Tunnel T24641 (AYIYA) not working
![[it]](/s/countries/it.gif) Shadow Hawkins on Monday, 01 February 2010 18:37:32
Hello,
I've been using tunnel T24641 for some time now. Around a week (I can't tell precisely) ago it suddenly stopped working. The computer is an Archlinux box.
Now aiccu says that it is connected, just like always, as you can see here:
[root@popper ~]# aiccu test
Tunnel Information for T24641:
POP Id : ittrn01
IPv6 Local : 2001:1418:100:31b::2/64
IPv6 Remote : 2001:1418:100:31b::1/64
Tunnel Type : ayiya
Adminstate : enabled
Userstate : enabled
and
[root@popper ~]# aiccu version
AICCU 2007.01.15-console-linux by Jeroen Massar
However, I get a 100% packet loss when I try to ping from this side of the tunnel to the rest of the world. I can ping myself with no problems.
I seem to have the exact problem described in this similar ticket.
some more additional output:
[root@popper ~]# traceroute6 2001:1418:100:31b::1
traceroute to 2001:1418:100:31b::1 (2001:1418:100:31b::1) from 2001:1418:100:31b::2, 30 hops max, 16 byte packets
1 * * *
2 * * *
3 * * *
4 * * *
5 * * *
6 * * *
7 * * *
...
and this is tcpdump when I ping6 www.sixxs.net
[root@popper temp]# tcpdump -Xns 1500 -i sixxs

I've already tried what is listed here FAQ but with no luck.
I'm on AYIYA, I'm synced to pool.ntp.org and there's no firewall in the way. I haven't changed the configuration, and it's the same one as when it was working.
State change: resolved
The state of this ticket has been changed to resolved
Tunnel T24641 (AYIYA) not working
Works now:
64 bytes from 2001:1418:100:31b::2: icmp_seq=1 ttl=64 time=12.3 ms
Still need to tackle that problem for the final solution, all in due time...
