enriquelg/dns-server repository overview

⁠DNS Server for edt.edu (Test Environment)

This repository contains a DNS server configuration specifically designed for testing purposes within the edt.edu domain, operating on the local network 192.168.1.0/24.

⁠Example Usage

To run the DNS server in a Docker container, use the following command:

docker run -d --name dns-server-m08 -p 53:53/tcp -p 53:53/udp enriquelg/dns-server:v2

⁠Verification Steps

After starting the DNS server, you can perform the following checks:

1. Check Connectivity to Google:

   nslookup google.com (Replace with the Host IP where the container is running)
   

   Copy

2. Check Local Domain Resolution:

   nslookup 192.168.1.10
   

   Copy

   Expected Output:

   10.1.168.192.in-addr.arpa	name = dns.edt.edu.
   

   Copy

3. Configure the Local Resolver:

   To set the Docker DNS server as your nameserver, add the following line to your /etc/resolv.conf:

   echo "nameserver (Host IP where the container is hosted)" >> /etc/resolv.conf
   

   Copy

   Alternatively, you can edit the file using vim:

   vim /etc/resolv.conf
   

   Copy

   Add the following line:

   nameserver (Host IP where the container is hosted)
   

   Copy

⁠Notes

• Ensure that the Host IP matches the IP address of the machine where the Docker container is running.
• For changes to /etc/resolv.conf to take effect, you may need superuser privileges.
