pynab_cli

A collection of small command line tools for Pynab-running Nabaztag rabbits that have been revived using the Raspberry Pi Zero W-powered Tag:tag:tag card.

nabaztag

A script to send packets to the rabbit’s nabd daemon, according to the Pynab protocol.

	pi@Nabaztag:~ $ nabaztag -h
	Usage: nabaztag [-g | -e | -l | -m | -s | -w | -p LEFT.RIGHT | -r | -v | -c COMMANDFILE] [HOST]
		Talk to rabbit HOST (default: localhost)
		 no option :	get state
			-h :	this usage help
			-g :	get gestalt status
			-e :	execute ears test
			-l :	execute LEDs test
			-m :	monitor asr/button/ears/rfid events
			-s :	go to sleep
			-w :	wake up
			-p :	rotate ears to position LEFT.RIGHT
			-r :	rotate ears to random position
			-v :	display virtual rabbit (running in Docker on HOST)
			-c :	execute given JSON COMMANDFILE

Examples of JSON command files are provided in the json directory.
This script should be usable on a non-rabbit OS, if it provides the nc (netcat) command.

Note:
Talking to a remote rabbit is possible only if the nabd socket on this rabbit has been enabled for public access.

tagtagtag-sound

A script to get/set the rabbit’s Tag:tag:tag sound card low/high volume levels.

	pi@Nabaztag:~ $ tagtagtag-sound -h
	Usage: tagtagtag-sound [-t | -T] [-m low | -M high] [-p]
		 no option :	get sound volume levels
			-h :	this usage help
			-t :	handle volume for Nabaztag
			-T :	handle volume for Nabaztag:tag (default)
			-m :	set minimum volume level
			-M :	set maximum volume level
			-p :	patch/unpatch ADC mixer (to eliminate NFC card interference)

backup/restore_pynab_db

Scripts to backup and restore the rabbit’s Pynab PostgreSQL database.

	pi@Nabaztag:~ $ backup_pynab_db -h
	Usage: backup_pynab_db [-u DB_USER] [-d DB_NAME] [-b DB_BACKUP_FILE]
		Backup (as user DB_USER) PostgreSQL database DB_NAME to file DB_BACKUP_FILE
		defaults: DB_USER=postgres DB_NAME=pynab DB_BACKUP_FILE=pynab.db.sql
	
	pi@Nabaztag:~ $ restore_pynab_db -h
	Usage: restore_pynab_db [-u DB_USER] [-b DB_BACKUP_FILE]
		Restore (as user DB_USER) PostgreSQL database from file DB_BACKUP_FILE
		defaults: DB_USER=postgres DB_BACKUP_FILE=pynab.db.sql

Note:
Backup can be done on the fly (while the rabbit’s Pynab services are running). According to PostgreSQL documentation, the backup is consistent (based on a ‘snapshot’ of the database).
On the other hand restore must be done without concurrent accesses to the database (so that it can be re-created). Pynab services must therefore be stopped beforehand and restarted after the backup (the script takes care of this).

pynab

A script to manage Pynab services.

	pi@Nabaztag:~ $ pynab -h
	Usage: pynab [-status | -start | -stop | -restart | -local | -public | -log [NUM]]
		no option :	show status of Pynab services
		    -help :	this usage help
		   -start :	start Pynab services
		    -stop :	stop Pynab services
		 -restart :	restart Pynab services
		  -status :	show status of Pynab services
		   -local :	restrict nabd socket to local access
		  -public :	open nabd socket to public access
		     -log :	show log tails (last NUM lines) for Pynab daemons

Note:
By default, rabbit’s nabd socket is restricted to local access (from the rabbit itself).
Opening it to public access makes it accessible from other hosts. This is a potential security risk if the rabbit is not on a local network protected by a firewall.
