NAME¶

yadifa - utility for controlling yadifad(8)

SYNOPSIS¶

yadifa module [--config|-c configfile] [--server|-s host] [@host ] [--port|-p port] [-K key-name] [--version|-V] [-h] [--verbose|-v] [-t] command [[-q] zone]

DESCRIPTION¶

yadifa controls the operation of yadifad with its control module (ctrl), part of the YADIFA distribution from EURid vzw/asbl. The latest version of YADIFA can be found on:

http://www.yadifa.eu/download

yadifa communicates with a name server over a TCP connection. Messages are authenticated using a TSIG signature. The key is a secret shared between client and server. The key can be defined using a <key> section both in the client and the server. Additionally, the client accepts a full definition as a command line option. Note that using authentication is mandatory when using the control module.

For details about the key, see the manual or the TSIG section below.

MODULES¶

*

ctrl command Controls yadifad.

SIMPLE USAGE¶

For controlling yadifad a command can be:

OPTIONS¶

[--config|-c configfile]

Another config file will be used.

[--server|-s host] | [ @host ]

Host is the remote server to operate.

e.g.:

[--port|-p port]

Changes the DNS port. (default: 53)

[-K key-name]

Name of the key to be used for the controller. It needs to have been defined using a <key> section. (default: 'ctrl-key')

[-y hmac-algorithm:key-name:base64-key]

Definition of the key to be used for the controller.

[--verbose|-v]

Verbose output.

[--version|-V]

Show version information.

[--help|-h]

Show a help text

COMMANDS¶

[-t] cfgreload

Reload the settings from the configuration file on disk.

[-t] freeze [-q] zone

Disables dynamic updates to a zone.

[-t] freezeall [-q] zone

[-t] loglevel level

Sets the log level to the given value (0-15), 6 = INFO, 15 = ALL.

[-t] logreopen

Close all log files and reopens them.

[-t] notify

TSIG KEYS¶

TSIG keys are used for authentication of messages.
Their use is mandatory in the controller module.

Several digest algorithms are supported for the TSIG key:

Several methods can be used to generate the base64-encoded sequence of bytes for the secret:

*

%openssl rand -base64 32

*

%dd if=/dev/random count=1 bs=32 2>/dev/null|base64

*

%dd if=/dev/urandom count=1 bs=32 2>/dev/null|base64

e.g.:

#!/bin/sh
# TSIG key generation example
# can a
key_algorithm="hmac-sha256"
key_name="secretkey"
key_secret=$(openssl rand -base64 32)
if [ ! "x$1" == "x" ]
then
	key_name="$1"
fi
echo "# Encoded for the yadifa command-line: -y $key_algorithm:$key_name:$key_secret"
echo
echo "<key>"
echo "algorithm $key_algorithm"
echo "name $key_name"
echo "secret $key_secret"
echo "</key>"
