PGSQL BIND SDB driver
|
|
|
bc5dde |
|
|
|
bc5dde |
The postgresql BIND SDB driver is of experimental status and should not be
|
|
|
bc5dde |
used for production systems.
|
|
|
bc5dde |
|
|
|
bc5dde |
Usage:
|
|
|
bc5dde |
|
|
|
bc5dde |
o Use the named_sdb process ( put ENABLE_SDB=yes in /etc/sysconfig/named )
|
|
|
bc5dde |
|
|
|
bc5dde |
o Edit your named.conf to contain a database zone, eg. :
|
|
|
bc5dde |
|
|
|
bc5dde |
zone "pgdb.net." IN {
|
|
|
bc5dde |
type master;
|
|
|
bc5dde |
database "pgsql bind pgdb localhost pguser pgpasswd";
|
|
|
bc5dde |
# ^- DB name ^-Table ^-host ^-user ^-password
|
|
|
bc5dde |
};
|
|
|
bc5dde |
|
|
|
bc5dde |
o Create the database zone table
|
|
|
bc5dde |
The table must contain the columns "name", "rdtype", and "rdata", and
|
|
|
bc5dde |
is expected to contain a properly constructed zone. The program "zonetodb"
|
|
|
bc5dde |
creates such a table.
|
|
|
bc5dde |
|
|
|
bc5dde |
zonetodb usage:
|
|
|
bc5dde |
|
|
|
bc5dde |
zonetodb origin file dbname dbtable
|
|
|
bc5dde |
|
|
|
bc5dde |
where
|
|
|
bc5dde |
origin : zone origin, eg "pgdb.net."
|
|
|
bc5dde |
file : master zone database file, eg. pgdb.net.db
|
|
|
bc5dde |
dbname : name of postgresql database
|
|
|
bc5dde |
dbtable: name of table in database
|
|
|
bc5dde |
|
|
|
bc5dde |
Eg. to import this zone in the file 'pgdb.net.db' into the 'bind' database
|
|
|
bc5dde |
'pgdb' table:
|
|
|
bc5dde |
|
|
|
bc5dde |
---
|
|
|
bc5dde |
#pgdb.net.db:

|

Issue this command as the pgsql user authorized to update the bind database:
|
|
|
bc5dde |
|
|
|
bc5dde |
# zonetodb pgdb.net. pgdb.net.db bind pgdb
|
|
|
bc5dde |
|
|
|
bc5dde |
will create / update the pgdb table in the 'bind' db:
|
|
|
bc5dde |
|
|
|
bc5dde |
$ psql -dbind -c 'select * from pgdb;'
|
|
|
bc5dde |
name | ttl | rdtype | rdata

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

|
|
bc5dde |
service .
