Just a couple of things off the top of my head. I've once did this in Java but I did it slightly different. First you should know that Java does not support ICMP. I had to implement my ping packet as a UDP packet. The second thing is that you don't really want to ping port 53. Go for port 7 which is the echo port which was designed to echo stuff back at you anyway. What happens when you don't have a daemon listening on port 53 ? You will not get a reply back and you will be thinking that the machine is dead even though its up it just doesn't know what to do with your packet.
