specter is a user-space logging facility for the
Linux netfilter system. It uses netfilter's ULOG
target to gather packets, and passes them to
attached plugins. Its features a flexible and
robust modularized structure, and is based on
ulogd, but has improved design and wider
functionality. It currently supports a basic set
of network protocols (IP, TCP. UDP, and HTTP) and
can save data as text or PCAP, or add it to MySQL
or PostgreSQL databases.
