SiLK, the System for Internet-Level Knowledge, is a collection of
traffic analysis tools developed by the CERT Network Situational
Awareness Team (CERT NetSA) to facilitate security analysis of large
networks. The SiLK tool suite supports the efficient collection,
storage and analysis of network flow data, enabling network security
analysts to rapidly query large historical traffic data sets. SiLK is
ideally suited for analyzing traffic on the backbone or border of a
large, distributed enterprise or mid-sized ISP.
The silk-rwsender package contains a program (rwsender) which
transmits files over the network to one or more rwreceiver programs.
rwsender-rwreceiver pairs are used to move files from a machine
running flowcap and one running rwflowpack, or from the rwflowpack
machine to machine(s) running rwflowappend.
