Detecting computers on network

[Sandeep Arya]

Thanks linuxfreak and sybren  for positive comments

My application will be running on Linux.
How to send ICMP ECHO as broadcast packets. I do not know this. Please tell 
me how to?

Sybren.. Does nmap is available on every systems? I tried on my linux fc4 
machine in user previleage. it was not working. Does this just belongs to 
superuser...

Is there any other way ? Can just socket.connect or sendto help me? I.E.

Won't work on all boxes. Windows boxes ignore broadcast pings, for
example.

I'd go for a call to "nmap -sP" instead, and filter it's output.
