i think i have made it out..
just check this code..

<title>Check the Open ports</title>
<pre> <font size=3><b>Hai
Using this application u can check the ports that are opened in the ip address.
If no port is mentioned it will check for the default ports..
<a href="http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers" target="_blank">For list of TCP/UDP ports</a>
Common Ports Used are
FTP 21
SSH 22
Telnet 23
SMTP 25
Web 80
Pop 3 110
IMAP 143
Other Applications
Remote Desktop 3389
PC Anywhere 5631</b></font>
