RPZ zone load failure ran out of space

[Jim Yang]

Hi,

 

In the example below, when the length of bad.domain.com reaches 241 bytes, named-checkconf reports the following error:

 

“zone db.rpz.zone/IN: loading from master file db.rpz.zone failed: ran out of space

_default/db.rpz.zone/IN: ran out of space”

 

As per RFC1035, the DNS name maximum length is 255 bytes and each label length limit is 63 bytes.

 

I wonder what is the maximum length for bad.domain.com in the RPZ zone?

 

$ORIGIN rpz.example.com.

      $TTL 1H

      @               SOA LOCALHOST. named-mgr.example.com (1 1h 15m 30d 2h)

                      NS  LOCALHOST.

 

      ; QNAME policy records.

      ; Note: There are no periods (.) after the (relativised) owner names.

 

bad.domain.com      A       10.0.0.1      ; redirect to walled garden

                          AAAA    2001:2::1

 

Thanks,

Jim

I just hit the same problem (we probably use the same block list source).

The actual DNS name is the combination of the ORIGIN and the entry:
bad.domain.com.rpz.example.com.
which exceeds 255 characters including the trailing dot, most likely.

Hi Bob,

Thank you for the explanation. It makes sense to me now.

Best,

Jim
