preship provisioning tool

The PreShip provision Tool is used to communicate the location of the encrypted apk files .

Flash tablets
Run encryption if desired
plug in a USB/audio adapter in the USB?Audio jack (or micro USB Adapter )
connect a USB Ethernet dongle into the USB adapter.

Tablet will discover the PreShip Provision Tool and get the following :

Location of the server running an rsync daemon, user name & password if needed and path to the tablet software files:
eg rsync://git@ntn-mstevens-01.ntn.com:59144/tablet/1.47/BTUpdates/ and the git user password.
QR Code data from a QR Code that the PreShip provision Tool has prescanned.

The ntn-mstevens-01.ntn.com has rsync configured to run as a daemon (linux) for the above example, the /etc/rsyncd.conf file holds the following :

pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsync.log
port = 59144

[tablet]
   path = /home/mstevens/tablet
   comment = tablet packages
   read only = yes
   uid = mstevens
   gid = domain^users
   list = yes
   auth users = rsyncclient,tablet,git
   secrets file = /etc/rsyncd.secrets

and the /etc/rsyncd.secrets file contains name:password pairs, one per line. Note that since this password is in plain text, the file MUST be owned by only root, and readable by only root (chmod 600 /etc/rsyncd.secrets).
