Capsa

Capsa is an Ethernet packet sniffer (network analyzer or network sniffer) for network monitoring and troubleshooting purposes. It performs real-time packet capturing, 24/7 network monitoring, protocol analysis, packet decoding, and automatic diagnoses. Target uses include isolating/solving network problems, identifying network bottleneck and bandwidth use, and detecting network vulnerabilities.

Network administrators can directly monitor HTTP requests, E-mail messages, and DNS queries, as well as real-time activities and message details for four instant messengers: MSN, AIM, ICQ, and Yahoo! Messenger.

Capsa is designed to be used by both IT professionals and novice users. Problems are identified and solutions are suggested. The program includes tables and graphs, as well as statistics and reports. Capsa includes tools to create and replay packets, and ping and scan IPs and MACs across the LAN.

Capsa includes the ability to conduct drilldown analysis on a single workstation, protocol or packet. After locating a single item, it allows you to get dedicated information about that item.

Capsa runs under Windows 2000/XP/2003/Vista. A trial version is available.
