Samplicator - Send copies of (UDP) datagrams to multiple receivers, with optional sampling and spoofing

This small program receives UDP datagrams on a given port, and resends those datagrams to a specified set of receivers. In addition, a sampling divisor N may be specified individually for each receiver, which will then only receive one in N of the received packets. INSTALLATION This distribution...
