For instance, I'm on machine 2a01:678:1:443::443, and I do : $ traceroute6 -n 2a01:678:100:2:: traceroute6 to 2a01:678:100:2:: (2a01:678:100:2::) from 2a01:678:1:443::443, 64 hops max, 12 byte packets 1 2a01:678:1:443:: 0.636 ms 0.602 ms 0.525 ms 2 2a01:678:1:443:: 2999.665 ms !A 2999.636 ms !A 2999.680 ms !A 2a01:678:1:443:: is it's default gateway, and is also directly connected to 2a01:678:100:2::, but it does not seem to be able to contact it. If I log onto the gateway, and I : $ ping6 -c 1 2a01:678:100:2:: PING6(56=40+8+8 bytes) 2a01:678:100:: --> 2a01:678:100:2:: 16 bytes from 2a01:678:100:2::, icmp_seq=0 hlim=64 time=1.146 ms --- 2a01:678:100:2:: ping6 statistics --- 1 packets transmitted, 1 packets received, 0.0% packet loss round-trip min/avg/max/std-dev = 1.146/1.146/1.146/0.000 ms It works, and now, I can : $ traceroute6 -n 2a01:678:100:2:: traceroute6 to 2a01:678:100:2:: (2a01:678:100:2::) from 2a01:678:1:443::443, 64 hops max, 12 byte packets 1 2a01:678:1:443:: 0.647 ms 0.671 ms 0.417 ms 2 2a01:678:100:2:: 0.852 ms 0.790 ms 0.669 ms Maybe I'm doing something wrong, but, well, I can't seem to find ou what. 2a01:678:1:443::443 is a 7.0 2a01:678:1:443:: is a 6.2 2a01:678:100:2:: is a 6.0 Those are not up to date to the latest thing you can get, but they're production machines, and I'm not really willing to upgrade them unless I really need to :-) -- Mathieu Arnold --==========24C7F403A71FEEAD9299========== Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (Darwin) iEYEARECAAYFAkihP60ACgkQJqR8av5thQ88ZwCgmBVmDbQz5DfXtJQr3EhoQjiO 2q4An1mt0Em7cBfOEueELq7k4WARh6Fl =Z5dv -----END PGP SIGNATURE----- --==========24C7F403A71FEEAD9299==========--
