Does anyone know of a simple script that will go through a list of BIND primary files, or more and output a list of output like this:
secondlevel.domain --> address thirdlevel.secondlevel.domain --> address
and so on for several thousand domain files.
I agree with the comment that you ought to use AXFR rather than parsing zone files, since the zone files can have all kinds of irregularities that make it a complex job to parse them, whereas an AXFR client will have predictable output. Much as it pains me to recommend the use of "nslookup" by anybody for anything, it has a reasonable way of doing this: nslookup <<EOF | awk yada yada server $MASTER ls -t A $ZONE EOF If you prefer "dig" then you'll shortly be cursing me for its non-optional shorthand pretty-printing, but once in 1995 when I got done cursing myself for this misfeature, I wrote $BIND8/contrib/misc/normalize_zone.pl, as in dig @$SERVER $ZONE axfr | bind8/contrib/misc/normalize_zone.pl | grep ' IN A ' Hope this helps.
