ethernet loopback

Linux loopback NIC Driver Design, linux loopback NIC Driver Loop NIC Driver1. The difference between a back-to-loop network card and a common network card is that it is virtual rather than a physical network card. It is equivalent to concatenating the sending end and the receiving end of the common network card.2. in the kernel source code, the loopback Nic Progr

first, related loopback address basic concept What does the loopback address of a device on a router mean? The local loopback interface (or address), also known as the loopback address (loopback addresses). This type of interface is the most widely used virtual interface,

Enable the loopback access permission for the UWP application, and enable the loopback permission for the uwp Application Recently, I encountered a requirement for UWP to call WCF in the project. Considering that UWP cannot host the WCF Service (if possible or with similar technologies, please let us know), I wrote a WPF program to host the WCF Service, then use UWP to call the service. I didn't encounter a

During the installation of 11g, this machine encountered the need to install the loop adapter. My system is Windows 2003 Server. in the network environment of the lab, IP addresses are automatically allocated by DHCP. If Oracle finds that your machine is using DHCP, install the Microsoft loopback adapter to provide a static IP address. For details about the installation method, see: 1. Click start, and then click Control Panel ".2. If you are in t

data stream reverse packet to return to the next hop, the Snat address at this time the target address, because in the same network segment, so will be directly ARP , you need to add an ARP conversion rule: Arptables-t mangle-a output-d Next hop gateway address-j mangle--mangle-ip-s Knowing the problem and the solution, you can do it now. The goal of this article is to achieve a similar Cisco NVI, that is, a virtual network card in the virtual network card delivery process to achieve NAT. In vi

the Ethernet card. Here we use the Alloc_netdev function, which is defined in the Linux function asDefine Alloc_netdev (Sizeof_priv, name, Setup), where the first parameter represents the size of a member Priv space in the net_device structure, we do not use it here, so fill 0. The second parameter represents the name of the loopback network card, the third parameter is a function pointer, and the Setup fu

From: http://blog.csdn.net/ljinddlj/article/details/5935520 The loopback interface is a virtual network interface, which has different meanings in different fields. 1.TCP/IPLoopback interface in protocol stack In TCP/IP, the loopback device is a virtual network interface implemented by software, which is not associated with any hardware. Loopback interfaces are

1, Linux network interface of literacy(1) Naming of network interfacesThere is no naming convention, but the definition of a network interface name is generally meaningful. For example:Eth0:ethernet, typically used for Ethernet interfaces.Wifi0:wifi is a wireless LAN, so wifi0 generally refers to a wireless network interface.Ath0:atheros, generally refers to the Atheros chip contains the wireless network in

IEEE and 10GEA (Gigabit Ethernet Alliance) are the two most important organizations in Gigabit Ethernet standardization.Gigabit Ethernet standards and specifications are many, in the standard, the first 2002 years of IEEE 802.3ae, and then continue to have a new Gigabit Ethernet specification, such as the 2006 IEEE 802

1. To identify and manage network devices (such as routers and PCs), we usually use interfaces of these devices (including physical interfaces and logical interfaces: for example, vlan. However, although the device is not out of the network, the device cannot be managed because the interface status of the management address is down (because the physical connection is disconnected, the API Protocol cannot start ). To solve this problem, the loopback in

In the previous article we introduced the Ethernet 5 layer model, which I want to learn about the encapsulation and unpacking of Ethernet data, and how Ethernet data is transmitted. First, data encapsulation when our application uses TCP to transmit data, the data is fed into the protocol stack, then passes through each layer one by one, knowing that the final to
