ObjectiveIn the previous article, "Raspberry pi set automatic dialing, build no-line by environment" , the author uses HOSTAPD and UDHCPD programs to create wireless hotspots to achieve address assignment and DNS server settings. This article will make improvements to the Raspberry Pi AP based on the previous environment: use DNSMASQ instead of UDHCPD to implement DNS and address leases, and encapsulate AP functionality as a service

I have already studied bind's cache dns server. Today I have studied dnsmasq's dns Cache and found that the configuration of dnsmasq is much simpler. It is better for new users to get started with complex configurations than those of bind, after all, it is difficult to maintain the service after it is used locally.

Following the installation of open VSwitch in the Ubuntu14.04 installation configuration Open VSwitch, here we will create two KVM VMs and automatically assign private IP addresses to these two VMS through DNSMASQ.The virtual machine and host network structure diagram are as follows:Test Environment Description:1) Test private network segment: 172.17.0.0/242) Test VLAN tag:100The following is a brief introduction to the entire configuration process:1, installation

Note that its design is kept simple very intentionally, I. e .:
-It takes raw DNS query packet data as input, and returns raw DNSAnswer packet data as output
(This means that two similar queries that encode the DNS nameDifferently will be treated distinctly ).
-The ttls of answer RRS are ignored. Our DNS resolver library does not useThem anyway, but it means that records with a TTL smallerConfig_seconds will be kept in the cache anyway.

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 deployment of virtualization and large data environments.DHCP service

What is DNSMASQ (excerpt from the network)
DNSMASQ provides DNS caching and DHCP service functionality. As a domain name resolution server (DNS), DNSMASQ can increase the speed of connection to visited URLs by caching DNS requests. As a DHCP server,
Using dnsmasq to build a small Intranet DNS dnsmasq is a very small dns server that can solve small-scale dns query problems, such as the Intranet of the IDC. The general idea of www.2cto.com is as follows: Configure dnsmasq as the DNS Cache Server and add local Intranet resolution to the/etc/hosts file, when querying an intranet machine, the hosts file is querie
When it comes to dns, you will always think of bind. Although bind is powerful, it is too complicated and it is a headache for configuration. Killing a chicken with a knife is not a zombie, but a fear that the knife will hurt your feet. Dnsmasq is much easier to use than the dns ancestor bind. It can be used as a forward dns proxy or an internal pure dns server. Install apt-g in debianubuntu

Running your own dnsmasq with libmongod
On Linux host servers, libmongod uses dnsmasq to service the virtual networks, such as the default network. A new instance of dnsmasq is started for each virtual network, only accessible to guests in that specific network.
If you are running your own "Global" dnsmasq, then this c
Purpose: When a LAN User accesses a domain name, the user intercepts the access to the specified IP address and caches the IP address to save bandwidth.
