+ longDescription = ''
+ 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.
