Well, as Stef said, anyway that's why I need (because UDP won't ask for
replies)
However, the problem I encountered with MGEN is that it does not accept
to blindly send udp packets: it first try to resolve the address of the
remote station (which in my case does not exist).
As I was away, I've just started again to look seriously at the problem
so I still have to try Bartek and Ashok solutions.
Up to know, I've discarded:
   - linux's kernel traffic generator: it bypasses traffic control
   - ttcp because TCP does not suit in my case
   - tg: because of an installation error :) Too lazy to even check in
the documentation if it worths tring to install it.
   - mgen: as I said above, it doesn't accept to blindly sens udp
packets but first try to resolve the remote address
   - ping -f: flooding is ok, but I cannot modify parameters (ports,
adresses) as I'd like to (well, I could start many pings with different
parameters at once) and it needs acknowledgements.

And I still have to try:
   - udpgen: I have to modify the makefile to install it
   - hping2
   - spak

Tahnk you guys anyway.
By the way, Ashok you may find something that fits your needs in that list.

Thanks to all who gave pointers. However none of these tools accept a net=
work=20
address for target. So I have to execute the programs once for each targe=
t=20
address. I wanted to check the multipath routing code and so required tha=
t=20
the packets have different destination IP addresses. So I wrote a small=20
program to generate packets to a range of addresses.

Thanks again,
Ashok
