And I finally gotten enough cycles to write a script to do this and released it
on Google Code ( https://code.google.com/p/dns-slave-expire-checker/ ). It is
very simple, but if folk find it useful I can add additional functionality...
It is a simple Python program:
./dns_expire_checker.py -r
I review the BIND syslogs on my servers daily. The syslog will
tell me if any slave is having problems loading a zone.
I expect that the hostmasters at my off-site slaves do the same.
If I slave a zone for someone else, and I see problems, I contact
the owner of that zone.

I try to catch zones that are not updating on the slaves
to which I have access. I compare the modtime of the zone
file with the current time and the refresh interval
for the zone. Typically I allow a failure or two
before alerting, e.g. wait 1 refresh + 2 retry intervals.

Hello Hugo,
I recently wrote a small script which mails me about any zones that is due to
expire within the next 24 hours. This works by using the last change time of
the file on disk and the SOA expiry time

Hugo,
“zones” don’t “expire”, like DNSSEC RRSIG with their “end of validity time
stamp”.
At worst, a slave name server is unable to verif

Hope this helps.

Marc,
This example was maybe not the best one.
My questions remains as other zones are well unavailable on all name servers.

Dear all,
Is there a way to check that
Method 1: Compare the timestamp on the slave zone file with the system's
current date. Compare that difference with the expire timer in the SOA record
in the same zone file. If the difference is greater than the expire timer, then
the zone is expired.
Method 2: Check the logs.

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
