Information:
Network-I is a network analyzer suite, comprised of a packet sniffer with a filtering language and a suite of tools to process the captured packets. The possibilities range from the straightforward display of packets in exhaustive detail, or alternatively, in a one-line summary mode, to measurement of traffic rates and reporting on packet retransmission and losses. It can also import and export capture files in tcpdump and snoop formats.
Additional Software Required:
RPM-based or Debian-based Linux with 2.4 kernel or better, or Solaris (2.6 or better)
