PGSQL BIND SDB driver The postgresql BIND SDB driver is of experimental status and should not be used for production systems. Usage: o Use the named_sdb process ( put ENABLE_SDB=yes in /etc/sysconfig/named ) o Edit your named.conf to contain a database zone, eg. : zone "pgdb.net." IN { type master; database "pgsql bind pgdb localhost pguser pgpasswd"; # ^- DB name ^-Table ^-host ^-user ^-password }; o Create the database zone table The table must contain the columns "name", "rdtype", and "rdata", and is expected to contain a properly constructed zone. The program "zonetodb" creates such a table. zonetodb usage: zonetodb origin file dbname dbtable where origin : zone origin, eg "pgdb.net." file : master zone database file, eg. pgdb.net.db dbname : name of postgresql database dbtable: name of table in database Eg. to import this zone in the file 'pgdb.net.db' into the 'bind' database 'pgdb' table: --- #pgdb.net.db: $TTL 1H @ SOA localhost. root.localhost. ( 1 3H 1H 1W 1H ) NS localhost. host1 A 192.168.2.1 host2 A 192.168.2.2 host3 A 192.168.2.3 host4 A 192.168.2.4 host5 A 192.168.2.5 host6 A 192.168.2.6 host7 A 192.168.2.7 --- Issue this command as the pgsql user authorized to update the bind database: # zonetodb pgdb.net. pgdb.net.db bind pgdb will create / update the pgdb table in the 'bind' db: $ psql -dbind -c 'select * from pgdb;' name | ttl | rdtype | rdata ----------------+------+--------+----------------------------------------------------- pgdb.net | 3600 | SOA | localhost. root.localhost. 1 10800 3600 604800 3600 pgdb.net | 3600 | NS | localhost. host1.pgdb.net | 3600 | A | 192.168.2.1 host2.pgdb.net | 3600 | A | 192.168.2.2 host3.pgdb.net | 3600 | A | 192.168.2.3 host4.pgdb.net | 3600 | A | 192.168.2.4 host5.pgdb.net | 3600 | A | 192.168.2.5 host6.pgdb.net | 3600 | A | 192.168.2.6 host7.pgdb.net | 3600 | A | 192.168.2.7 (9 rows) I've tested exactly the above configuration with bind-sdb-9.3.1+ and it works OK. NOTE: If you use pgsqldb SDB, ensure the postgresql service is started before the named service . USE AT YOUR OWN RISK!
