Introduction


What is VisualSniffer?

VisualSniffer is a powerful packet capture tool and protocol analyzer based on Windows system. IP packets are organized based on their source and destination addresses and TCP/IP packets are further grouped into connections. You can also set up filters to receive only subsets of the network traffic. VisualSniffer decodes TCP, UDP and ICMP packets down to the lowest layer, and provides raw packet data in Hex format and syntax highlighting viewer. VisualSniffer can also analyze network traffic for matches against a user defined rule set and give warning messages based upon what it sees. VisualSniffer can save captured packets into a log file with format of "libpcap", which is a standard used by a lot of network tools. It can also load data from a "libpcap" file.
