dns server not responding

Learning stems from the solution of problemsDuring the previous time, an Oracle software was installed on the virtual machine, the network connection of the virtual machine and the host machine was bridged mode, the static IP address and the gateway address were manually set, but the browser of the virtual machine could not be used.So through the ping test, the host ping www.baidu.com can ping, but the virtual machine said unknown host, so let the virtual machine ping the host ping the IP addres

For the wan nic, we configure the IP address and mask for it, without configuring the gateway and DNS. For LAN NICs, the IP address and mask are also configured. Because it is 10 private network segments, the mask can be used by default. Then we set up AD because we need to deploy DHCP, and DHCP requires AD to operate normally. Then we select the DHCP server, DNS

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. Check the operation.System: CentOS 5.4Ip: 192.16

Guide DNS (domain name server, nameservers) is the server that is transforming the domain name and the corresponding IP address. DNS holds a domain name and the corresponding IP address (IP addresses) table to resolve the domain name of the message. Let me give you a brief look at the configuration of the

hierarchy, and any one domain is at most one parent domain, but can have multiple or no subordinate domains. You cannot have the same subordinate domain or host name in the same domain, but you can have the same subordinate domain name or host name in different domains. 1. root domain: (root domain) root domains are only one, the root domain is the default, generally do not need to be expressed. The DNS namespace is managed by the InterNIC in the Un

Because the enterprise office needs, the author has deployed the DNS server in the local area network, all client's DNS server address parameter is set to this server's IP address. Also, a domain named "rtj.net" has been created in the DNS

Although Linux has not made any notable progress in the world of desktop computing, It is very famous as a network server

The service provided by the DNS server is the task of converting the host name and domain name to an IP address. Why do I need to convert the hostname and domain name to an IP address? This is because when a client on a network accesses a resource on a server, the user enters the browser's address bar with the easy to remember host name and domain name. The conne

Create a forward lookup zone ynkm.com and create a host record under this zone webserver,ynkm.com. Action steps are as follows: ① Open the (INSMGMT console window, select the DNS server for which you want to create a forward lookup zone, and then select the Action-New Zone command in the menu bar, as shown in Figure 1.) ② pops up the New Zone Wizard dialog box as shown in Figure 2, which guide
