Installation

This module can be installed from pypi website.

This command will install the module with yaml support for loading zone data.

pip install unbound_console[yaml]

If loading a zone using yaml is not required use the following command, zone data can instead be loaded through the LocalZone object:

pip install unbound_console

Remote Control on Unbound

Before to use this utility. You must activate the remote control on your unbound server. See config file example.

Execute command

You can execute commands with the function send_command. See nlnetlabs documentations for the full list of available commands.

• Import the module in your code

from unbound_console import RemoteControl

An asyncio implementation is available, use RemoteControlAsync instead.

• Configure the remote control client with tls support. You can also provide a unix socket unix_sock="/var/run/unbound-console.sock".

rc = RemoteControl(host="127.0.0.1", port=8953,
                   server_cert = "/etc/unbound/unbound_server.pem",
                   client_cert= "/etc/unbound/unbound_control.pem",
                   client_key= "/etc/unbound/unbound_control.key")

• Execute a command and get output

o = rc.send_command(cmd="status")
print(o)

Loading zone from YAML file

YAML zone definition example:

This requires installing unbound_console with yaml support

zone:
  name: home.
  type: static
  records:
    - "router.home. 86400 IN A 192.168.0.1"
    - "192.168.0.1 86400 IN PTR router.test."

Call load_zone with the yaml file to load-it in your unbound server.

o = rc.load_zone(zone_data='<yaml content>')
print(o)

Loading zone from "LocalZone" object

Example loading from a LocalZone object:

from unbound_console import LocalZone

zone = LocalZone(
    name="home",
    type="static",
    records=[
      "router.home. 86400 IN A 192.168.0.1",
      "192.168.0.1 86400 IN PTR router.test.",
    ],
)
o = rc.load_zone(zone_data=zone)
print(o)

Execute bulk command

domains_bulk = []
domains_bulk.append( "www.google.com always_nxdomain")

o = rc.send_command(cmd="local_zones", data_list=domains_bulk)
print(o)
