 edit `/etc/oxidized/config` and modify `rest: 127.0.0.1:8888` to `rest: 0.0.0.0:8888`. This will bind port 8888 to all interfaces, and expose the port so that it could be accessed externally. [(Issue #445)](https://github.com/ytti/oxidized/issues/445)

 To initialize a default configuration in your home directory `~/.config/oxidized/config`, simply run `oxidized` once. If you don't further configure anything from the output and source sections, it'll extend the examples on a subsequent `oxidized` execution. This is useful to see what options for a specific source or output backend are available.
 
 You can set the env variable `OXIDIZED_HOME` to change its home directory.
