I have following requirement.
1)There are three entities in the program. node A (Linux box),B(Windows Server) and C(Any node). Node C is unreachable from Node A directly. Node B is a Windows server, where a perl script has to manage the transfer of ping request from a perl script in node A node C and then return the message (pass/fail) to node A.
2) I am ready with a perl Server script in Windows server, which accepts ping request from client script and pings node C successfully. Using IO::Socket module.
Requirement:
there can be N number of client like node A which will be pinging node C through script running in Node B. Script in Node B should accept the IP address from Client A, Ping the node specified and send the result to that client. For that I can't figure out how in Node B can I determine the port and Ip address of node running client A kind of application. So that I can send the result to client A and client A displays the result and dies
MyServer.pl 
#!/usr/bin/perl
use IO::Socket;
use Net::Ping;
$sock = new IO::Socket::INET (LocalHost => 'xxx.xxx.xxx.xxx', LocalPor
+t => 9321, Proto => 'tcp', Listen => 5, Reuse => 1 );
die "Socket could not be created. Reason: $!" unless $sock;
$reach = Net::Ping->new($ > ? "tcp": "icmp");
(defined $reach) or die "Couldn't create Net::Ping object: $!\n";
while ($new_sock = $sock->accept()) {
while (defined ($buf = <$new_sock>)) {
print $buf;
$host = (split(/:/,$buf))1;
print "$host";
if($reach->ping("$host"))
{
print "host is reachable";
}
else
{
print "host is unreachable";
}
}
}#end of 1st while loop
close ($sock);
