Can you do a 'ping6 marge.sylvia.test' ? > (cant give the original error now; i am > not physically there at the moment but will be tomorrow) > when i start the client with "iperf -c 2001:xxxxx -V" i get the message > unknown host Ordering of arguments has some significance, use the -V always as the first option, eg: $ iperf -c 2001:db8:1:1:210:dcff:fe20:7c7c -V multicast ttl failed: Invalid argument connect failed: Connection refused <SNIP> Now we get a multicast error!? $ iperf -V -c 2001:db8:1:1:210:dcff:fe20:7c7c connect failed: Connection refused <SNIP> Now we don't get that warning. Thus option handling seems to be a bit odd. > any ideas? someone out there who tried that yet??
