since a long time I have a tunnel to my system. Now for a few days my tunnels is reporting to be down. If I do a traceroute form the web-site of sixxs there is no loss to my IP address (2001:960:2:d8::2), only some loss to the one before. If I do a ping6 from a server at my provider where I have login and ipv6 support I get a full ping response (see below) Can somebody help me founding out why my tunnel is reporting unavailble and why I get the responce from the other server (outside the sixxs domain) and from the traceroute of the sixxs website? Kindly yours, Erik-jan Ping trace form xs6.xs4all.nl jemrogge@xs6:~% ping6 -c3 2001:960:2:d8::2 PING6(56=40+8+8 bytes) 2001:888:0:1::666 --> 2001:960:2:d8::2 16 bytes from 2001:960:2:d8::2, icmp_seq=0 hlim=59 time=11.320 ms 16 bytes from 2001:960:2:d8::2, icmp_seq=1 hlim=59 time=10.700 ms 16 bytes from 2001:960:2:d8::2, icmp_seq=2 hlim=59 time=11.344 ms --- 2001:960:2:d8::2 ping6 statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max/std-dev = 10.700/11.121/11.344/0.298 ms traceroute from the sixxs ws: IPv6 traceroute IPv6 traceroute from nlams01.sixxs.net @ Concepts ICT BV, AS12871 to 2001:960:2:d8::2 : Hop Node Loss% Sent Last Avg Best Worst StDev ASN Organisation 1. 2001:838:2:1::1 0.0% 5 0.5 0.5 0.5 0.5 0.0 12871 Concepts ICT 2. 2001:838:0:10::1 0.0% 5 2.5 2.6 2.5 2.7 0.1 12871 Concepts ICT 3. 2001:7f8:1::a501:2634:1 0.0% 5 2.5 2.5 2.5 2.6 0.1 amsix.pe01.sara.ipv6.network.scarlet.nl. 4. 2001:960:226::134 0.0% 5 2.8 2.9 2.8 3.2 0.1 12634 Cybercomm ge-1-3-0.pe02.intx.ipv6.network.scarlet.nl. 5. ??? 100.0 5 0.0 0.0 0.0 0.0 0.0 6. 2001:960:2:d8::2 0.0% 5 13.0 13.4 13.0 13.9 0.4 12634 Scarlet Internet B.V. cl-217.ams-04.nl.sixxs.net.
