After centos6 is installed, the ifconfig command does not have the eth0 address and only the lo loopback address. Check the eth0 address: Obviously, the previous "no" must be changed to "yes" and then saved and exited. Restart the network: service network restart Then use the ifconfig command. Here, I use commands to obtain ip addresses. In fact, there is no need to be so troublesome. You can use ifconfig to contact the value here. Of course

implement, the configuration is as follows (other configuration is unchanged, only the LAN port configuration is modified):Interface gigabitethernet0/1 port link-124.133 . 33.223 the 10.1. 20.200 the 172.19. 10.253 255.255. 255.0The flow chart is as follows:The client's request traffic is dnat by the firewall to the Web server, because the previous snat operation of the firewall, so that the Web server's reply data must go through the firewall again, the firewall through the NAT mapping rel

There are a number of solutions available on the Internet, mainly in the following ways:1 shut down Windows Firewall;2 Turn off IPv6 or set IPv4 preferences, specifically: In Device Manager, Show hidden devices, disable a network device beginning with "Teredo", Increase in Eclipse.ini file (last line parameter) OpenFile-vmargs-djava.net.preferipv4stack=true 3 Turn off the virtual NIC (virtual network adapter created by VMware, VirtualBox, etc.);My first do 2, 32 steps, have no success, f

Recently learned about the loopback file system for Linux. It's really interesting.The so-called loopback file system, which is different from the conventional file system, the general file system is built on the device, and it is built in the file.Regardless of the file system, it needs to be mounted before it can be used.Check out the loopback file system below

IPV6 and loopback address are short for Internet Protocol Version 6. Internet Protocol is translated into Internet Protocol ". IPv6 is the next-generation IP protocol designed by IETF (Internet Engineering Task Force) to replace the current version of IP protocol (IPv4. Currently, the version of the IP protocol is 4 (IPv4 for short), and its next version is IPv6. IPV5 has been reserved for the Internet information flow protocol developed before IPv6.

The loop port has a very wide application in practice, and this article is about the use of loopback mouth. BGP Update-source Because the loopback mouth as long as the router is still alive, it will always remain active, so as long as the BGP peer loopback to meet the route can be reached, BGP can be established, in general, BGP use of

The loopback group policy is also called Group Policy loopback processing. It is a method that can limit the execution of group policies after debugging. Group policies are divided into two parts: the upper part is the computer policy and the lower part is the user policy) The loopback process allows the Administrator to execute the user policy based on the compu

The PC local loopback address 127.0.0.1 is often referred to as the local loopback address (the loop back addressing), which represents the device's local virtual interface, so the default is seen as an interface that never goes down. also has a similar definition in the Windows operating system, so it is usually possible to ping this local loopback address

Whether it is linux, unix, or windows, there is an IP address such as 127.0.0.1. This is a special IP address called the host loopback address. Open the/etc/hosts file, with at least 127.0.0.1. In daily work, it is very likely that the loopback address is used to complete a certain task. However, there are still few articles about the usage of the loopback addres

possible to have the so-called direct-link routing (that is, chain-level routing), so the price of using a 32-bit prefix IP address is to manually add a clear route to the target of 32-bit IP address as the last hop. So far, I have divided the IP address into two uses, the first one used to mark the host, I use the 32-bit prefix address, and the second purpose I used for addressing, performing standard IP routing. According to the previous description, the IP address of the host can not be conf

The local loopback address, which does not belong to any one of the class address classes. It represents the local virtual interface of the device, so the default is to be considered an interface that will never go down. There are similar definitions in the Windows operating system, so it is usually possible to ping the local loopback address before the network card is installed. It is generally used to che

1. After the LVS scheduler receives a request packet whose destination address is VIP, it changes the MAC address to the MAC address of RSP and sends it to RSP through the switch (Link Layer. 2. After receiving the request from the RSP link layer, the request is sent to the IP layer. The IP layer needs to verify the target IP address of the request. Therefore, RSP needs to configure a VIP loopback device. In this way, the IP layer of the RSP receive

Install the loopback Nic in Windows 7 17:18:41 tags: original works, which can be reproduced. During reprinting, be sure to mark the original source, author information, and statement in the form of a hyperlink. Otherwise, legal liability will be held. Microsoft loopback adapter (Microsoft loopback Nic) is similar to a virtual Nic. It can be installed on a Window

From the Loopback interface, call Linuxer and Cisco NP/IE.NA, NP, and IE will be exposed to the loopback interface all day long. during training, they will learn a lot about loopback from books, many review outlines have two full pages to summarize the role of the loopback interface.Linuxer will also come into contact

Na,np,ie all day will be exposed to loopback interface, they in training, will learn from the book a lot about loopback, a lot of review outline will have a full page of paper will loopback the role of the interface summed up so that people can not help but want to back down.Linuxer will also come into contact with this interface, but in the name of more than the

When you cannot connect to the Internet, there are times when you need to do some experimentation to require that the host system and the virtual system interconnect. At this point, you can solve the demand by configuring the loopback network card. This article describes a brief step, starting with the Internet. First of all, the reason for this is to evade the research on VMware Network settings. When our work is not focused on the network, there is

Group Policy is applied to a user or computer in some way, depending on where the user and computer object is located in Active Directory. However, in some cases, the user may need to apply the policy only based on the location of the computer object. To apply a Group Policy object (GPO) only based on which computer the user is logged on to, you can use the Group Policy loopback feature. More information To set the user configuration for each comput

This article mainly introduces the method of implementing the Serpentine matrix, the loopback matrix and the digital spiral matrix in PHP, and analyzes the concept of the Serpentine matrix, the loopback matrix and the digital spiral matrix, the expression method and the PHP implementation technique with the concrete instance form, and the friends can refer to the following Specific as follows: The

Depending on the needs of the network, it is unavoidable to use a local loopback network card, such as on Windows 7. The installation method of the local loopback network card in Windows 7 The old party has been introduced in the blog. How is it different in Windows 8? Both systems are installed in the same way, and can be done through Device Manager and command-line. But the difference is the "local
