YpFw is a frontend to ipfw and dummynet. It was developed to ease the setting and managing of ipfw rules and dummynet pipes on FreeBSD. It features a curses text interface, which allows the user to add/delete rules, update/clear rules counters, and add/delete/configure pipes. It is not meant as a replacement to ipfw; the user will need to understand ipfw and dummynet rules and syntax.
Amberfish is a general purpose text/XML retrieval utility. It features indexing of both free text and nested fields, built-in support for XML documents, structured queries allowing generalized field/tag paths, hierarchical result sets, automatic searching across multiple databases, efficient indexing, and relatively low memory requirements.
