GiB of memory, which is at or above the Virtualmin recommended minimum of 256 MiB

The BIND DNS server version 8 or 9 does not appear to be installed on your system, or has not yet been set up properly in Webmin's BIND DNS Server module. If your system does not use BIND, it should be disabled in Virtualmin's module configuration page


 .. your system is not ready for use by Virtualmin


Then I navigate to Webmin > Servers > BIND DNS Server. It says:


The primary configuration file for BIND /var/named/chroot/etc/named.conf does not exist, or is not valid. Create it?


Options:

-  Setup nameserver for internal non-internet use only

-  Setup as an internet name server, and download root server information

-  Setup as an internet name server, but use Webmin's older root server information


Button: Create Primary Configuration File and Start Nameserver


All along, ever since the initial deployment of my Virtualmin web hosting control panel on 18 Oct 2021, I have never run BIND DNS Server in a chroot environment. After upgrading Virtualmin last night, the configuration was suddenly and unexpectedly changed to running BIND DNS Server in a chroot environment. I have no idea why and what happened.


So I did a Google search and found the following discussion threads.


[1] BIND DNS Server is uninstalled after the last upgrade

[2] Prevent OS updates from chrooting Bind

Link: https://archive.virtualmin.com/node/53785


Solution

=========


After reading through the above discussion threads, I have solved the problem by performing the following steps.


Click Webmin > Servers > BIND DNS Server


Click Module config at the top left hand corner.


Chroot directory to run BIND under: choose None


Is named.conf under chroot directory? choose No


Click Save.


And now BIND DNS Server should be back running normally, without chroot environment. It will revert back to using /etc/named.conf and zone files in /var/named.


Problem solved! I hope this guide is useful to you.

How the Singapore Government cheated my family of a HDB flat (Draft 22 Aug 2023)

Subject: How the Singapore Government cheated my family of a HDB flat (Draft 22 Aug 2023) It is a Well-Known Fact that government(s) invented mental illness to punish and torture people (and their families) who criticise the government or say bad things about the government. The Singapore Government rewarded my mother with a mental illness (schizophrenia). By leveraging mind control technology, the Singapore Government is able to make my mother hear voices in her head and trick her into believing that her neighbors are scolding her and targeting her everyday. Yes, the Singapore Government resorted to using this trickery. My mother firmly believes that her neighbors are scolding her and targeting her everyday. So we sold off our 1st HDB flat at Bedok North Street 3 and purchased another HDB flat at Yishun without careful consideration, planning and advice. When we moved to the HDB flat at Yishun, my mother still firmly believes that her neighbors are scolding her and targeting her every
