I'm looking for something to stress-test the network connection between two boxes - specifically to check for an intermittent NIC dropout on one of them. I started with flood-ping, but a) this doesnt seem to really flood - it tops out at something like 250 packets/sec whatever the packet size, and b) I dont know if it compares sent data with received data. I would really like to have something which can send randomised packet lengths of randomised data at randomised intervals, and checks that received data matches sent data. Any suggestions? Cheers, Terry.
