rndc addzone for subnetted reverse zones

[Mark Andrews]

This is a bug.  A ticket has been opened.

In message <43642AC5-FADD-46EB-9658-45044963AA16 at sonic.net>, Charles Musser wri
tes:
> We are trying to manage almost all zones served by a slave dynamically via
> addzone and delzone, but are having trouble with subnetted reverse zones.
> The problem is that adding the zone is successful (it's resolvable), but the
>  entry written to the NZF file causes errors when the server is reloaded or
>  restarted. An example:
> 
> 1. Add the zone via rndc:
> 
>    /usr/sbin/rndc addzone \"160/27.3.2.1.in-addr.arpa\" '{ type slave; file "
> 160-27.3.2.1.in-addr.arpa"; masters { 5.6.7.8; }; };'
> 
>    Note the escaped quotes, required to avoid an "unexpected token" error
>    from rndc. At this point dig can resolve this zone. The NZF file contains
>    this line:
> 
>    zone 160/27.3.2.1.in-addr.arpa { type slave; file "160-27.3.2.1.in-addr.ar
> pa"; masters { 5.6.7.8; }; };
> 
> 2. Restart named via "rndc reload". This causes the following message to
>    appear in the syslog:
> 
>    named[1275]: config: error: 3bf305731dd26307.nzf:71066: '{' expected near 
> '/'
> 
>    At this ping, no zones specified in the NZF file are loaded according to
>    "rndc status" and queries are refused.
> 
> 3. Edit the NZF so that this zone's name is quoted, as shown below:
> 
>    zone "160/27.3.2.1.in-addr.arpa" { type slave; file "160-27.3.2.12.in-addr
> .arpa"; masters { 5.6.7.8; }; };
> 
>    Issuing an "rndc reload" now causes the server to load the zones and answe
> r
>    queries.
> 
> It seems that quotes are required if the zone name contains a slash (and
> possibly other characters) and whatever is in charge of writing that file is
> not quoting the name when necessary. But maybe we're doing this the
> wrong way.
