Thanks to all who gave pointers. However none of these tools accept a network 
address for target. So I have to execute the programs once for each target 
address. I wanted to check the multipath routing code and so required that 
the packets have different destination IP addresses. So I wrote a small 
program to generate packets to a range of addresses.

Thanks again,
Ashok
