(Softperfectnetworkscanner 5.04softperfectnetworkscanner (also known as dumb sniffer) is a free network software that uses the network interface of the computer to capture data packets flowing through the local network. Dumb monitor can be used to analyze the traffic in the current network and find out the potential problems in the concerned network. For example, if a certain segment of the network does not work well, the message is sent slowly, and we do not know where the problem lies, we can use the dumb monitor to make accurate problem judgment. In a reasonable network, the existence of dumb monitors is of great importance to system administrators. System administrators can diagnose a large number of invisible fuzzy problems through dumb monitors. These problems involve abnormal communication between two or more computers, and some even involve various protocols. With the help of dumb monitors, system administrators can easily determine how much traffic belongs to which network protocol Which host accounts for the main communication protocol, which host accounts for most communication destinations, the number of bytes sent by messages, or the message transmission interval of mutual hosts, etc. these information provide very valuable information for administrators to judge network problems and manage network areas. Dumb monitor is a network monitor with sniffing settings, statistical analysis, contract testing, process monitoring, data analysis, encoding conversion and other auxiliary functions (password sniffing, mail sniffing, file transfer sniffing, etc.). It can capture all TCP, UDP, ICMP and other data packets flowing through the machine in the shared LAN, and display the specific structure information and sensitive data of the captured IP packets in detail. Thus, it is convenient for network management friends to analyze network traffic and solve specific faults, and it is also helpful for other network security friends to do tests. Multithreading technology is used in the software, so that the main program can carry out real-time statistical analysis and process monitoring when sniffing, and can manually control the working state of each thread. The software runs quickly, accurately and efficiently.
