Where do I find the BIND9 configuration file?
Usually, all configuration files for BIND will be located in /etc/bind folder. Moving on, we configure the Bind9 server. We begin by tweaking the file /etc/bind/named.conf.options. In this file, we make changes like: Next, we create the zone files for our domains in the /etc/bind folder.
How does BIND9 set up a DNS zone?
For the rest of the domain name, it will query other DNS server and cache the result, behaving as a resolving, caching name server. In the first part we are going to deal with name resolution and then in the second part, we are going to set up the reverse name resolution.
How to create a forward lookup file in BIND9?
The forward zone file is where we define DNS records for forward DNS lookups. That is, when the DNS receives a name query, “host1.nyc3.example.com” for example, it will look in the forward zone file to resolve host1 ’s corresponding private IP address. Let’s create the directory where our zone files will reside.
Are there any logging options in BIND9 server?
There are two main options to BIND9 logging the channel option configures where logs go, and the category option determines what to log. If no logging option is configured for the default option is: Next we will configure BIND9 to send debug messages related to DNS queries to a separate file.
How does bind forward to outside resolving server?
However, it actually does none of the recursive querying itself. Instead, it forwards all requests to an outside resolving server and then caches the results to use for later queries. This lets the forwarding server respond from its cache, while not requiring it to do all of the work of recursive queries.
What happens if recursion is set to no in resolver?
If recursion is set to ‘yes’ (the default) the server will always provide recursive query behaviour if requested by the client (resolver). If set to ‘no’ the server will only provide iterative query behaviour. If the answer to the query already exists in the cache it will be returned irrespective of the value of this statement.
Why do we need a BIND9 DNS server?
The BIND DNS servers help to translate website names to IP addresses and vice versa. However, the installation steps of BIND can be confusing to many users. That’s why we help customers to set up DNS servers as a part of our Server Management Services. Today, we’ll see how our Support Engineers install Bind9 DNS server.
