You should read these troubleshooting tips if you see bind9 debug servfail error code on your computer.
I have a BIND 9.6 instance that acts like a cacheuseful NS for the entire building, in addition, it is also relevant for the room area (“example” below):
How to set up BIND9 as a forwarding DNS server?
Configure Bind9 as a DNS Forwarder 1 Install BIND9 2 Configure as Forwarder. The bind (9) configuration files are located in our / etc / bind directory. 3 by adding our own zones. To add our own zones, we add a problematic file named zone.
"sample" zone Master type; File "Example"; The renewal policy provides the location of the DHCP renewal subdomain. TXT; ;;
Due to a criminal transition, we lost contact with the rest of the world, and some NS started responding to SERVFAIL; What made me happy is that the server was also previously unable to respond to requests for the sample domain.
What is the real reason for this behavior? Shouldn’t everyone be able to answer NS, because then they have the relevant data?
Edit: Config just shipped with Debian: Notes for root server and specific zones and zones for localhost and broadcasts.

You can go to troubleshooting # 1 to make sure your question is not answered immediately. However, there is a suspicion that the permissions on your regional file prevent the user from reading the file from the link.
I have set all the logging options in named.logging.conf and then use include in the main file:
logging siphon default_syslog // Submit most of the mentioned promotions to the syslog. local syslog2; Strict debugging; ; Audit_log approach // Send security messages to a separate file. Directory "/ var / named / system / named.log"; Deep debugging; Print time yes; ; Zero line Zero; ; The default category default_syslog; ; General category default_syslog; ; Security category Audit_log; default_syslog; ; Configuration of the default_syslog category; ; Category converter audit_log; ; Xfer-in category audit_log; ; Output category audit_log; ; Notify category audit_log; ; Client category audit_log; ; Network category Audit_log; ; Updating the audit_log category; ; The category requests audit_log; ; The blade server category is empty; ;;
What is SERVFAIL and how do I Fix It?
SERVFAIL’s response informs you that there is a problem with accessing your domain’s DNS server, or that it is not configured correctly. It seems like you are only answering A queries from your internet DNS machine, which might be the reason some nameservers don’t like your domain.
root @ dnsm02: / etc / bind # grep named.conf loggingenable "/ etc / bind / named.logging.conf";
Also, no one mentions views, but after you define views, all of your scopes can end up in specific views.

What is the difference between NXDOMAIN and SERVFAIL?
While NXDOMAIN is the DNS server telling you that the domain cannot be found, SERVFAIL is the DNS site that tells you, “Hey, I can’t generate a response for this expert request for you.” There may be a related technical issue with the DNS servers.
