Client Server Connection through sockets issue.
|
Can't Post
|
|
I am new into sockets programming through perl:
I have the following server.pl
#!C:\Perl\bin\perl
use strict;
use Socket;
print "Content-type:text/html\n\n";
print "<html>\n";
print "<ul>";
# use port 7890 as default
my $port = shift || 7890;
my $proto = getprotobyname('tcp');
my $paddr = sockaddr_in($port, INADDR_ANY);
# create a socket, make it reusable
socket(SOCKET, PF_INET, SOCK_STREAM, $proto)
or die "Can't open socket $!\n";
setsockopt(SOCKET, SOL_SOCKET, SO_REUSEADDR, 1)
or die "Can't set socket option to SO_REUSEADDR $!\n";
# bind to a port, then listen
bind( SOCKET, $paddr)
or die "Can't bind to port $port! \n";
listen(SOCKET, 5) or die "listen: $!";
print "<li>SERVER started on port $port\n";
# accepting a connection
my $client_addr;
while ($client_addr = accept(NET_SOCKET, SOCKET)) {
# send them a message, close connection
print NEW_SOCKET "Smile from the server";
close NEW_SOCKET;
}
print "</ul>";
print "</html>\n";
and the following client.pl
#!C:\Perl\bin\perl
use strict;
use Socket;
print "Content-type:text/html\n\n";
print "<html>\n";
print "<ul>";
# initialize host and port
my $host = shift || 'localhost';
my $port = shift || 7890;
my $server = "localhost";
my $iaddr = inet_aton($host);
my $paddr = sockaddr_in($port, $iaddr);
# create the socket, connect to the port
socket(SOCKET,PF_INET,SOCK_STREAM,(getprotobyname('tcp')))
or die "Can't create a socket $!\n";
connect( SOCKET, $paddr)
or die "Can't connect to port $port! \n";
my $line;
while ($line = <SOCKET>) {
print "$line\n";
}
close SOCKET or die "close: $!";
print "</ul>";
print "</html>\n";
But I am unable to connect the client to the server. Do please let me know the areas I need to look into.
Thanks & Regards,
Manish.
