Colasoft Capsa vs termshark

Colasoft Capsa is a Windows network analyzer for monitoring, analyzing and troubleshooting wired and wireless networks. The Enterprise edition captures packets in real time from local networks and can save transmitted data. It analyzes more than 1,800 protocols and sub-protocols, including VoIP, and displays packet details in Hex, ASCII and EBCDIC. Capsa can diagnose network problems and suggest solutions, monitor conversations, reconstruct packet streams and generate reports for selected items, the whole network or a particular network group. Its security analysis detects DoS and DDoS attacks, worm activity, ARP attacks, TCP port scans and suspicious conversations in real time. Users can set email or sound alerts and schedule capture once, daily or weekly. Capsa Free monitors up to 10 IP addresses, ends sessions after four hours and lacks WiFi connection monitoring. Professional is listed at $695, paid once for a single-seat perpetual license, one machine and one year of maintenance. Enterprise is $1,295, paid once and has a 30-day trial.

termshark is a terminal interface for tshark, inspired by Wireshark, for inspecting packet captures and network traffic. It can read pcap files or sniff live interfaces when tshark is permitted, including on a remote machine where a capture need not be copied to a desktop. Users can apply Wireshark display filters, group conversations by protocol, and reassemble TCP and UDP streams. Packet search covers packet lists, structures and bytes, using text, regular expressions, hexadecimal input or display filters. The guide also describes importing a Wireshark column set when the configuration can be found, and transferring the current capture with Magic Wormhole. The project lists Linux, macOS, BSD variants, Android through Termux and Windows. It is free and MIT-licensed, and the project says its Go implementation builds as one executable on each platform. Packet analysis requires tshark 1.10.2 or higher in the user's PATH. The project notes that some tshark features are not yet exposed by termshark; the latest listed release is v2.4.0, dated July 11, 2022.
