|
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.
