[Aurora-sparc-user] IPv6

[Hans Witvliet]

Hi list,

to continue my original tests with IPv6, i followed the instructions
from my tunnel brooker (H.E.)

I did:
modprobe ipv6
ip tunnel add sixbone mode sit remote 64.71.128.83 local 82.161.99.204
ttl 255
ip link set sixbone up
ip addr add 2001:470:1F03:E65::2/64 dev sixbone
ip route add ::/0 dev sixbone
ip -f inet6 addr

And from their website i can do a ping6 to either end of the tunnel.
So it seems to work! 
However, when testing locally i can NOT ping6 at all, not even
localhost ::1

My tests:
#!/bin/sh
cat /proc/net/if_inet6

lsmod |grep v6

echo "testing locally loopback"
ping6 ::1 -c 2 -w 1
echo $?
echo "testing my end of the tunnel"
ping6 2001:470:1F03:E65::2 -c 2 -w 1
echo $?
echo "testing remote end of the tunnel"
ping6 2001:470:1F03:E65::1 -c 2 -w 1
echo $?
echo "ip addr show"
ip addr show
echo "route --inet --inet6"
route --inet --inet6
echo "ip6tables -L -n"
ip6tables -L -n

And the (lack of) results:
# ./test_v6.sh

ip6tables v1.2.5: can't initialize ip6tables table `filter': Table does
not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

Any (6) suggestions?
The tunnel is working OK, so the kernel knows about V6...
