iPerf UDP
I set out to test the connection between my house and my development workstation, using VOIP-like settings, and IPv6, just to say I’d done it.
client side:
$ iperf -c dev.ciscodude.net -V -u -b 64k -l 160
------------------------------------------------------------
Client connecting to dev.ciscodude.net, UDP port 5001
Sending 160 byte datagrams
UDP buffer size: 160 KByte (default)
