Sockets Problem (Networking)
|
Can't Post
|
|
I am trying to make a program which will try and connect to a remote computer or server, I can successfully create a new socket for the client, but when the client tries to connect an error returns "Connection Refused". My program code is display on this post, any ideas anyone?
I am quite new to networking in perl, and the program I am trying to create is a CGI script to run on a server, if the user can successfully connect to the server I want to print "Connection Successful" if a server is unavailable to connect to I want to print "Connection Unsuccessful".
Any help would be most helpful.
Code:
#!/usr/bin/perl
use Socket;
print "Content-type: text/html\n\n";
my ($server, $port, $proto, $serveraddr);
$servername = "www.supersitespro.com";
$port = 2001;
$port = getservbyname($port, 'tcp');
$server = gethostbyname($servername) || dienice("Unable to get host by name : $!");
$proto = getprotobyname('tcp');
$serveraddr = sockaddr_in($port, $server);
if (socket(SOCK, PF_INET, SOCK_STREAM, $proto)){
print "Socket OK<br>";
}
else{
print "Socket Failed<br>";
}
connect(SOCK, $serveraddr) || print "Connection Failed : $!<br>";
close(SOCK);
sub dienice{
my($msg) = @_;
print "$msg";
exit;
}
Many Regards,
