dig @master zone SOA
dig @slave zone SOA
check that serials match
if not, work out why and fix
Check whether slave is tracking master:
update zone on master
dig/dig/check once more
if not matched, as before
dig/dig/check as often as is reasonable
treat a mismatch as a problem
No doubt many people have written scripts to do this. Even if
you end up preferring someone else's, writing your own once is
a good way to learn what's involved.
I'm not familiar with any except my own. These 'work for me',
but aren't packaged attractively enough for me to inflict them
on others. 8-)
If your zones are properly delegated, and your servers accessible
from the public Internet, then the web-based remote-checking tools
available at www.zonecheck.fr or dnscheck.iis.se are excellent.
Either of these will give you some ideas about what to include in
the script you want to write.
