I've got juno-z.101f.c to send 500,000 pps at 300+mbit on our dual p3
1.26 ghz routers.. I can't even send 50mbit of this though one of my
routers
Without it using 100% of both cpus because of the route cache.. It goes
up to 500,000 entries if I let it and it adds 80,000 new entries per
second and they are all cache misses.. I'd be glad to show you the setup
sometime :) I showed it to jamal and we tested some stuff.

OK so let's try this.. If you can show me a linux router can can route

100mbps or more of juno-z.101f.c attack without dropping packets I 
will be thoroughly impressed  :)

I am willing to test out any code/patches and settings that you can 
think of and post some results..

I'll see if I can set up a test bed this week.  I think we should
already be able to do close to this, but I'll let the numbers will do
the talking. :)

In the tests I've been doing so far, I've been dropping responses (in
the INPUT chain), so I haven't been testing the forwarding through of
packets (though it is testing the routing input).  I'll see if I can set
up a router, target, and DoS box.

I haven't been able to get juno-z.101f.c to saturate 100 Mbit/sec
outgoing, but I've only tried it on eepro100 boxes.  Has anybody got it
to send more?  Mmm, need more tg3 cards...
