Description-en: command-line tools for building TCP client-server applications
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.
