1. INTRODUCTION
The Store and Forward (S&F) module allows PLAYER devices (Player ONE and Player ZERO)
to download remote audio content to local storage media (USB/uSD).
When it is active, it checks a remote location that hosts audio content on a daily basis, compares
it to the current content stored on local media (USB/uSD) and, if necessary (if differences are
detected), syncs the local content to make it an exact copy of the remote content. This is a safe
method of playing content on the device during working hours (during the day), storing it on local
media without the risks associated with real-time streaming.
The Store and Forward (S&F) utility for remotely synchronising music content uses the Rsync
(Remote Sync) tool.
This exemplified and orientative technical tutorial is intended for qualified IT personnel
only.
The third-party tools and procedures discussed in this manual are for information
purposes only, and no support queries will be answered in relation to them.
From now on in this tutorial, we will use the word PLAYER to refer both to Player ONE
and to Player ZERO models.

2. CREATE A VPS and SET IT UP WITH UBUNTU 22.04
2.1 Necessary tools
•Ubuntu 22.04
•VPS Provider
VPS is a virtual private server. It acts as an isolated server. Unlike shared hosting, it
works as if it were your own private server.
2.2 Necessary steps
The steps may differ depending on the contracted VPS provider, but the principle is
the same.
First of all, you need to have an active account and subscription with a VPS provider. To do
this:
1. Log in to your account and look for the "VPS" section.
2. Choose server size, amount of RAM, amount of storage space and amount of CPU.
3. Choose the operating system you want to install. In this case, we recommend Ubuntu
22.04.

4. In the time slot section, you must select the region in which you want to create your VPS.
5. In the Renewal Frequency section, you must select the desired option.
6. Verify that all information is correct and proceed to finalise the subscription.
7. Once subscribed, in the VPS configuration screen, you will be able to adjust network
settings, add additional storage, adjust security, etc. Configure these settings according
to your preferences and needs.
8. Once the VPS has been created, you will be able to access it through the provider's
console by entering your Ubuntu user details.
Recommended security tips to protect your VPS.
•Be sure to update and patch the server after the initial installation to keep it safe and
secure.
•Consider changing the SSH listening port, which defaults to 22.
•Change the password of the root user.

3. CONNECT TO VPS VIA SSH VIA PuTTY SOFTWARE
Once your VPS has been created and validated, the provider should provide you, via your
email account, with all the relevant information you will require to enter in the PuTTY
terminal:
•IPv4 address of the VPS.
•Name of the VPS.
•Administrator account.
•User.
•Password.
1. You can access the server through a command line terminal (on Linux or Mac) or using
third party software on Windows, we recommend PuTTY, which will be used in this
example.
2. Download the PuTTY software from its official website: https://www.putty.org/
3. Open PuTTY and in the "Host Name (or IP address)" section enter the IPv4 address of
the VPS you wish to connect to.
4. In the "Port" section, enter the communication port you have established, in this case we
will use the default port "22".
5. Select "SSH" as the connection type
6. Click "Open" to start the SSH session.

4. USER CREATION FOR STORE & FORWARD (S&F)
Now that we have our VPS up and running through the Putty terminal, let's create a new user
for the specific use of S&F.
It is important not to use the ADMIN user for the S&F implementation.
1. Before creating the new user, both for new versions of Linux and Ubuntu 22.04, we
must enter the following commands.
This procedure will restart your VPS and stop the SSH connection, so you will
need to reconnect via SSH.
sudo sh -c 'echo "HostKeyAlgorithms +ssh-rsa" >> /etc/ssh/sshd_config'
sudo sh -c 'echo "PubkeyAcceptedAlgorithms=+ssh-rsa" >> /etc/ssh/sshd_config'
sudo reboot
2. Shut down the PuTTY terminal and reconnect.
3. We create the specific user for Store & Forward. In this case, our user will be called "SAF".
sudo adduser --home /home/saf/ saf
4. Enter the new password for the SAF user.
5. Leave the following requested data (Full name, room number...) empty and press ENTER.
6. Press the "y" key to accept that the information is correct.
7. Enter the following commands in the terminal to change the user to SAF.
su saf
cd
mkdir sync

5. GENERATING SSH KEYS
1. We use the command ssh-keygen -m PEM to generate the keys and press ENTER
directly in response to each question (without typing anything).
2. Add the public keys to the authorised keys with the following command and then press
ENTER:
cat .ssh/id_rsa.pub >> .ssh/authorized_keys
3. You may view the private key that you need to enter in the Store and Forward
configuration page of the PLAYER:
cat .ssh/id_rsa
The private key that we must place in the S&F Module of our PLAYER is from "----
-BEGIN RSA..." dragging the cursor to the end, in "...PRIVATE KEY----".

7. STORE and FORWARD MODULE (Rsync)
Now that you have all the necessary data to implement the configuration, you will implement
it in the S&F module of your PLAYER.
1. “General” Section
•Enabled: In this section, activate the S&F Module (Rsync) by checking the box.
•Time: this is a very important point, as this is where the exact time of media
synchronisation between your SSH server and the PLAYER is configured so that
Rsync does the rest automatically.
Next, please press
It is very important that both the PLAYER and the SSH server have
continuous network access during media synchronisation. Otherwise, the LOG
module will show a synchronisation error message.

3. “Local Target” Section
In this section, you will indicate where Rsync will synchronise the files it receives
from the SSH server, either on a USB stick or SD card inserted in the PLAYER, in
FAT32 format.
a) Indicate the Path you wish to use, which you will later configure in the associated
PRESET1. In this example: usb://
b) PRESET 1 of our PLAYER is configured, so that the files from our USB or SD can
be played.
c) Press to save the Preset.

d) Restart the PLAYER.
The S&F module starts automatically and will start to dump and playback the
contents to the storage previously indicated.
Example of display in Player ONE (Player ZERO does not have a display
and must therefore be monitored via the Web App).
e) Lastly, check the PLAYER’s LOG to make sure that everything is correct.
From FileZilla it is possible to access the server folder to modify, add or
delete files. When you restart the PLAYER they will be synchronised as they are
in that folder.
