Description:
command-line tools for building TCP client-server applications (IPv6)
ucspi-tcp-ipv6 is the ucspi-tcp package with IPv6 support added. . tcpserver waits for incoming connections and, for each connection, runs a program of your choice. Your program receives environment variables showing the local and remote host names, IP addresses, and port numbers. . tcpserver offers a concurrency limit to protect you from running out of processes and memory. When you are handling 40 (by default) simultaneous connections, tcpserver smoothly defers acceptance of new connections. . tcpserver also provides TCP access control features, similar to tcp-wrappers/tcpd's hosts.allow but much faster. Its access control rules are compiled into a hashed format with cdb, so it can easily deal with thousands of different hosts. . This package includes a recordio tool that monitors all the input and output of a server. . tcpclient makes a TCP connection and runs a program of your choice. It sets up the same environment variables as tcpserver. . 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.
