Need some help with IPv6

I've been working on IPv6 for the last 2 hours or so, but i just can not get it working on my server :(

I have the following in my network config:

iface eth0 inet6 static
pre-up modprobe ipv6
address 2xxx:xxx:6:0292::2
netmask 64
gateway 2xxx:xxx:6:0292::1
dns-nameservers 2001:4860:4860::8888 2001:4860:4860::8844

But i still have the

 inet6 addr: fe80::226:2dff:fe16:1d55/64 

Address at the ifconfig results

Also, can not ping6 any host

Can someone help me with this please?

  • remove the name servers and try it.

  • Can you ping the ipv6 gateway from the vps and from the outside?

    As for the inet6 addr: fe80::226:2dff:fe16:1d55/64 is the internal IPv6. But, can you also post the /etc/resolv.conf?

  • @Joodle - you have rebooted the server after making the changes?

    Still does not work

    Yes

    Just done that, didn't work

  • joodle said: nameserver 127.0.0.1

    That's the causes :)

    Try to modify it to like this :

    nameserver 8.8.8.8
    nameserver 8.8.4.4
    nameserver 2001:4860:4860::8888 
    nameserver 2001:4860:4860::8844
    
  • Been working on it all morning... Google'd a lot, still doesn't work :(

    Also doesn't make any changes.. :(

  • Is this a vps from another provider or your own vps inside your dedi?

  • fe80::/64 is link-local address always there. Maybe gateway not up?

  • @ErawanArifNugroho said:

    This is a dedicated server

    Gateway should be up, i have this line at the interfaces file: "gateway 2605:xxx:x:xxxx::1"

    It looks to me somekind of networkmanager is taking over your manual setup. Distro ?

    It's running Ubuntu 13.10

    Try disabling NetworkManager then do whatever you did before https://help.ubuntu.com/community/NetworkManager

    Getting the following error:

    stop: Unknown job: network-manager

    Already found that website yesterday, nothing did work

    How about disable the IPv6 from the config, and add it manually?

    ip addr add 2xxx:xxx:6:0292::2 dev eth0
    ip -6 r a default via 2xxx:xxx:6:0292::1
    

    Is it works?

    There's 2 persons always help me solving the IPv6 problem, Spirit and rm_

  • ErawanArifNugroho said: How about disable the IPv6 from the config, and add it manually?

    Just did that, it does add the IPv6 addresses, but i can't ping6 google and i can't ping the IPv6 address from either...

    # ping6 google.com
    connect: Network is unreachable

    edit: what does ip -6 r say? Can you ping6 your gateway?

  • edited April 2014

    I need another result from this command :D

    ip -6 a s
    ip -6 r s
    

    Did the IPv6 in /64 or /54?

  • @rds100 said:

    Done this:

    # ip -6 r a default via 2605:xxx:x:xxxx::1

    Getting the following error:

    TNETLINK answers: No route to host
  • ip -6 a add 2xxx:xxx:6:0292:2/64 dev eth0
    ip -6 r a 2xxx:xxx:6:0292::/64 dev eth0
    ip -6 r a default via 2xxx:xxx:6:0292::1

    I mean gateway cannot be properly contacted ( ping6 ) even with correct IPv6 addr. Gateway refuse to route your IPv6 or gateway actually down.
    I guess its a upstream problem?

    ip -6 r a 2xxx:xxx:6:0292::/64 dev eth0
    ip -6 r a default via 2xxx:xxx:6:0292::1

    Awesome this work, i can ping the IPv6 from another server now, but i can not ping IPv6 addresses from the dedicated server

    Edit: Can't connect to the IPv6 ubuntu server either (apt-get)

  • Ok, and ip6tables -L -n ?

    Chain INPUT (policy ACCEPT)

  • So you can't ping6 ipv6.google.com ?

  • All of those IPv6 can be pinged from the outside, except 2605:980:6:292::

  • Interesting that it all goes through a He.net tunnel. I thought Delimiter had native ipv6.

    Correct, i just get massive packet loss

    --- ipv6.google.com ping statistics ---
    15 packets transmitted, 0 received, 100% packet loss, time 14111ms

    I have never had any issues with IPv6 before on other servers...
