[SURBL-Discuss] RE: Add "$DATASET dnset @" directive to SURBL rbldnsd zone files?

Dallas Engleken of SARE has suggested that we add a dataset directive to our rbldnsd zone files:

...

Can we please add a $DATASET definition to rbldnsd zone

files for sc,ws,

...

and be?

Ie.. On the 3rd line after $NS and $SOA, add a line labeled,

$DATASET dnset @

It will not break anything currently set up, but it will

give those of

...

use that use the 'combined' type with multi files in rbldnsd

(called via

...

uribl.surbl.org:combined:sc,be,ws) to merge ws, sc, and be

together to

...

create a single query.

Does anyone have any comments on this, good, bad or otherwise? Do other RBLs do it? Is it safe?

Here's the man page entry: :-)

...

man rbldnsd

   combined
          This is a special dataset that stores no data 

by itself but acts

...

          like a container for several other datasets of 

any type except

...

          of  combined  type  itself.   The data file 

contains an optional

...

          common section, where various specials are 

recognized like $NS,

...

          $SOA,  $TTL (see above), and a series of 

sections, each of which

...

          defines one (nested) dataset and several 

subzones of the base

...

          zone,  for which this dataset should be 

consulted. New (nested)

...

          dataset starts with a line
            $DATASET type subzone subzone...
          and all subsequent lines up to the end of  

current file or to

...

          next  $DATASET line are interpreted as a part 

of dataset of type

...

          type.  Note that combined datasets cannot be 

nested. Every subâ

...

          zone  will always be relative to the base zone 

name specified on

...

          command line.  If subzone specified  as  

single character "@",

...

          dataset will be connected to the base zone itself.

          This dataset type aims to simplify subzone 

maintenance, in order

...

          to be able to include several subzones in one 

file for easy data

...

          transfer,  atomic  operations  and  to be able 

to modify list of

...

          subzones on remote secondary nameservers.

          Note that $NS and $SOA values applies to  the  

base zone only,

...

          regardless of the placement in the file.  

Unlike the $TTL values

...

          and $n substitutions, which may be both global 

and local for a

...

          given (subâ)dataset.

Thumbs up or thumbs down? ;-)

But we are combining them anyway? Well WS and BE combined. So it would be WS and SC. I see no reason not to try it.
