Through the Linux network programming-the original socket programming, we know that we can get the link layer packets through the raw sockets and recvfrom (), what is the link Layer Packet we receive ? Link Layer envelope formatMAC head (wired LAN)Note : CRC, PAD can be ignored when group packageOne of the scenarios of a link-layer packet:unsigned char msg[1024] = {//--------------group mac--------------0xb8, 0x88, 0xe3, 0xe1, 0x10, 0xe6,//Dst_mac:b

Network Analyzer composition block diagramFigure 1 shows the internal block diagram of the network analyzer. To test the transmission/reflection characteristics of the tested parts, the network analyzer is included;1. Excitation s

Whether you are a server administrator, a network administrator, or a VMware administrator, you use a protocol analyzer, also known as a data packet analyzer or a "sniffer", as a common tool for analyzing network problems. These software applications can analyze network traf

For large networks, faults may be difficult to handle, so an effective performance and function testing tool is very convenient. In order to adapt to the current wireless network, the new generation of Wi-Fi wireless protocol analyzer brings new vigor to the network test. The transmission media of WLAN is electromagnetic waves, which are almost ubiquitous and hav

We can use the network protocol analyzer to observe the network protocol analysis. Here we will explain the network analyzer. The best way to analyze data packets transmitted over the network depends largely on the device you have

Protocol Analyzer is one of the most powerful tools in the network Administrator library. It can save the company a lot of time and money by turning problems that are difficult, time-consuming, annoying to CEOs and even having to restart all machines to be short-lived and easily reflected in weekly status reports. However, just like any other complex tool, it must be properly used to achieve maximum benefi

three entries (this is just an example of how to use this file) and enter the server's public and private IP space in the following format:x.x.x.x/x Public IP spacex.x.x.x/x Private IP spaceSave and exit.Using Brocontrol to manage Bro installationsManaging Bro requires the use of Brocontrol, which supports both interactive shell and command-line tools. Start the shell:#/usr/local/bro/bin/broctlTo use command-line tools, you simply pass parameters to the previous command, for example:#/USR/LOCAL

THGs is a powerful network performance analyzer that can be accessed locally or remotely controlled by Surveyor software for effective diagnosis, fault identification and monitoring of any full or half duplex 10 M/100 M/M Ethernet network provides necessary tools.
