Hi folks,
i am a real newbie in the ipv6 world, and i wanted to equip my rootserver with ipv6 so i can use a ipv4/ipv6 mixed playground VE.
I am using Ubuntu "Hardy" with the following Kernel: 2.6.24-19-openvz
In the HN (hardware node, hostname august) everything works fine:
root@august:~# ping6 ipv6.google.com
PING ipv6.google.com(fx-in-x68.google.com) 56 data bytes
64 bytes from fx-in-x68.google.com: icmp_seq=1 ttl=58 time=30.0 ms

rtt min/avg/max/mdev = 30.084/30.530/30.784/0.347 ms
root@august:~# ifconfig

Now, i have ipv6 forwarding active:
root@august:~# cat /proc/sys/net/ipv6/conf/all/forwarding
1
So i create a new VE with id 504 giving it the IPv6 address 2001:470:1f13:113::2, which is whithin my routed /64 subnet The VE is called "ipv6".
From within the virtual machine i see the following:
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
venet0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00
inet addr:127.0.0.1 P-t-P:127.0.0.1 Bcast:0.0.0.0 Mask:255.255.255.255

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
...and i can ping6 my own ipv6 address from within the virtual machine:
root@ipv6 / $ ping6 2001:470:1f13:113::2
PING 2001:470:1f13:113::2(2001:470:1f13:113::2) 56 data bytes
64 bytes from 2001:470:1f13:113::2: icmp_seq=1 ttl=64 time=0.035 ms
64 bytes from 2001:470:1f13:113::2: icmp_seq=2 ttl=64 time=0.040 ms
But i CAN NOT ping ANY other ipv6 address such as for example my hn:
root@ipv6 / $ ping6 2001:470:1f12:113::2
connect: Network is unreachable
Checking the routing from whithin the VE shows me that this is true as NO route except a "host route" to the own address is set:
root@ipv6 / $ route -6n
Kernel IPv6 routing table
Destination Next Hop Flag Met Ref Use If
::1/128 :: U 256 0 0 venet0
2001:470:1f13:113::2/128 :: U 256 0 0 venet0
fe80::/64 :: U 256 0 0 venet0
::/0 :: !n -1 1 2245 lo
::1/128 :: Un 0 1 3 lo
::1/128 :: Un 0 1 0 lo
2001:470:1f13:113::2/128 :: Un 0 1 10 lo
ff00::/8 :: U 256 0 0 venet0
::/0 :: !n -1 1 2245 lo
Now i do not know this openvz style venet stuff so good to know what route to set. A default route is what i would need, but which nexthop? There is none reachable....
Any ideas how to do that?
Thanks in advance
