Issue with ipv6 on debian

Hey,

On my server i am trying to install an ipv6 and i used slackware before

and this script worked with slackware butdoes not work with my debian

install. It adds the tunnel and the ip address to eth0 but it also adds

/96 blocks that i did not ask it to and it does not seem to have a route

to the tunnel.

script: http://wolfnix.net/ipv6

ifconfig output: http://wolfnix.net/ifconfig

traceroute6:

debglade:/etc/bind# traceroute6 irc6.oftc.net

traceroute to irc6.oftc.net (2001:968:1::6666) from

2001:618:400::4655:103f, 30 hops max, 16 byte packets

1 * * *

debglade:/etc/bind# traceroute6 sixxs.net

traceroute to sixxs.net (2001:838:1:1:210:dcff:fe20:7c7c) from

2001:618:400::4655:103f, 30 hops max, 16 byte packets

Any help would be great

Thanks

I use the hurricane electric V6 tunnel broker. Once you've got

yourself an address allocated, this script works very well:

Seems that you'll need to do the ipv6 config immediately after rebooting. Otherwise your memory might be too fragmented.
