Linux Auto IPv6 Tunneling

[badcrc]

I am running Ubuntu Linux 8.10 on one of my desktop systems not provided an IP from the server in my last thread. What I would like to know, is there a way to make an auto connection at boot?

Here is my '/etc/network/interfaces' file:

john@earth:~$ cat /etc/network/interfaces
auto he-tunnel
iface he-tunnel inet static
address 2001:470:a:1ec::2/64
netmask 64
gateway 2001:470:a:1ec::1/64
up ip -6 route add ::/0 dev he-tunnel
down ip -6 route del ::/0 dev he-tunnel
mtu 1500

auto he-ipv6
iface he-ipv6 inet6 v4tunnel
endpoint 216.218.226.238
address 2001:470:a:1ec::1/64
netmask 64
up ip -6 route add default dev he-ipv6
down ip -6 route del default dev he-ipv6
mtu 1500

auto ath0
iface ath0 inet static
address 192.168.1.69
netmask 255.255.255.0
gateway 192.168.1.1
mtu 1500

auto lo
iface lo inet loopback


Here is the output of 'ifconfig':

What is going on here is that the IPv4 setup on 'ath0' is working fine and the logical device 'he-ipv6' is being created, but the link to the Tunnel Server on 'he-tunnel' as defined in the interfaces file is not being created and established.

Any ideas how I can easily make this happen? Thank you.

Try bringing the interface up/down manually to see what error messages are displayed (you may want to bring it down first if it got started automatically):

Code Select Expand

# ifdown he-ipv6
# ifup he-ipv6

If you want to setup a tunnel, something like this should work (note that there's no '/64' behind the address):

Code Select Expand


auto he-ipv6
iface he-ipv6 inet6 v4tunnel
        endpoint 216.218.226.238
        address  2001:470:a:1ec::2
        netmask  64
        up       ip route add 2000::/3 via 2001:470:a:1ec::1

I'm not sure what you want with the he-tunnel interface, but you probably don't need it.
