Hugo,

 

This must be a configuration error on "ns2.skynet.be."

The other 3 authoritative name servers answer fine, for omega-pharma.be;

ns2.skynet.be. returns the list of root name servers, meaning it isn't
configured to be slave for that domain.

 

Contact Skynet/Belgacom helpdesk to get this corrected.

Kind regards,

Subject: how to check if a slave zone is expired

 

Dear all,
 
Is there a way to check that a slave zone is expired?
I use dig in the following way to see that the zone is not responding on
my server...but is this due to the fact that the zone is expired or
another problem?
 
dnszone002:/etc/bind/zones/slave# dig @localhost omega-pharma.be soa
 
; <<>> DiG 9.3.4 <<>> @localhost omega-pharma.be soa
; (1 server found)
;; global options:  printcmd

.                       518400  IN      NS      M.ROOT-SERVERS.NET.

 
- How can I see that it is because the zone is expired? 
 
- Is there a way to visualise all the zones that are expired (to make a
cleanup of the configuration)
 
 
Thanks for your feedback,
 
Hugo,
