SoftPerfect Network Scanner

SoftPerfectNetworkScanner is a free multi-threaded IP, NetBIOS and SNMP scanner , has a beautiful interface and a variety of advanced features. It can also detect user-defined ports and report open ports, resolve host domain names and automatically detect your local IP range.

Dumb Monitor (also known as: Dumb Sniffer) is a free network software that uses the computer's network interface to capture data packets flowing through the local network.

Dumb monitors can be used to analyze current network traffic and identify potential problems in the network of concern. For example, suppose that a certain section of the network is not running very well, the sending of messages is slow, and we don't know where the problem lies. At this time, we can use a dumb monitor to make an accurate judgment of the problem. In a reasonable network, the existence of dumb monitors is of vital importance to system administrators. System administrators can use dumb monitors to diagnose a large number of invisible and ambiguous problems involving two or even multiple computers. Some of the abnormal communications even involve various protocols. With the help of the dumb monitor, the system administrator can easily determine how much traffic belongs to which network protocol, which host accounts for the main communication protocol, and most communication destinations. Which host is it, the number of bytes sent by the message, or the interval between message transmissions between hosts, etc. This information provides very valuable information for administrators to judge network problems and manage network areas.

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, email sniffing, file transfer sniffing, etc.), in a shared mode 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 in detail. This will facilitate network management friends to analyze network traffic and solve specific faults, and will also help other network security friends to do testing. The software utilizes multi-threading technology, so that the main program can perform real-time statistical analysis and process monitoring during sniffing, and can manually control the working status of each thread. The software runs quickly, accurately and efficiently
