[Linux] Destination unreachable: Address unreachable
![[es]](/s/countries/es.gif) Shadow Hawkins on Saturday, 08 May 2004 13:21:50
My tunnel isn't working, and I don't know why. this is the result of a ping to my gateway:
PING 2001:b18:2000:12::1(2001:b18:2000:12::1) from 2001:b18:2000:12::2 : 56 data bytes
From ::1 icmp_seq=2 Destination unreachable: Address unreachable
From ::1 icmp_seq=3 Destination unreachable: Address unreachable
From ::1 icmp_seq=4 Destination unreachable: Address unreachable
(...)
this is my heartbeat.conf:
os "linux"
ipv4_interface "eth0"
ipv4_pop "ptlis01.sixxs.net"
hb_behindnat 1
ipv6_interface "sixxs"
ipv6_pop "2001:b18:2000:12::1"
ipv6_local "2001:b18:2000:12::2"
ipv6_prefixlen 64
hb_password "*********"
hb_sendinterval 60
hb_timeout 300
routing table:

::/0 2001:b18:2000:12::1 UG 1024 0 0 sixxs
My tunnel script:
ip tunnel add sixxs mode sit local 192.168.1.2 remote 81.92.202.9
ip link set sixxs up
ip link set mtu 1280 dev sixxs
ip tunnel change sixxs ttl 64
ip -6 addr add 2001:b18:2000:12::2/64 dev sixxs
ip -6 route add default via 2001:b18:2000:12::1 dev sixxs
My NAT is forwarding the proto-41 to 192.168.1.2 (my endpoint).
I have the clock synchronized:
#ntptrace hora.rediris.es
hora.rediris.es: stratum 1, offset 0.006668, synch distance 0.00189, refid 'GPS'
My gw not respond to pings:
#tcpdump -i sixxs
tcpdump: WARNING: sixxs: no IPv4 address assigned
tcpdump: listening on sixxs
13:17:48.870117 cl-19.lis-01.pt.sixxs.net > gw-19.lis-01.pt.sixxs.net: icmp6: echo request

Thanks.

Incredibly, it has begun to work without intervention mine. Thank you very much.
[Linux] Destination unreachable: Address unreachable
Let me guess you didn't read the FAQ entry about syncing or did something utterly stupid yourself and now are trying to point the finger at the SixXS staff trying to say that they secretly fix stuff? Really, if there is something wrong we actually do acknowledge the problem. The biggest reason being that the problem might also occur at other people's networks/hosts/routers and by coming forward with it other people can have an advantage there by not falling into that pit.
PS: You might want to read the main forum page again stating that the forum is a help channel for users and by users. That sometimes a staff or admin member replies is just pure luck as they are not monitoring this place.
As for this part:
PING 2001:b18:2000:12::1(2001:b18:2000:12::1) from 2001:b18:2000:12::2 : 56 data bytes From ::1 icmp_seq=2 Destination unreachable: Address unreachable From ::1 icmp_seq=3 Destination unreachable: Address unreachable From ::1 icmp_seq=4 Destination unreachable: Address unreachable
That can mean two things:
- wrong routing
- Remote tunnel endpoint returns proto-41 unreachable's.
The second nicely notes what is mentioned in the FAQ.

No, I tried to form it during several days, and there was no way. I continue having the same problem. The problem seems to be in proto-41, the tunnel lets work after a time of inactivity.
Once located the problem, I have not returned to ask in the forums, I consider that it is cause of my ineptitude to form it. I have found much information, and although not yet I have been able to make it work correctly, would seem to me a lack of respect to ask.
And yes, I have read the FAQ and other documentation before ask in the forum.
Sorry by my bad english.
