Explorer Test - Please help

[yhamidi]

Hi there,

I have a linux machine with a public IP (no NAT). I set up the tunnel and everything seems to be ok: I can ping6 to other IPv6 addresses, for ex. (IPv6 endpoint of my Tunnel on HE Tunnel Server). Even a friend of mine can ping6 to my linux box. But at the certification page, it displays:
----------------
In the Explorer level, we will need to check if you have IPv6 connectivity:

You were unable to load a content from an IPv6 only URL. Here's an exmple of the IPv6 only URL: http://[2001:DB8::1]/
....
Explorer Test Result: Not passed
----------------

Am I missing something here, tell me please !
If you want to check my connectivity, here is my IPv6 address: 2001:470:1f12:deb::2

Thank you very much in advance !

1) can you access http://ipv6.google.com ?
2) did you assign an address to eth0 (or whatever interface) from your routed /64?

[yhamidi]

Thank you for your reply !
1) I can't access ipv6.google.com
 wget -6 http://ipv6.google.com
--2012-03-20 09:55:33--  http://ipv6.google.com/
Resolving ipv6.google.com... 2a00:1450:4007:804::1011
Connecting to ipv6.google.com|2a00:1450:4007:804::1011|:80... failed: Network is unreachable.


2)
Here is the output of ifconfig:

Code:

          inet addr:196.200.131.145  Bcast:196.200.131.191  Mask:255.255.255.192

Thank you for your help once again !

I assigned an IPV6 address to my eth0 from the HE address range and when I do a ping6 to google:

Code:

[root@www ~]# ping6 ipv6.google.com
PING ipv6.google.com(par03s03-in-x13.1e100.net) 56 data bytes

64 bytes from par03s03-in-x13.1e100.net: icmp_seq=2 ttl=56 time=81.7 ms

but with a wget:

Code:

[root@www ~]# wget -6 http://ipv6.google.com
--2012-03-20 12:39:21--  http://ipv6.google.com/

Retrying.

here is my ifconfig output:

please help !

[cholzhauer]

You're ring the wrong ranges. The 2001:470 address you have is part of your tunnel /64 not your routed /64...fix that

Next, what is that other address?  Might want to remove that too

[yhamidi]

Thank you cholzhauer !
This is exactly what I've done:

Code:

ip tunnel add he-ipv6 mode sit remote 216.66.84.42 local 196.200.131.145 ttl 255
ip link set he-ipv6 up
ip addr add 2001:470:1f12:deb::2/64 dev he-ipv6
ip route add ::/0 dev he-ipv6
ip -f inet6 addr

and I issued the command:

Code:

ip addr add 2001:470:1f13:deb::1/64 dev eth0

My routed /64 is 2001:470:1f13:deb::/64

The other IPv6 address (eth0) is autoconfigured (2001:4310:110:1:250:56ff:fe9a:6968)
Now here is my ifconfig output:

Code:

[root@www ~]# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:50:56:9A:69:68
          inet addr:196.200.131.145  Bcast:196.200.131.191  Mask:255.255.255.192

I did a test with HE looking glass and it's working. However, when ping6 to ipv6.google.com, sometimes it works, sometimes not !!!
and even in the explorer test result, it's saying Not passed

Thanx once again !

[cholzhauer]

Where are you getting that autoconfigured address?  I'm 90% sure that is what's causing your problem

[yhamidi]

I'm on a CentOS machine.
I added these lines to my /etc/sysctl.conf to disable autoconfiguration:

Code:

net.ipv6.conf.all.autoconf=0
net.ipv6.conf.all.accept_ra=0

reboot the machine and even issued :

Code:

ifconfig eth0 inet6 del 2001:4310:110:1:250:56ff:fe9a:6968/64

to delete the autoconfigured @

but in vain ! the autoconfigured @ still shows up !

I can ping6 google and wget -6 but the test result is "not passed"

I'll try to dig it more !
Thank you so much cholzhauer for your help !

[cholzhauer]

What device is doing auto configure on your network? 

Can you actually browse to ipv6.google. com?  What I assume is happening is that you're trying to connect to do the test with that non he address hd that address is pointing you to a broken router or something.

[yhamidi]

Hi cholzhauer,

I think you are right. I'll discuss it with some guys here and let you know.
Thanx for your directions

[marins82]

1) can you access http://ipv6.google.com ?
2) did you assign an address to eth0 (or whatever interface) from your routed /64?

I have the same problem, but on the machine ipv6.google.com navigate. But explorer test does not pass
