There are two mail servers 192.168.1.1 (under Windows host name b.test.cn) and 192.168.1.3 (Linux under host name is a.test.com). Configure the DNS server under Linux, and here are some of the files that were set during the configuration process. The specific contents of the/etc/hosts document are as follows: # Do not remove the following line, or various programs# that require network functionality will fail.127.0.0.1 localhost.localdomain localhost fc4192.168.1.3 a.test.com a192.168.1.1 b.test

Start the virtual machine Ubuntu system, open the terminal, use the following command to open and edit the network interface configuration file: sudo vi/etc/network/interfaces 2. Edit the document as follows: Auto lo iface lo inet loopback # Assgin static IP by Eric in 26-sep-2012 iface eth0 inet static address 19 2.168.91.200 #change to your static IP netmask 255.255.255

Here we see the shared IP address in the above image is the host IP addresses we purchased, and our domain name if a records parse this is right. Second, we can also use DNS to resolve This interface should be familiar to many friends, many of us are directly to see the

code is as follows A configured virtual host that wants to be accessed by the outside world must also be registered in the DNS (domain name system--nameservers server) or Windows system, because when a URL is accessed through a browser, you need to specify the IP address of that host. To connect to the Web server by this IP Therefore, when the virtual host configuration is complete, you also need to configure the mapping of the virtual host to the

its own buffer. The recursive query request flag is not valid at this point (see DNS header Introduction). The recursive query is shown in Figure 7-40.2) non-recursive queryThe so-called non-recursive query means that the first domain name server that receives the request can return reliable data (itself sometimes), or it can return pointers to other servers (equivalent to passing the baton of the query to the nearest nameservers). The difference bet

root server information. The server sends and receives not only your own domain information but also all the domain information on the Internet. Not every server has a registration entry for each domain name, but each server knows how to get information. Of course, because the list is updated regularly, it should be recorded regularly. The second area entry in the Named.conf sample file is a master field entry, meaning that the DNS server holds valid information for example.com, which all othe
