KSnuffle is a network packet sniffer for KDE. It supports multiple concurrent sniffers, packet filtering (aka tcpdump), event triggers and commands, text and binary logging (and replay), remote sniffing (via a demon process), and dynamically loadable plugins. Network traffic is displayed graphically and in detail; supplied plugins summarise traffic by direction (incoming, outgoing), source, and destination.
