Libsmi is a C library that allows network management applications to access SMI MIB module information through a well-defined API that hides the nasty details of locating and parsing SMIv1/v2 MIB modules. Libsmi supports exact and iterative retrieval functions for all major SMIv1, SMIv2, and SMIng constructs. Some tools allow SMI module queries, checks, dumps, extraction, and various conversions and code generation.
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.
