.. rndc-confgen - rndc key generation tool rndc-confgen [-a] [-A algorithm] [-b keysize] [-c keyfile] [-h] [-k keyname] [-p port] [-s address] [-t chrootdir] [-u user] rndc-confgen generates configuration files for \%rndc. It can be used as a convenient alternative to writing the \%rndc.conf file and the corresponding controls and key statements in \%named.conf by hand. Alternatively, it can be run with the \%-a option to set up a rndc.key file and avoid the need for a \%rndc.conf file and a controls statement altogether. NDENT 0.0

-a This option sets automatic \%rndc configuration, which creates a file @sysconfdir@/rndc.key that is read by both \%rndc and \%named on startup. The rndc.key file defines a default command channel and authentication key allowing \%rndc to communicate with \%named on the local host with no further configuration. If a more elaborate configuration than that generated by \%rndc-confgen -a is required, for example if rndc is to be used remotely, run rndc-confgen without the \%-a option and set up \%rndc.conf and \%named.conf as directed. NINDENT NDENT 0.0

-A algorithm This option specifies the algorithm to use for the TSIG key. Available choices are: hmac-md5, hmac-sha1, hmac-sha224, hmac-sha256, hmac-sha384, and hmac-sha512. The default is hmac-sha256. NINDENT NDENT 0.0

-b keysize This option specifies the size of the authentication key in bits. The size must be between 1 and 512 bits; the default is the hash size. NINDENT NDENT 0.0

-c keyfile This option is used with the \%-a option to specify an alternate location for rndc.key. NINDENT NDENT 0.0

-h This option prints a short summary of the options and arguments to rndc-confgen. NINDENT NDENT 0.0

-k keyname This option specifies the key name of the \%rndc authentication key. This must be a valid domain name. The default is rndc-key. NINDENT NDENT 0.0

-p port This option specifies the command channel port where \%named listens for connections from \%rndc. The default is 953. NINDENT NDENT 0.0

-q This option prevets printing the written path in automatic configuration mode. NINDENT NDENT 0.0

-s address This option specifies the IP address where \%named listens for command-channel connections from \%rndc. The default is the loopback address 127.0.0.1. NINDENT NDENT 0.0

-t chrootdir This option is used with the \%-a option to specify a directory where \%named runs chrooted. An additional copy of the rndc.key is written relative to this directory, so that it is found by the chrooted \%named. NINDENT NDENT 0.0

-u user This option is used with the \%-a option to set the owner of the generated rndc.key file. If \%-t is also specified, only the file in the chroot area has its owner changed. NINDENT

To allow \%rndc to be used with no manual configuration, run: rndc-confgen -a To print a sample \%rndc.conf file and the corresponding controls and key statements to be manually inserted into \%named.conf, run: rndc-confgen \%rndc(8), \%rndc.conf(5), \%named(8), BIND 9 Administrator Reference Manual.
