The ethermaker package implements a set of tools and APIs for
generating MAC addresses.
- Generates MAC addresses.
- Describes MAC addresses.
- Written in pure Java 21 for safety and portability.
- High coverage test suite (100%, minus an unreachable private constructor).
- OSGi-ready
- JPMS-ready
- ISC license.
Usage: ethermaker [options] [command] [command options]
Options:
--verbose
Set the minimum logging verbosity level.
Default: info
Possible Values: [trace, debug, info, warn, error]
Use the "help" command to examine specific commands:
$ ethermaker help help.
Command-line arguments can be placed one per line into a file, and the file
can be referenced using the @ symbol:
$ echo help > file.txt
$ echo help >> file.txt
$ ethermaker @file.txt
Commands:
describe Describe MAC addresses
generate Generate MAC addresses
help Show detailed help messages for commands.
version Show the application version.
