Sixxs on dedibox without aiccu
![[fr]](/s/countries/fr.gif) Shadow Hawkins on Thursday, 25 October 2007 16:41:37
Hi,
I have setup an ipv6 tunnel on my dedicated server (dedibox), I can ping my ipv6, the remote ipv6, I can even dig an ipv6 domain name successfully but when I ping this domain it says:
connect: Network is unreachable
I have follow this setup and many other:
https://noc.sixxs.net/faq/connectivity/?faq=ossetup&os=linux
My route seems correct:
Table de routage IPv6 du noyau
::/0 2001:6f8:202:204::1 UG 1024 0 0 sixxs
I can't install debian aiccu package because it's for debian unstable...
If it can help, here is my PoP: bebru01.sixxs.net
Anyone can help ? Thanks

I finally found a working tutorial but I don't understand why the other one didn't work.
I can finally gain credit again 8-)

[ you might want to read Reporting Problems to figure out what goes wrong where]
I can even dig an ipv6 domain name successfully
As DNS gets transported over either IPv4 or IPv6 and you can resolve AAAA and A over either, being able to resolve something doesn't mean connectivity works.
but when I ping this domain it says: connect: Network is unreachable
And what does traceroute tell you? Or better phrased: which host/router is stating that it is unreachable?
My route seems correct: Table de routage IPv6 du noyau ::/0 2001:6f8:202:204::1 UG 1024 0 0 sixxs
If that are all the routes, you are definitely missing a couple.
For instance a route to the gw given there is useful.
Otherwise, depending on your kernel version, you might need a 2000::/3 route.
But if that is the case you are using a quite old kernel which you should really upgrade due to a number of security issues.
I can't install debian aiccu package because it's for debian unstable...
AFAIk, Debian provides packages or all distributions. Otherwise you can take it from backports.
Then again, aiccu won't resolve the above misconfiguration for you as it doesn't have any possible ability to know what it is 'good configuration' and what is 'bad configuration' as such it won't touch the existing configuration as that will be there most likely for a purpose.

First, thanks for this fast reply,
-For the DNS, I forgot the v4 transport, sorry.
-traceroute, only display * even on the first hop, which I can ping.
-For the routes, yes I have many others, I can post them if it help.
-For the aiccu package, I don't have backports activates.
(I have read the "Reporting problems", I'll do better this time)

Thanks for your help, and sorry for the first post, I hope I haven't forget anything this time.

Try adding a 'default' route using:
ip -6 ro add 2000::/3 via 2001:6f8:202:204::1 dev sixxs
as there was a 2.6.20 version which was broken for that. As they are at 2.6.23 you might want to upgrade it a bit to see if that really is the issue.
