Stress Test a NIC
I need to find out if the NIC on my MP-RAS box is bad. Unfortunately just sending out a ping to the loop back is not going to cut it. I need to be able to send out packets of information for several minutes at a time. I can't seem to find a tool or command to do this. Is anyone aware of a way to do this?Smilie

What system?

You could udpcast if you can install it:

udp-sender --file=/dev/zero on one system, udp-receiver --file=/dev/null on another on the same subnet, hit enter, let them have at it. You'll hit close to the maximum utilization allowed by your bus and network and get information on lost packets and retries needed.

Or netcat, though that's more of a pain to get working right.
