Initializer Command Line Reference

This is a reference document for the 128T Initializer command line interface. For a guide to basic usage, see the initialization section of the Manual Installation Guide.

Running the Initializer

To start the Initializer, run the initialize128t command.


initialize128t must always be run as the root user, or with sudo initialize128t. The Initializer will detect non-root usage and exit with this message:

You must run the Initializer as root.

Use the -h/--help flag to display help information for the initialize128t command line:

initialize128t --help

After a successful run, the initialize128t process will exit with a return code of 0. If any error was encountered during the operation, the return code will be non-zero.


128T must not be running during initialization. The Initializer will detect when 128T is running and exit with this message:

128T is running; cannot launch Initializer

To stop 128T, follow the steps shown in the Installation Guide.

Interactive Mode

Without any arguments, the Initializer will open a wizard interface to initialize 128T.


Follow the on-screen prompts to complete the initialization process. Step-by-step instructions for the Initializer wizard can be found in the Installation Guide.

Automated Mode

For more advanced use cases, preferences may be specified on the command line to perform initialization in an automated fashion, using the -p/--preferences option.

In this mode, no wizard will be displayed, but informational messages will be printed to the console as the Initializer is running.

$ cat /tmp/preferences.json
"node-name": "MyNode",
"node-ip": "",
"node-role": "combo",
"router-name": "MyRouter"

$ initialize128t --preferences /tmp/preferences.json
Did you know?

You can specify a preferences file with -p, but you can also pass the preferences directly on the command line. For example:

initialize128t -p \
'{"node-name": "MyNode", "node-role": "combo", "router-name": "MyRouter"}'

The specified preferences must be valid JSON (trailing commas are not allowed), and they must conform to the Initializer preferences file schema. See the full schema documentation for details.


-d, --dry-runSkip all steps that modify the system, e.g. downloading software or rebooting the system. This can be useful to validate a preference file without executing the operation specified in it.
-l LOG_LEVEL, --log-level LOG_LEVELChange the log level the Installer runs with. Must be one of ERROR, INFO, WARNING, DEBUG.
