Set up a Simple DNS Server in the Lab
|
|
=====================================
|
|
|
|
While installing or using |prod|, you may require a |DNS| server that you can add
|
|
entries to for name resolution.
|
|
|
|
If you don't have access to such a DNS server, here is an example procedure for
|
|
standing up a simple Bind server on an Ubuntu 20.04 server.
|
|
|
|
.. rubric:: |proc|
|
|
|
|
#. Run the following commands to install.
|
|
|
|
.. code-block:: bash
|
|
|
|
$ sudo apt update
|
|
$ sudo apt install bind9
|
|
|
|
#. Use the following commands for a basic setup.
|
|
|
|
.. code-block:: bash
|
|
|
|
$ sudo ufw allow Bind9
|
|
|
|
$ sudo vi /etc/bind/named.conf.options
|

|
listen-on {
|
|
10.10.10.0/24; # this ubuntu server's address is 10.10.10.9/24
|
|
};
|
|
|
|
allow-query { any; };
|
|
|
|
# If this DNS Server can't find name, forward to …
|
|
forwarders {
|
|
8.8.8.8;
|
|
8.8.4.4;
|
|
};
