YADIFA(8) YADIFA YADIFA(8) NAME YADIFA is an utility for controlling YADIFAD SYNOPSIS yadifa module [--config|-c configfile] [--server|-s host] [@host ] [--port|-p port] [-K key-name] [--version|-V] [-h] [--verbose|-v] [-t] com- mand [[-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 defini- tion 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: NORMAL USE CASE yadifa ctrl @server -t command -q argument FRIENDLIER USE CASE yadifa ctrl @server command argument ctrl Module used for controlling yadifad server Is the IP address of the name server to control. If no "server" ar- gument is given yadifa.rc will be checked. command Is the command to be invoked argument Depending the command this can be e.g. a domain name. EXAMPLE yadifa ctrl @127.0.0.1 freeze somedomain.eu OPTIONS [--config|-c configfile] Another config file will be used. [--server|-s host] | [ @host ] Host is the remote server to operate. e.g.: yadifa --server 192.0.2.1 yadifa @192.0.2.1 By default the DNS port is used. A port can be specified along with the IP address: e.g.: yadifa --server "192.0.2.1 port 5353" yadifa @"192.0.2.1 port 5353" [--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. hmac-algorithm Optional, can be: hmac-md5, hmac-sha1, hmac-sha224, hmac-256, hmac-384, hmac-512. (default: hmac-md5) key-name is the fqdn of the key. base64-key is a base64 encoding of the key bytes. e.g.: -y hmac-sha1:our-shared-secret:ThisIsASecretShared= -y our-shared-secret:ThisIsASecretShared= [--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 Disables dynamic updates to every zone currently loaded. [-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 Sends notifies to slaves of these zones. [-t] querylog [enable|disable] Sets the log for queries on or off (default: enable). [-t] reload [-q] zone Triggers the loading of the zone file(s) if the serial number is incremented. [-t] shutdown Shuts down the server. [-t] sync [-q] [zone] [clean] Write the zone to disk and optionally cleans up the journal. [-t] thaw [-q] [zone] Enables dynamic updates to a zone. [-t] thawall Enables dynamic updates to every zone. [-t] unfreeze [-q] [zone] Enables dynamic updates to a zone. [-t] unfreezeall Enables dynamic updates to every zone. [-t] zonecfgreload [-q zone] Reload the zone information in the configuration file and reload the zone file(s) with increased serial number. 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: * hmac-md5 * hmac-sha1 * hmac-sha224 * hmac-sha256 * hmac-sha384 * hmac-sha512 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>" FILES yadifa The name server remote client. ${SYSCONFDIR}/yadifa.conf default yadifa configuration file. ${HOME}/.yadifa.rc default rcfile. yadifa.conf.5 Configuration man page for yadifa. yadifa.rc.5 Configuration man page for yadifa. yadifa.8 This man page.
