Pkviz is a tool for plotting and cycling through and animating a series of network packets captured by tcpdump. What makes it unique is that the packets’ structure is visualized, not any labels and not time itself. Pkviz takes each byte in a packet and plots it out end-to-end, left-to-right, from the first byte to the last. How high the dot gets plotted depends on the value of the byte: bytes with a value of 0 are at the bottom and those which are 255 (0xff) – the maximum value of a byte – get plotted at the top. This might not be interesting for one packet, but that changes when you start looking at thousands of packets. Pkviz can cycle through thousands of packets in the set so you can see what happened on the wire.
TrafficMaker is a packet generator tool that allows you to create custom network packets and send them via any network interface. It can be used to generate junk/malformed random packets, STP, LACP, OAM, and LLDP layer 2 bridging/slow protocol packets, RIPv1, RIPv2, IGMPv1, IGMPv2, OSPF, IS-IS, EIGRP, and HSRP routing packets, SIP and RTP VOIP packets, ICMP, CDP and HSRP Cisco protocol packets, IPv4 TCP packets with various TCP flag options (SYN, ACK, Push, Reset, Urgent, Finish), IPv4 and IPv6 UDP packets, and RADIUS and Kerberos authentication packets. Inline context-specific per-page help is provided.
