Decode tcpdump(1) output

tcpshow reads a tcpdump1 savefile and provides a reasonably complete decode of Ethernet, IP, ICMP, UDP and TCP headers. Boolean expressions may also be specified for packet selection. Data within the packets are displayed in ASCII.

tcpshow’s output is simular to Sun Solaris’s snoop1M command for network packet capture and inspection.
