Port Mirroring is a very important function in network devices and plays a role in management and monitoring. It also plays a role in device security, monitor the packet information of an important network device to prevent any adverse network security events. Port images ar

[Reading Notes] iOS network-use Game Kit to implement inter-device communication and ioskit Apple's Game Kit framework enables communication between devices without a network, including the absence of cellular services, wi-Fi infrastructure and LAN or Internet access are unavailable. For example, in the depths of the jungle, on a highway or in the basement of a b

Virtual machine copies are often encountered during the entire virtual machine, but the network configuration will encounter errors after the copy Service network Restart when starting the network prompts the following error: Device does not seem to is present resolution Steps 1, ifconfig-a view the current

Broadband access networks are still commonly used. So I studied the broadband access network device optimization solution. Here I will share it with you and hope it will be useful to you. After several years of broadband development, the broadband business revenue is increasing year by year, and fixed network operators also regard the broadband business as one of

Note: This article describes the Xen semi-virtualized NIC vif mechanism, carding function.The Xen block device driver uses the mechanism of the Xen IO ring.The role of Xen Hyprevisor is to provide a layer of protection between the virtual machine and the IO device, so that the data transfer mechanism is to move between the systems while bringing in relatively small overhead. The two primary data transfer me

The Fedora developer MattDomsch said that starting from Fedora15, the conventional ethX method will no longer be used to name the ethernet card device. A new network device naming system ConsistentNetworkDeviceNaming (CNDN) is being developed for Fedora15 ). In Linux, ethX is often used to name Ethernet devices. Generally, a desktop computer has only one Ethernet

Problem: After Ubuntu is upgraded, It is found in NetworkManager that only wireless network connections are allowed. The location of the wired eth0 shows "device not managed" It should be that networlmanager does not manage wired connections. Google to the solution, the specific principle is not very clear, just as prompted, can solve the problem, archive for future viewing Ubuntu 9.04 "wired

Method One 1, if we find "computer" on the desktop to open it into; 2, on the navigation to find "Uninstall or change program" click it open; 3, find the driver to remove and click "Uninstall" on the right, follow the on-screen instructions to complete the uninstall. Note: Atheros Wireless network card is usually the name with Atheros WLAN Client, Broadcom wireless network

In the telecommunication network management system, the real-time display of the equipment status information is very important, usually mount a bunch of icons to display the status or alarm information, the limited information of the icons, sometimes need more detailed panels, even in the form of a chart, this article will combine the needs of recent customers, using the Qunee1.6 beta version, Realize real-time display of

At present, China's route switch equipment is developing very rapidly, and it is also more important in the development of the network, it also promotes the upgrade of routing technology. Traditional route switches are mainly used for Fast Packet forwarding, with emphasis on forwarding performance. With the wide interconnection of LAN and the openness of TCP/IP protocol, network security becomes a prominent

Layers of network equipment: network devices have repeaters, bridges, routers, gateways, and so on. Repeater (Repeater) repeater is the simplest device for LAN interconnection, which works at the physical layer of the OSI architecture, receives and recognizes network signals, and then regenerates the signals and sends

". C:windowssystem32> Netsh wlan start hostednetwork The hosting network has started. At this point, other notebooks or smartphones can search the Wifi,ssid for Test-wlan, the key is test123456, connect and surf the Internet. "Problem Failure" You often encounter a failure when you restart your computer and then reopen the virtual WiFi. Show: C:windowssystem32> Netsh wlan start hostednetwork Unable to start the hosting

restarted, other devices do not receive the restart command. But the solution is a bit improper, z-stack send data is asynchronous, that is, after the Af_senddata function call is completed and not sent out but to the next layer to continue packaging after the final to send out, so should delay, but not using blocking delay, stay in the current state, Causes the packet to not be sent out. My solution is after the Af_senddata,using the Osal_start_timerex timer, the timer will generate an event y
