This type of interface is the most widely used virtual interface, which is used on almost every vro. Regular See the following usage. 1 As the management address of a vro After the system administrator completes the network planning, Loopback interface, and specify an IP address as the management address on this interface. The Administrator will Use this address to remotely log on to the vrotelnet (Telnet). The address actually starts with the na

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.

With the official launch of Windows 8, many IT peers have started to use IT. The old party is no exception.Because my machine configuration is still good, I Installed VMware Workstation 9 on it and conducted many tests.According to the needs of the network, it is inevitable to use a local loopback Nic such as on windows 7.The Installation Method of the local loopback Nic on windows 7 has been described in t

Problem description:When installing Oracle 10 Gb, the first condition detection will appear"Checking Network Configuration Requirements... the check is complete. The overall result of this check is: not executed Proposal: Oracle supports installation on a system with IP addresses allocated by DHCP. Before installation, you must configure the Microsoft loopback adapter as the primary network adapter of the system. For more information about installing

Loopback check security feature is added in Microsoft Windows Server 2003 Service Pack 1 (SP1. it aims to prevent reflection attacks on your computer. therefore, if you use FQDN or a custom host header that does not match the computer name to access the computer, authentication will fail. How do I disable loopback check? Set the DisableStrictNameChecking registry entry to 1. ClickStart, ClickRun, Type reg

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

parameters in front of the detailed section can not see, only see the most behind notes or bugs part of the good, its bugs part has a detail center this topic:BUGS...On Linux systems with 2.0[.x] kernels:Packets on the loopback device would be seen twice;Packet filtering cannot be do in the kernel, so then all packets must is copied from the kernel on order to being filtered In user mode;All of a packet, not just the part that's within the snapshot l

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

In Unix-like operating systems,Loop Device,LoopbackDevice,VND(Vnode disk), orLofi(Loopback FileInterface) is a pseudo-device that makes a fileAccessible as a pseudo-device. A loop device may allow some kindData elaboration during this redirection; for example, the device mayBe the unencrypted version of an encrypted file. Since loop devices allow seeing a regular file as a device, theyAllow for mounting those regular files that contain an entire fileS

I recently used VMware Workstation7 for some experiments on Windows 7, and encountered the need to configure different networks. Because windows 2003 server is used to using the local back-to-ring Nic, you should also use it on Windows 7. The results are not as simple as you think. After a while, I found two solutions. As shown in the following figure. 1. Use the Device Manager 1. Control Panel --- Device Manager. Select a machine name, and click "operation" to add obsolete hardware. 1. Op

After centos6 is installed, run the ifconfig command without the eth0 address. only the lo loopback address is used to check the eth0 address. it is obvious that the preceding no address must be changed to yes, and then save and exit. Restart the network: servicenetworkrestart is effective now with the ifconfig command. I use commands to obtain ip addresses here. In fact, there is no need to be so troublesome. you can use ifconfig. here I will contact
