Description:
UNIX-domain socket client-server command-line tools
unixclient and unixserver are command-line tools for building UNIX domain client-server applications. unixclient connects to a UNIX domain socket and runs a program of your choice. unixserver creates a UNIX domain socket, waits for incoming connections and, for each connection, runs a program of your choice. . unixclient and unixserver conform to UCSPI, the UNIX Client-Server Program Interface, using UNIX domain sockets. UCSPI tools are available for several different networks. . See http://cr.yp.to/proto/ucspi.txt for more information on UCSPI. See http://untroubled.org/ucspi-unix/ for recent informations.
