In this episode I will be building two Linux DNS and NTP servers using Ansible based on CentOS 8.0. This episode is a part of my video series on Building an Enterprise Network that I call Secured Enterprise Core Network (SECNET). The DNS and NTP servers will be used as a relay to reduce and prevent systems like the Active Directory Domain Controllers from reaching directly out to the Internet.
