It can be used as a convenient alternative to writing the \fI\%rndc.conf\fP file and the corresponding \fBcontrols\fP and \fBkey\fP statements in \fI\%named.conf\fP by hand. Alternatively, it can be run with the \fI\%\-a\fP option to set up a \fBrndc.key\fP file and avoid the need for a \fI\%rndc.conf\fP file and a \fBcontrols\fP statement altogether. .SH OPTIONS .INDENT 0.0 .TP .B \-a This option sets automatic \fI\%rndc\fP configuration, which creates a file \fB/etc/rndc.key\fP that is read by both \fI\%rndc\fP and \fI\%named\fP on startup. The \fBrndc.key\fP file defines a default command channel and authentication key allowing \fI\%rndc\fP to communicate with \fI\%named\fP on the local host with no further configuration. .sp If a more elaborate configuration than that generated by \fI\%rndc\-confgen \-a\fP is required, for example if rndc is to be used remotely, run \fBrndc\-confgen\fP without the \fI\%\-a\fP option and set up \fI\%rndc.conf\fP and \fI\%named.conf\fP as directed. .UNINDENT .INDENT 0.0 .TP .B \-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. .UNINDENT .INDENT 0.0 .TP .B \-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. .UNINDENT .INDENT 0.0 .TP .B \-c keyfile This option is used with the \fI\%\-a\fP option to specify an alternate location for \fBrndc.key\fP\&. .UNINDENT .INDENT 0.0 .TP .B \-h This option prints a short summary of the options and arguments to \fBrndc\-confgen\fP\&. .UNINDENT .INDENT 0.0 .TP .B \-k keyname This option specifies the key name of the \fI\%rndc\fP authentication key. This must be a valid domain name. The default is \fBrndc\-key\fP\&. .UNINDENT .INDENT 0.0 .TP .B \-p port This option specifies the command channel port where \fI\%named\fP listens for connections from \fI\%rndc\fP\&. The default is 953. .UNINDENT .INDENT 0.0 .TP .B \-q This option prevets printing the written path in automatic configuration mode. .UNINDENT .INDENT 0.0 .TP .B \-s address This option specifies the IP address where \fI\%named\fP listens for command\-channel connections from \fI\%rndc\fP\&. The default is the loopback address 127.0.0.1. .UNINDENT .INDENT 0.0 .TP .B \-t chrootdir This option is used with the \fI\%\-a\fP option to specify a directory where \fI\%named\fP runs chrooted. An additional copy of the \fBrndc.key\fP is written relative to this directory, so that it is found by the chrooted \fI\%named\fP\&. .UNINDENT .INDENT 0.0 .TP .B \-u user This option is used with the \fI\%\-a\fP option to set the owner of the generated \fBrndc.key\fP file. If \fI\%\-t\fP is also specified, only the file in the chroot area has its owner changed. .UNINDENT .SH EXAMPLES .sp To allow \fI\%rndc\fP to be used with no manual configuration, run: .sp \fBrndc\-confgen \-a\fP .sp To print a sample \fI\%rndc.conf\fP file and the corresponding \fBcontrols\fP and \fBkey\fP statements to be manually inserted into \fI\%named.conf\fP, run: .sp \fBrndc\-confgen\fP .SH SEE ALSO .sp \fI\%rndc(8)\fP, \fI\%rndc.conf(5)\fP, \fI\%named(8)\fP, BIND 9 Administrator Reference Manual. .SH AUTHOR Internet Systems Consortium .SH COPYRIGHT 2024, Internet Systems Consortium .\" Generated by docutils manpage writer. .
