http://debugo.com/dnsmasq/ DNSMASQ is a compact and convenient tool for configuring DNS and DHCP for use in small networks. It provides DNS functionality and optional DHCP capabilities to replace services such as DHCPD (DHCPD service configuration) and bind, which are simpler to configure and more suitable for deployme

Please let me know if there is something wrong or unclear in this article. thank you! DDNS configuration instances (DHCP + DNSDDNS) are a basic task in network management. However, as the network grows, it will be very troublesome to frequently modify data files in the DNS region. Therefore, dynamic DNS came into being. Please let me know if there is something wr

Article Title: rapid integration of DHCP and DNS services in Linux networks. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Now the server running a lot of system services, although there is no problem in the middle, but still afraid, if there is a problem, is a few days of time no, tired of 4 of people things AH. So you have to backup everything. Ghost Backup is the system, but the service configuration is at any time in the change, can not always come to a ghost bar, say no display, very troublesome.Studied for an afternoon and finally implemented automatic DNS and

Some DHCPD server scripts start the program Configuring the client is to configure the NIC (eth0, eth1 ....). There are thousands of computers on the Internet, and each computer has a unique IP address. These IP addresses can be easily connected to the corresponding computer. However, IP addresses are abstract numbers that are hard to re
