Overriding Included Zone File Entries
Hello everyone, I have a question about using the $INCLUDE directive in my zone files. We run DNS for a moderately large number of domains, largely pointing at the same servers. So, I'd really like to have the following setup: db.common.inc: mail IN A n.n.n.n mail2 IN A n.n.n.n www IN A n.n.n.n @ IN TXT "v=spf1..." And then have individual zone files be able to override the various values: db.special.domain.com: $INCLUDE db.common.inc www IN A x.x.x.x Of course, this just round-robins the A record for the www entry. Does anyone know if it is possible to make the new entry override the previously included one rather than add to it? If not, is there a typical config structure that has worked for someone trying to do a similar setup?

If www changes in each view, then do not include it in the common file. If, for example, you have three views, and www is the same in two views and different in the third, then you still have to have www in each view and not in the common file. That then becomes quite painful when a customer asks for a single server to change over a single server, and then 80-or-so other files have to change to accommodate that. Essentially, as much work as not having the include in the first place, for everyday operations. Really wishing for a $OVERRIDE flag, that replaces entries from this point on in the zone file. Thanks for the insight. --Pat ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

I guess this is the most balanced approach. It's still a little cumbersome for if a client asks to override a specific entry in mail.inc or www.inc. But it will have to do. --Pat ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
