CommView is a program for monitoring network activity capable of capturing and analyzing packets on any Ethernet network. It gathers information about data flowing on a LAN and decodes the analyzed data.

You can see the list of network connections, vital IP statistics, and examine individual packets. IP packets are decoded down to the lowest layer with full analysis of the main IP protocols: TCP, UDP, and ICMP.

Full access to raw data is also provided. Captured packets can be saved to log files for future analysis. A flexible system of filters makes it possible to drop packets you don't need or capture only those packets that you wish to capture.

Here are some key features of "CommView":

· View detailed IP connections statistics: IP addresses, ports, sessions, etc.
· Reconstruct TCP sessions.
· View protocols distribution, bandwidth utilization, and network nodes charts and tables.
· Generate traffic reports in real time.
· Browse captured and decoded packets in real time.
· Search for strings or hex data in captured packet contents.
· Log individual or all packets to files.
· Load and view capture files offline.
· Import and export packets in Sniffer®, EtherPeek™, AiroPeek™, Observer®, NetMon, Tcpdump, hex, and text formats.
· Configure alarms that can notify you about important events, such as suspicious packets, high bandwidth utilization, unknown addresses, etc.
· Create your own plug-ins for decoding any protocol.
· Exchange data with your application over TCP/IP.
· Export any IP address to SmartWhois for quick, easy lookup.
· Capture loopback traffic (a new, unique feature in version 4.1).
