Thank you thanos1983, i just picked up 127.0.0.1 and port 80 as an example in my question, my intention is to find out better way to test if an established connective is still active or not before sending data or to avoid opening another instance of same connection, if i can be able to call 

 return (0) unless ($sock->connected()); 
return (0) unless (getpeername($sock));

[download]

unfortunately i cant call to them without socket or is there a better way
