For link-local addresses you must specify interface you want to use them. Also, there's an iperf switch to understand ipv6 "-V". iperf -V -i1 -s iperf -V -i1 -c fe80::ff:fe00:0%wlan1 iperf -V -i1 -c fe80::ff:fe00:100%wlan0 Michał -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
