Hi guys,

I've read a few topics about the same problem here but, despite the same message, I think my problem is different.

I've received from the certification page the link as http://ipv6.ces.eti.br/fxxd86upzt.txt. When I hit "Test It!", the page reports back "Could not grab the file via IPv6 HTTP". The problem is that I actually CAN grab the file both locally and remotely from another site.
Not only a do can grab the file, I'm also accessing this server remotely (both WWW and SSH) via IPv6 from another network (two others, actually).

I'm in control of my DNS records and the AAAA is resolving correctly (hence the web access thru IPv6).

Any ideas?

Thanks in advance!

It works for me too, but HE doesn't know about it

Code:

[carl@mars]$ dig aaaa ipv6.ces.eti.br @2001:470:200::2

; <<>> DiG 9.6.2-P2 <<>> aaaa ipv6.ces.eti.br @2001:470:200::2

How long ago did you enter the DNS information?  Might have to wait a day or so, or email ipv6@he.net to have them kick the server

I entered the info yesterday.

But I think you mistyped the address (2001:470:200::2 instead of 2001:470:20::2). I've tried and that's the result:

Code:
root@Apolo:~# dig ipv6.ces.eti.br @2001:470:20::2 AAAA

; <<>> DiG 9.7.1-P2 <<>> ipv6.ces.eti.br @2001:470:20::2 AAAA

root@Apolo:~#

So the server at he.net should know about my server... Strange...  Undecided

nah, that's the address for ns2.he.net and the one I always use.

Code:
[carl@mars]$ host ns2.he.net
ns2.he.net has address 216.218.131.2
ns2.he.net has IPv6 address 2001:470:200::2

Hmmm... Very strange...
One server has the info ("opcode: QUERY, status: NOERROR, id: 50965") and the other one doesn't ("opcode: QUERY, status: SERVFAIL, id: 31766") Huh

Thanks, man. That seemed to do the trick.
Already passes that step. I only hope the next one works too.  Cheesy

im having a similar problem.

Im not 100% sure I have set my IIS server up correctly but it appears to be working fine.

my domain name id d33n.ag33k.net it should hopefully resolve to 2001:470:1f08:113e::2

I'll run through my set up quickly.

Draytek 2710n in routed mode, my windows 7 machine has one of my 8 IPv4s and my FreeNAS (FreeSBD based) box has another.  I terminated one tunnel on my W7 and one on my NAS.

Opened up protocol 41 in the firewall and i can confirm i get an IPv6 Address as above.  I have tried both apache on the NAS and IIS on W7.

THanks

DNS does indeed work

Code:
[carl@mars ~]$ host d33n.ag33k.net
d33n.ag33k.net has IPv6 address 2001:470:1f08:113e::2

I can ping the address, but I am unable to connect via HTTP.

IIS should listen on IPv6 by default...did you allow HTTP connections to that host via IPv6 in your firewall?

sorted, windows firewall after all.

Any tips on what to enable, i just turned it off for a few mins.  I have opened up ICMPv6 and Protocol 41 which it lists as IPV6 as well as http

If you want to keep getting the certs, you'll want to enable SMTP as well.

I'm having the same problem with http://ewanm89.co.uk/262sc8ss8a.txt, I can get it over ipv6 http myself, but the certification server can't seem to. Even though he.net nameservers are my SOA servers and AAAA record is set.

I think I can get to your file, but it looks like there's nothing in it to get?

I think you should place some text into the file..."262sc8ss8a.txt" would be a good start.

Other than that, DNS looks correct and HE knows about it

Code:

[carl@mars ~]$ dig aaaa ewanm89.co.uk @ns2.he.net

; <<>> DiG 9.6.2-P2 <<>> aaaa ewanm89.co.uk @ns2.he.net
;; global options: +cmd

;; QUESTION SECTION:
;ewanm89.co.uk.                 IN      AAAA

;; ANSWER SECTION:
ewanm89.co.uk.          86400   IN      AAAA    2a01:7b8:2000:26::1

Oh, this is interesting

Code:

[carl@mars ~]$ wget http://ewanm89.co.uk/262sc8ss8a.txt

I can get your file over IPv4, but not IPv6
