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.

output. Much as it pains me to recommend the use of "nslookup" by anybody for anything, it has a reasonable way of doing this:

The new version of host (i.e. the one that's usually only slightly out of date in the BIND contrib directory, NOT the junky old useless one in the main BIND src/bin directory) is much less painful to recommend (and has equally regular and predictable output): host -a -l $ZONE $SERVER | awk 'blah' You can of course have 'host' do the filtering for only specific types of records too. For example to display only 'A' records: host -t a -l $ZONE $SERVER | awk 'blah' You can even omit the $SERVER parameter and 'host' will try all the authoritative servers until it succeeds. -- Greg A.
