What is CommView?
CommView is TamoSoft's Windows network monitor and packet analyzer for investigating traffic on a PC or LAN segment. Its connection list shows addresses, ports and sessions, while the packet view exposes protocol details for closer inspection. Use filtering, string or hexadecimal searches and TCP session reconstruction to narrow an investigation from a busy connection list to the packets involved.
Captured traffic can be saved or exchanged with other analysis tools through formats including Wireshark/Tcpdump and pcapng. Protocol-distribution charts, bandwidth statistics and configurable alarms provide other views of network activity. The included VoIP analyzer supports SIP and H.323 analysis; remote capture uses the separate optional CommView Remote Agent.
Capture visibility depends on where the monitoring computer sits in the network. Installing CommView on one switched-LAN computer does not by itself expose every other workstation's traffic: the publisher describes managed-switch port mirroring for directing selected traffic to a monitoring port. CommView is also a separate product from CommView for WiFi, despite its ability to monitor traffic through a Wi-Fi adapter.
The linked ZIP is the publisher's Windows evaluation package, listed as version 7.0 Build 798. The evaluation lasts 30 days; continued use requires a commercial license. The download check confirmed the file endpoint using HEAD only, not an installation or a functional test.
What it offers
- Inspect captured packets and protocol decodes, with support for over 100 protocols listed by the publisher.
- Reconstruct TCP sessions and search captured contents for text or hexadecimal data.
- Map packets to applications and inspect IP addresses, ports, sessions and connection statistics.
- Import and export capture formats including Wireshark/Tcpdump and pcapng.
- View protocol and bandwidth charts, configure event alarms and analyze SIP or H.323 VoIP traffic.
Good to know
- The evaluation is limited to 30 days; CommView is commercial software, not a permanently free analyzer.
- Visibility of other computers' traffic depends on network topology and capture placement; a switched LAN can require port mirroring.
- Remote capture through CommView Remote Agent requires a separate optional add-on. CommView for WiFi is a different product.
