Use ping6? > yes apart from ping6, you can use: 1. wireshark/ethereal for seeing ND messages on the wire 2. if possible, setup ISATAP in your lab-network. ubuntu does have a isatapd, so should other distributions. 3. once you have (2) setup, update your resolver to do quad-A queries by default i.e. 'option inet6'. if you use google's DNS, you should be able to see dancing turtle at kame.org for example, i have the following is0 Link encap:IPv6-in-IPv4 inet6 addr: 2001:420:5401:1:200:5efe:4067:9c63/64 Scope:Global inet6 addr: fe80::200:5efe:4067:9c63/64 Scope:Link UP RUNNING NOARP MTU:1280 Metric:1 RX packets:1352 errors:0 dropped:0 overruns:0 frame:0 TX packets:872 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1575341 (1.5 MB) TX bytes:72571 (72.5 KB)
