9 yadifa module [--config|-c configfile] [--server|-s host] [@host ]
10 [--port|-p port] [-K key-name] [--version|-V] [-h] [--verbose|-v] [-t]
11 command [[-q] zone]
12
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
18 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 For details about the key, see the manual or the TSIG section below.

30 * ctrl command Controls yadifad.
31
33 For controlling yadifad a command can be:
34 NORMAL USE CASE
36 yadifa ctrl @server -t command -q argument
37 FRIENDLIER USE CASE
39 yadifa ctrl @server command argument
40 ctrl Module used for controlling yadifad
42 server Is the IP address of the name server to control. If no "server"
44 argument is given yadifa.rc will be checked.
45 command Is the command to be invoked
47 argument Depending the command this can be e.g. a domain name.
49 EXAMPLE
51 yadifa ctrl @127.0.0.1 freeze somedomain.eu
52
54 [--config|-c configfile]
55 Another config file will be used.
56 [--server|-s host] | [ @host ]
58 Host is the remote server to operate.
59 e.g.:
61 yadifa --server 192.0.2.1
64 yadifa @192.0.2.1
66 By default the DNS port is used. A port can be specified along
68 with the IP address:
69 e.g.:
71 yadifa --server "192.0.2.1 port 5353"
74 yadifa @"192.0.2.1 port 5353"
76 [--port|-p port]
78 Changes the DNS port. (default: 53)
79 [-K key-name]
81 Name of the key to be used for the controller. It needs to have
82 been defined using a <key> section. (default: 'ctrl-key')
83 [-y hmac-algorithm:key-name:base64-key]
85 Definition of the key to be used for the controller.
86 hmac-algorithm
88 Optional, can be: hmac-md5, hmac-sha1, hmac-sha224,
89 hmac-256, hmac-384, hmac-512. (default: hmac-md5)
90 key-name
92 is the fqdn of the key.
93 base64-key
95 is a base64 encoding of the key bytes.
96 e.g.:
98 -y hmac-sha1:our-shared-secret:ThisIsASecretShared=
101 -y our-shared-secret:ThisIsASecretShared=
103 [--verbose|-v]
105 Verbose output.
106 [--version|-V]

145 [-t] thaw [-q] [zone]
147 Enables dynamic updates to a zone.
148 [-t] thawall
150 Enables dynamic updates to every zone.
151 [-t] unfreeze [-q] [zone]
153 Enables dynamic updates to a zone.
154 [-t] unfreezeall

161 reload the zone file(s) with increased serial number.
162
164 TSIG keys are used for authentication of messages.
165 Their use is mandatory in the controller module.
166 Several digest algorithms are supported for the TSIG key:
168 * hmac-md5
170 * hmac-sha1
172 * hmac-sha224
174 * hmac-sha256
176 * hmac-sha384
178 * hmac-sha512
180 Several methods can be used to generate the base64-encoded sequence of
182 bytes for the secret:
183 * %openssl rand -base64 32
185 * %dd if=/dev/random count=1 bs=32 2>/dev/null|base64
187 * %dd if=/dev/urandom count=1 bs=32 2>/dev/null|base64
189 e.g.:
191 #!/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 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>"
