iperf might be able to do what you need and there are Windows builds available, but I'm not sure if it has a mode where it's not flooding the network trying to test maximum speed. Is there a reason that standard ICMP pings aren't appropriate if you just want packet loss info? Obviously every platform worth using has ping built in. ---------- Sean Harlow sean@seanharlow.info On Dec 22, 2011, at 2:28 PM, Jay Nakamura wrote:
The goal of what I am doing is to test some network convergence impact in a lab with two PCs with windows (Can't run Linux, it would be easier if I could) and switches and/or routers in between.
So, I thought there must be some simple utility out there that can just start spewing out UDP packets to the other side at a certain time interval and I can look at packet loss via what arrives on the other side with wireshark on the PC.
I found hping but it seems to be outdated and I can't get it to work on my windows boxes.
Anyone have any suggestions?
