ucspi-tcp

The ucspi-tcp distribution contains tcpserver and tcpclient, which are easy-to-use command-line tools for building TCP client-server applications. tcpserver waits for incoming connections and, for each connection, runs a program of your choice. tcpclient makes a TCP connection and runs a program of your choice. This package includes several sample clients built on top of tcpclient: who@, date@, finger@, http@, tcpcat, and mconnect. tcpserver and tcpclient conform to UCSPI, the UNIX Client-Server Program Interface, using the TCP protocol. UCSPI tools are available for several different networks.
