Hi, my IPv6 dropped suddenly and now I cant get through to my POP anymore. I tried searching the FAQ for a cure but so far all I could come up with was something in my tcpdump output when I ping6 my POP: 08:55:15.427482 IP 80.223.145.56 > 62.78.96.38: 2001:14b8:14b:2:1::1 > 2001:14b8:100:55::1: icmp6: echo request seq 6 0x0000: 4500 007c 8012 4000 4029 39bb 50df 9138 E..|..@.@)9.P..8 0x0010: 3e4e 6026 6000 0000 0040 3a40 2001 14b8 >N`&`....@:@.... 0x0020: 014b 0002 0001 0000 0000 0001 2001 14b8 .K.............. 0x0030: 0100 0055 0000 0000 0000 0001 8000 4ef5 ...U..........N. 0x0040: 3518 0006 4391 0841 5285 0600 0809 0a0b 5...C..AR....... 0x0050: 0c0d 0e0f 1011 1213 1415 1617 1819 1a1b ................ 0x0060: 1c1d 1e1f 2021 2223 2425 2627 2829 2a2b .....!"#$%&'()*+ 0x0070: 2c2d 2e2f 3031 3233 3435 3637 ,-./01234567 08:55:15.457057 IP 62.78.96.38 > 80.223.145.56: icmp 132: 62.78.96.38 protocol 41 unreachable 0x0000: 45c0 0098 520b 0000 3a01 ad0e 3e4e 6026 E...R...:...>N`& 0x0010: 50df 9138 0302 62f7 0000 0000 4500 007c P..8..b.....E..| 0x0020: 8012 4000 3a29 3fbb 50df 9138 3e4e 6026 ..@.:)?.P..8>N`& 0x0030: 6000 0000 0040 3a40 2001 14b8 014b 0002 `....@:@.....K.. 0x0040: 0001 0000 0000 0001 2001 14b8 0100 0055 ...............U 0x0050: 0000 0000 0000 0001 8000 4ef5 3518 0006 ..........N.5... 0x0060: 4391 0841 5285 0600 0809 0a0b 0c0d 0e0f C..AR........... 0x0070: 1011 1213 1415 1617 1819 1a1b 1c1d 1e1f ................ 0x0080: 2021 2223 2425 2627 2829 2a2b 2c2d 2e2f .!"#$%&'()*+,-./ 0x0090: 3031 3233 3435 3637 01234567 This seems like there's a problem with protocol 41? Is it a problem with my connection or the POP's? My IPv4: 80.223.145.56 My IPv6: 2001:14b8:100:55::2 POP IPv4: 62.78.96.38 (fihel01.sixxs.net) POP IPv6: 2001:14b8:100:55::1 ping6 to my ipv6 endpoint works but ping6 2001:14b8:100:55::1 returns: alpha:~# ping6 2001:14b8:100:55::1 PING 2001:14b8:100:55::1(2001:14b8:100:55::1) 56 data bytes From ::1 icmp_seq=2 Destination unreachable: Address unreachable From ::1 icmp_seq=3 Destination unreachable: Address unreachable Some enlightening would be nice. -Matti
