mechanism of the network.In addition, the network traffic reflects the operation status of the network, is the key to determine whether the network operation is normal. If the network receives more traffic than its actual carrying capacity, it can cause network performance

TUN/TAP Virtual Network device provides the ability to send and receive network packets for user-space programs. He can be either a point-to-point device (TUN) or an Ethernet device (TAP). In fact, not only does Linux support TUN/TAP virtual

When QEMU is started, the tap virtual network card and qemutap virtual network card are inserted. 1. Use the brctl command to create a virtual bridge br0 Brctl addbr br0 Ifconfig br0 up // the preceding two commands are executed separately, leading to network disconnection. 2. Bind the virtual bridge br0 to the p

In the computer network, Tun and tap are virtual network devices in the operating system kernel. Different from the common hardware network card implementation of the device, these virtual network devices are all software implementation, and running on the operating system o

1. Create a virtual bridge with the Brctl command br0Brctl ADDBR Br0Ifconfig br0 up//Two commands above will cause network disconnection2. Bind the virtual bridge BR0 with the physical NIC Eth0Brctl addif br0 eth0Ifconfig eth0 0.0.0.0//bridge is similar to a switch, it can be considered that the eth0 is just a port on the switch, you can think of all packets from the eth0, but ultimately by the bridge to determine the flow of packets, so as long as th

When we use VMware virtualization software, we often find that they can all Virtualize a nic, which seems amazing. In fact, in Linux, there are two kinds of virtual backup, point-to-Point device in Tun. Tap indicates an Ethernet device. It is used as a virtual NIC Driver. Program Data receiving and sending does not directly deal with the real network card, but is transferred through the user State. In Linux

Some time ago, the virtual network card installation was required.ProgramSo in the website to collect some, find to find, did not see a separate installation, most of the said to install openvpn, and then only install the virtual network card of the tap-win32.
