Urklipp från internet. Detta sätter upp en socket utan inblandning av xinetd.

A Simple Server

#! /usr/bin/perl -w
# server0.pl
#--------------------

use strict;
use Socket;

# use port 7890 as default
my $port = shift || 7890;
my $proto = getprotobyname('tcp');

# create a socket, make it reusable
socket(SERVER, PF_INET, SOCK_STREAM, $proto) or die "socket: $!";
setsockopt(SERVER, SOL_SOCKET, SO_REUSEADDR, 1) or die "setsock: $!";

# grab a port on this machine
my $paddr = sockaddr_in($port, INADDR_ANY);

# bind to a port, then listen
bind(SERVER, $paddr) or die "bind: $!";
listen(SERVER, SOMAXCONN) or die "listen: $!";
print "SERVER started on port $port ";

# accepting a connection
my $client_addr;
while ($client_addr = accept(CLIENT, SERVER))
{
# find out who connected
my ($client_port, $client_ip) = sockaddr_in($client_addr);
my $client_ipnum = inet_ntoa($client_ip);
my $client_host = gethostbyaddr($client_ip, AF_INET);
# print who has connected
print "got a connection from: $client_host","[$client_ipnum] ";
# send them a message, close connection
print CLIENT "Smile from the server";
close CLIENT;
}

A Simple Client

#! /usr/bin/perl -w
# client1.pl - a simple client
#----------------

use strict;
use Socket;

# initialize host and port
my $host = shift || 'localhost';
my $port = shift || 7890;
my $proto = getprotobyname('tcp');

# get the port address
my $iaddr = inet_aton($host);
my $paddr = sockaddr_in($port, $iaddr);
# create the socket, connect to the port
socket(SOCKET, PF_INET, SOCK_STREAM, $proto)
or die "socket: $!";
connect(SOCKET, $paddr) or die "connect: $!";

my $line;
while ($line = )
{
print $line;
}
close SOCKET or die "close: $!";
