PowerDNS Automatic Autoreverse generator for IPv6 addresses
Required software
You'll need following perl modules for this software to work
- JSON::Any
- JSON::XS,JSON::DWIW or JSON
- DBI
- DBD::mysql, DBD::sqlite or DBD::Pg
For debian users
apt-get install libjson-any-perl libjson-xs-perl libdbi-perl
MySQL
apt-get install libdbd-mysql-perl
SQLite3
apt-get install libdbd-sqlite3-perl
PostgreSQL
apt-get install libdbd-pg-perl
PowerDNS configuration
Minimum required version of PowerDNS is 3.3.
Make sure your schema has been upgraded, as this script expects your schema to conform with the one recommended for 3.3. You should have 'auth' field in records table, and domainmetadata table present. The auth field is only required to be present, if you enable DNSSEC support, otherwise the value is ignored.
Use the following configuration in powerdns config file for mysql
launch=remote,gmysql
remote-connection-string=pipe:command=/path/to/rev.pl,timeout=2000,dsn=DBI:mysql:database,username=user,password=pass
remote-dnssec=yes/no # depending on your choice
Use the following configuration in powerdns config file for sqlite
launch=remote,gsqlite3
remote-connection-string=pipe:command=/path/to/rev.pl,timeout=2000,dsn=DBI:SQLite:dbname=/path/to/db,username=user,password=pass
remote-dnssec=yes/no # depending on your choice
Use the following configuration in powerdns config file for postgresql
launch=remote,gpgsql
remote-connection-string=pipe:command=/path/to/rev.pl,timeout=2000,dsn=DBI:Pg:dbname=database;host=127.0.0.1;port=5432,username=user,password=pass
remote-dnssec=yes/no # depending on your choice
pipe backend is recommended. if you want to use unix or http, you need to do extra work. For unix connector mode it is possibly enough to use socat.
If you want to change the default prefix 'node' into something else, add prefix=something in the connection string.
Configuring zones
To enable autorev feature for zones, you'll need a reverse and forward zone. Add into domain metadata following entries
for forward zone
AUTODNS, id-of-reverse-zone
for reverse zone
AUTODNS, id-of-forward-zone
The script uses this information to pick up your forward and reverse zones and serve them via the script.
If you want to configure per-domain prefix for the value, use AUTOPRE key for this.
WARNING: Rectify-zone is not currently supported thru the script, so you need to either disable dnssec, or run rectify-zone thru gmysql (or gsqlite3/gpgsql).
DNSSEC
To enable DNSSEC you need to first run secure-zone and then set-nsec3 with narrow. Only NSEC3 narrow is supported for forward zones, you can use NSEC/NSEC3 non-narrow for reverse zones.
