Hey, all. We're trying to track down some UDP fragmentation issues, and
I'm trying to fully grasp exactly what goes on. The tool I'm using is
"iperf." My first confusion is that when I point iperf (client) to a
host behind a floating IP, that simply doesn't work. Any ideas what the
issue is, and how to get around it?
Next up is this that when I have to VMs talk to each other -- on the
same subnet, using "iperf -c 172.23.244.169 -u -b 100m" -- I wind up
with this:
[ 3] Sent 85471 datagrams
[ 3] WARNING: did not receive ack of last datagram after 10 tries.
When I go from physical machine to physical machine, it works great,
even though a few datagrams are received out-of-order. But a flat-out
missing packet does sound a bit like the issue I'm having.
-----------------------
Additionally, I'd really like a tool that would allow me to set packet
size for UDP tests; I've poked around, but haven't really found
anything. If anyone has a suggestion, I'm all ears.
Thanks!
-Ken
