summary: provides proxy tcp service for a host on an isolated network.
programmer: Carl Harris (firstname.lastname@example.org)
date: 22 Feb 94
This code implements a daemon process which listens for tcp connec-
tions on a specified port number. When a connection is established,
a child is forked to handle the new client. The child then estab-
lishes a tcp connection to a port on the isolated host. The child
then falls into a loop in which it writes data to the isolated host
for the client and vice-versa. Once a child has been forked, the
parent resumes listening for additional connections.
The name of the isolated host and the port to serve as proxy for,
as well as the port number the server listen on are specified as
command line arguments.
