dns-ethers-import -Help
dns-ethers-import -VERSion


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.


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''.

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

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.


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.


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

                                 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.
