(Dumb Monitor is a network monitor with sniffing settings, statistical analysis, packet testing, process monitoring, data analysis, code 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 local area network, and display the specific structure information and sensitive data of the captured IP packets. Then it is convenient for the network management brothers to analyze network traffic and manage specific faults, and it is also helpful for other network security brothers to test. The multi-thread technology is used in the software, so that the main program can perform real-time statistical analysis and process monitoring when sniffing, and can manually control the working status of each thread. The software runs fast, precise and efficient.)
