1. How to Create a DNS server on Linux: Environment assumptions

One or two machines, one LINUX, The Machine name LINUX, the domain name tongqiang. cnIP address is 192.168.0.5, the other machine is WIN98, The Machine name tongqiang, And the IP address is obtained from the DHCP server on LINUX.

2. Create a DNS serverSuppose that your DNS package has been installed and you choose to install the DNS server when installing LINUX)

To create a DNS server, you only need to modify the following files.
