Perl Script: Simple Network Programming (Client - Server Application)

A network socket is an endpoint of an inter-process communication flow across a computer network. Today, most communication between computers is based on the Internet Protocol; therefore most network sockets are Internet sockets.

In Perl, IO::Socket::INET provides an object interface to creating and using sockets in the AF_INET domain. It is built upon the IO::Socket interface and inherits all the methods defined by IO::Socket.

Below is a simple server created using Perl IO::Socket::INET module

Source: server.pl
#!/usr/bin/perl

use IO::Socket::INET;

$socket = new IO::Socket::INET (
    LocalHost => '127.0.0.1',
    LocalPort => '40000',
    Proto => 'tcp',
    Listen => 10,
    Reuse => 1
) or die "Oops: $! \n";
