Title: ubuntu - problems bring up ipv6 tunnel
Post by: brez on December 31, 2008, 11:35:52 PM
Hey,

I'm quite new too the ipv6 scene. I use ubuntu 8.10. I have managed to get a tunnel working through tspc, how ever I have no luck when trying to use one through HE.net. I followed the config on the website and all seems fine but I'm not able to ping6 anything..

Everytime I do this command; I get

Code: [Select]
brett@cooldessin:~$ sudo ifup he-ipv6
ioctl: No buffer space available
Failed to bring up he-ipv6.

This is what my /etc/network/interfaces looks like - Is there anything wrong, or any idea as to why I'm getting that error message. It even happens after a fresh reboot.

Code: [Select]
     # IPv6 via HE tunnel...
    auto he-ipv6
    iface he-ipv6 inet6 v4tunnel
        address 2001:470:1f04:99a::1/64
        netmask 64
        remote 72.52.104.74
        local 220.238.66.228
        endpoint any
        ttl 64
        up      ip -6 route add 2000::/3 via ::72.52.104.74 dev he-ipv6
        up      ip -6 addr add 2001:470:1f05:99a::/64::1:1/128 dev he-ipv6
       #up      ip -6 addr add 2001:470:1f05:99a::/64::2:1/128 dev he-ipv6
        down    ip -6 route flush dev he-ipv6

Your side of the tunnel ni the 1f04 space would end ::2, first glaring problem i see

It might be too early for me to comprehend or I may just be really dumb - but would you be able to post the string exactly what I should replace it with. Would be much appreciated!

Code: [Select]
address 2001:470:1f04:99a::1/64assignes an ip to the interface.
However if you look on your settings or above ::1 is on the server side.
Your ip is 2001:470:1f04:99a::2/64 giving this:
Code: [Select]
address 2001:470:1f04:99a::2/64

Thanks I'll try that when I get home from work,

Would that have anything to do with the buffer error I'm recieving?

Guess what - I don't (yet) know:
But after using google:
About: ioctl: No buffer space available
"Due to lazy programming, this ioctl will return ENOBUFS even if it is register_netdevice() that fails."
