Re: [xwiki-devs] [foaf-protocols] DNS problem with foafssl.org -> myxwiki - xwiki-devs@xwiki.org

14 Sep 2010

I seem to have DNS problems on myxwiki. I can't yet tell if this is a problem with
foafssl.org
or with myxwiki.org, but I think it is with xwiki. Below is an extract of what Dirk
 (Chief Architect of the BBC) has to say

 I suspect that DNS has not changed that much since then. 

  # dig  ns myxwiki.org

 Ok.

 So an answer; but whatever answers is not authoritive.

 myxwiki.org.		8	IN	NS	lanai.xpertnet.biz.
 myxwiki.org.		8	IN	NS	maui.xpertnet.biz.
 myxwiki.org.		8	IN	NS	ns-fr.xpertnet.biz.
   These should be auhtoriative.

 # dig -t any @maui.xpertnet.biz  
 So you are asking these.

 And no answer.

  ;; AUTHORITY SECTION:

   And defers you to the root servers. And it is sure of that.

 -> conclusion - this guy is not configured as your dns server; i.e. it does not know
your zone.

  # dig -t any @ns-fr.xpertnet.biz
                    [[ AT THIS POINT IT HANGS FOR A WHILE]]
 ; <<>> DiG 9.3.3rc2 <<>> -t any @ns-fr.xpertnet.biz
 ; (1 server found)
 ;; global options:  printcmd
 ;; connection timed out; no servers could be reached  
 And this guy is not running at all. Or in other words - your entire domain is foobar -
but luckily not with huge TTL's or anything - so it is not hard to recover; either
have the authoritive servers fixed - or move it somewhere else. If you are stuck - let me
know - happy to run some zones over here or pull zones from SVN/hidden-master. 
If I run this from a server in Ireland I get

$ dig -t any @ns-fr.xpertnet.biz

; <<>> DiG 9.6.0-APPLE-P2 <<>> -t any @ns-fr.xpertnet.biz
; (1 server found)
;; global options: +cmd

Which sounds like the problem is the same here.
