RNDC-CONFGEN(8) BIND 9 RNDC-CONFGEN(8) NAME rndc-confgen - rndc key generation tool SYNOPSIS rndc-confgen [-a] [-A algorithm] [-b keysize] [-c keyfile] [-h] [-k key- name] [-p port] [-s address] [-t chrootdir] [-u user] DESCRIPTION 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. OPTIONS -a This option sets automatic rndc configuration, which creates a file /usr/local/etc/namedb/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 re- motely, run rndc-confgen without the -a option and set up rndc.conf and named.conf as directed. -A algorithm This option specifies the algorithm to use for the TSIG key. Avail- able choices are: hmac-md5, hmac-sha1, hmac-sha224, hmac-sha256, hmac-sha384, and hmac-sha512. The default is hmac-sha256. -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. -c keyfile This option is used with the -a option to specify an alternate loca- tion for rndc.key. -h This option prints a short summary of the options and arguments to rndc-confgen. -k keyname This option specifies the key name of the rndc authentication key. This must be a valid domain name and will be sanitized using the do- main name semantics. The default is rndc-key. -p port This option specifies the command channel port where named listens for connections from rndc. The default is 953. -q This option prevets printing the written path in automatic configu- ration mode. -s address This option specifies the IP address where named listens for com- mand-channel connections from rndc. The default is the loopback ad- dress 127.0.0.1. -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. -u user This option is used with the -a option to set the owner of the gen- erated rndc.key file. If -t is also specified, only the file in the chroot area has its owner changed. EXAMPLES 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 SEE ALSO rndc(8), rndc.conf(5), named(8), BIND 9 Administrator Reference Manual.
