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.

See the file man1/arglex.so.

See the file man1/exit.so.

EXAMPLE

If you have an /etc/ethers file which looks like this:


See the file man1/example.ethers.so.

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

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.
