Folks
I have a server and client perl programs written using IO::Socket. The server looks just fine (I think). But the client opens a connection to the server. It sends the message for the first time and receives it successfully. The second time, the client shows an empty message and the third time it fails with "cannot determine peer address". If I create a new socket everytime, that is, if I do my $remote = IO::Socket::INET->new() inside the loop in the client code, the code works just fine but I dont want to open a new connection everytime. Can you please tell me what should I do to open a connection to the server once and use it for n times.
Thanks for your help
CLIENT CODE:
use strict;
use IO::Socket;
my $remote = IO::Socket::INET->new(
Proto => 'tcp', # protocol
PeerAddr=> '127.0.0.1', # Address of server
PeerPort=> "1426", # port of server
Timeout => 90
) or die "$!";
$remote->autoflush(1);
for (my $i = 0; $i < 100 ; $i++)
{
$remote->send("Test \n"); # Send to Server
my $line ;
$remote->recv($line,256); # Receive echo from server
print $line. "\n";
}
close $remote; # Close socket
SERVER CODE:
use IO::Socket qw(:DEFAULT :crlf);
use IO::File;
use constant PIDFILE => "/tmp/prefork.pid";
use constant PREFORK_CHILDREN => 3;
my $port = shift || 1426;
my $socket = IO::Socket::INET->new(
Proto => 'tcp',
LocalPort => $port,
Listen => 5,
Reuse => SO_REUSEADDR,
Type => SOCK_STREAM
) or die "Can't create listen socket: $!";
# create PID file, initialize logging, and go into background
#init_server(PIDFILE);
make_new_child() for (1..PREFORK_CHILDREN);
exit 0;
sub make_new_child {
#my $child = launch_child();
my $child = fork;
return if $child;
do_child($socket); # child handles incoming connections
exit 0;
}
sub do_child {
my $socket = shift;
while (1) {
local $/ = "\n";
next unless my $c = $socket->accept;
handle_connection($c);
close $c;
}
close $socket;
}
sub handle_connection
{
my $x = shift;
my $sz = <$x>;
print $x "Testing\n";
}
