NAME
dns-ethers-import - generate DNS tables from /etc/ethers entries

SYNOPSIS
dns-ethers-import [ option... ] filename...
dns-ethers-import -Help
dns-ethers-import -VERSion

DESCRIPTION
The dns-ethers-import program is used to read your /etc/ethers file and produce a DNS-formatted database. This is used to maintain a database with the IP address and the MAC address in the same file. This helps find omissions and inconsistencies.

OPTIONS
The following options are understood:

-Domain name
    This option may be used to set the domain name in the generated file. Defaults to you system domain name, if set, otherwise ``example.com''.

-Help
    Provide some help with using the dns-ethers-import program.

-VERSion
    Print the version of the dns-ethers-import program being executed.

All other options will produce a diagnostic error. Options may be abbreviated, the minimum abbreviation is shown in upper-case. Options are case insensitive. Options and file names may be mixed arbitrarily on the command line.

EXIT STATUS
The dns-ethers-import command will exit with a status of 1 on any error. The dns-ethers-import command will only exit with a status of 0 if there are no errors.

EXAMPLE
If you have an /etc/ethers file which looks like this:
    2:7:1:f:b7:fb	mercury
    2:60:8c:2d:20:c4	venus
    8:0:20:79:1f:d	earth
    aa:0:4:0:86:53	mars
    8:0:2b:99:49:ad	jupiter
    0:40:10:56:43:57	saturn
    0:aa:0:69:7c:5b	neptune
    0:0:e8:a4:0:25	uranus
    8:0:9:d:2a:87	pluto
By using the following command
    % dns-ethers-import /etc/ethers ethers-tmp
    %
You will see an output file of the form
    $origin example.com.
    @		in	soa	example.com. hostmaster.example.com. (
    				3	; serial
    				10800	; refresh: 3 hours
    				1800	; retry: 30 minutes
    				604800	; expire: 1 week
    				86400 )	; minimum: 1 day
    mercury		ether	a	2:7:1:f:b7:fb
    venus		ether	a	2:60:8c:2d:20:c4
    earth		ether	a	8:0:20:79:1f:d
    mars		ether	a	aa:0:4:0:86:53
    jupiter		ether	a	8:0:2b:99:49:ad
    saturn		ether	a	0:40:10:56:43:57
    neptune		ether	a	0:aa:0:69:7c:5b
    uranus		ether	a	0:0:e8:a4:0:25
    pluto		ether	a	8:0:9:d:2a:87
You are expected to manually edit this into the rest of the database. You especially need to put sensable values into the SOA record.

See dns-ethers(1) for how to retrieve your /etc/ethers file once you have imported it.
