rndc-confgen: invalid argument --
Usage:
rndc-confgen [-a] [-b bits] [-c keyfile] [-k keyname] [-p port] [-s addr] [-t chrootdir] [-u user]
-a: generate just the key clause and write it to keyfile (/etc/bind/rndc.key)
-A alg: algorithm (default hmac-sha256)
-b bits: from 1 through 512, default 256; total length of the secret
-c keyfile: specify an alternate key file (requires -a)
-k keyname: the name as it will be used in named.conf and rndc.conf
-p port: the port named will listen on and rndc will connect to
-q: suppress printing written key path
-s addr: the address to which rndc should connect
-t chrootdir: write a keyfile in chrootdir as well (requires -a)
-u user: set the keyfile owner to "user" (requires -a)
Options (11)
| Option | Description | Source |
|---|
-a | This option sets automatic rndc <#std-iscman-rndc> configuration, which creates a file /etc/bind/rndc.key that is read by both rndc <#std-iscman-rndc> and named <#std-iscman-named> on startup. | help + man |
-A alg: | This option specifies the algorithm to use for the TSIG key. | help + man |
-b bits: | This option specifies the size of the authentication key in bits. | help + man |
-c keyfile: | This option is used with the -a option to specify an alternate location for rndc.key. | help + man |
-k keyname: | This option specifies the key name of the rndc <#std-iscman-rndc> authentication key. | help + man |
-p port: | This option specifies the command channel port where named <#std-iscman-named> listens for connections from rndc <#std-iscman-rndc>. | help + man |
-q | This option prevets printing the written path in automatic configuration mode. | help + man |
-s addr: | This option specifies the IP address where named <#std-iscman-named> listens for command-channel connections from rndc <#std-iscman-rndc>. | help + man |
-t chrootdir: | This option is used with the -a option to specify a directory where named <#std-iscman-named> runs chrooted. | help + man |
-u user: | This option is used with the -a option to set the owner of the generated rndc.key file. | help + man |
-h | This option prints a short summary of the options and arguments to rndc-confgen. (in the manual page but not in --help) | man |
