NAME

6       YADIFA is an utility for controlling YADIFAD
7

SYNOPSIS

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

DESCRIPTION

14       yadifa  controls  the  operation  of  yadifad  with  its control module
15       (ctrl), part of the YADIFA distribution from EURid vzw/asbl. The latest
16       version of YADIFA can be found on:
17                            http://www.yadifa.eu/download

20       yadifa communicates with a name server over a TCP connection.  Messages
21       are authenticated using a TSIG signature. The key is  a  secret  shared
22       between  client  and server.  The key can be defined using a <key> sec‐
23       tion both in the client and the server.  Additionally, the  client  ac‐
24       cepts  a full definition as a command line option.  Note that using au‐
25       thentication is mandatory when using the control module.
26
27       For details about the key, see the manual or the TSIG section below.

90
91              key-name

TSIG KEYS

164       TSIG keys are used for authentication of messages.
165       Their use is mandatory in the controller module.
166
167       Several digest algorithms are supported for the TSIG key:
168
169              *      hmac-md5
170
171              *      hmac-sha1
172
173              *      hmac-sha224
174
175              *      hmac-sha256
176
177              *      hmac-sha384
178
179              *      hmac-sha512
180
181       Several  methods can be used to generate the base64-encoded sequence of
182       bytes for the secret:
183
184       *      %openssl rand -base64 32
185
186       *      %dd if=/dev/random count=1 bs=32 2>/dev/null|base64
187
188       *      %dd if=/dev/urandom count=1 bs=32 2>/dev/null|base64
189
190       e.g.:
191
192       #!/bin/sh
193       # TSIG key generation example
194       # can a
195       key_algorithm="hmac-sha256"
196       key_name="secretkey"
197       key_secret=$(openssl rand -base64 32)
198       if [ ! "x$1" == "x" ]
199       then
200            key_name="$1"
201       fi
202
203       echo "# Encoded for the yadifa command-line: -y $key_algorithm:$key_name:$key_secret"
204       echo
205       echo "<key>"
206       echo "algorithm $key_algorithm"
207       echo "name $key_name"
208       echo "secret $key_secret"
209       echo "</key>"
