INSTALLING AND CONNECTING

3.1 INSTALLATION, ASSEMBLY, AND VENTILATION The MSMP has been specially developed so that it can be used both as a desktop unit and for installation in a 19″ rack, filling a third of a rack unit (LDTICARK rack shelf for standard rack cabinets optionally available). In professional systems, it should preferably be installed in the same rack as the audio sources. Ventilation is not necessary due to the very low consumption. However, care must be taken to ensure that it is not exposed to extremely high temperatures and that the environment is as dry and dust-free as possible.
3.2 CONNECTING TO THE MAINS SUPPLY AND SWITCHING ON THE DEVICE The MSMP is supplied with DC voltage via its external mains adapter: mains adapter 100­240 VAC and 50­60 Hz. This mains adapter is equipped with various interchangeable connectors, suitable for the American, European, British, and Chinese systems. The working environment must be dry and completely dust-free. The device must not be exposed to water or splashes of water. Do not place any containers with liquids or naked flames, such as candles, on the device. If any intervention and/or switching on/off of the device is necessary, the device must always be disconnected from the mains beforehand. There are no elements inside the device that may be manipulated by the user. To avoid unwanted humming noises, the mains cable must be prevented from coming into contact with the shielded audio cables that transport the signal.
3.3 AUDIO OUTPUT CONNECTIONS The MSMP has 1 unbalanced stereo output on its rear panel. The signal output sockets are of the type 2 × RCA and 1 × 3.5 mm stereo mini jack.
3.4 ETHERNET PORT FOR CONFIGURATION AND INTERNET CONNECTION An RJ-45 socket allows the device to be connected to an Ethernet network or directly (point-to-point) to a computer. This connection makes it possible to access content on the Internet and to configure the device using a web browser installed on the computer, which accesses the IP address of the MSMP, making the web application embedded in the device visible. You can find more information on this in the MSMP web application manual.
3.5 WI-FI INTERFACE FOR CONFIGURATION AND INTERNET CONNECTION A Wi-Fi interface allows the device to be connected to a Wi-Fi network or directly (point-to-point) to a computer via Wi-Fi. This connection makes it possible to access content on the Internet and to configure the device using a web browser installed on the computer, which accesses the IP address of the MSMP, making the web application embedded in the device visible. You can find more information on this in the MSMP web application manual.
3.6 GPI PORTS FOR REMOTE CONTROL The MSMP has 2 GPI inputs on the back for control. These inputs can be connected to an external device (e.g. contact closure) and assigned to a function of the MSMP: · Loading and playback of previously configured audio content · Access of a preset · Playback of audio content with priority via the music programme · Control via the transport bar (PLAY/PAUSE, STOP, etc.) · Internal initiation for interaction with other player services (e.g. scripts)

7.2.3 EVENTS There are three events available: two of which are initiated by the GPI ports (via potential-free external contact closure, connected to the GPI ports on the back of the device) and the third by silence detection. Both event types can be configured on the EVENTS page. Selecting the corresponding tab takes you to the configuration of an event.
Attention: Please note that for an event to function properly, it must be enabled in the currently selected preset.

7.2.3.1 GPI EVENTS There are two GPI events: GPI1 and GPI2. These can be configured so that they are initiated in different ways and carry out independent actions.
Illustration: Configuration of a GPI, Conditions
· Conditions: GPI Trigger: Normally open or normally closed contact; to specify initiation based on contact closure or contact release

ENGLISH

· Actions tab: Action that the device should carry out after GPI activation; There are various options and eventtypes: INTERNAL: Internal pulse; useful for initiating actions within a script. PRESET RECALL: Access of a preset. Select the preset that you want to load by activating the GPI. TRANSPORT CONTROL: Control of the current playback, STOP, PLAY, PREV/RW, NEXT/FW, PLAY/ PAUSE. LOAD & PLAY SOURCE: Loading and playing of a source. The source must be defined in the “Source path/url” field. PRIORITY SOURCE: Playback of a source with priority over the programme’s audio content. The source defined in the “Source path/url” field attenuates the source currently being played (programme’s audio content). Once the prioritised audio playback is finished, the programme audio content is played again, whereby the volume is slowly increased until the previous level is reached again. If you select the HOLD option, the source defined in the “Source path/url” field remains prioritised AS LONG AS the triggering pulse stops (GPI direct/reverse, depending on the definition in the “Source” tab). If you select the PULSE option, the source defined in the “Source path/url” field remains prioritised for the time period (in seconds) entered in the “Time” field. The Retrigger option allows the priority event to be re-initiated without having to wait until it has elapsed; the timer is then restarted. A prioritised event can be useful for playing back announcements, previously saved messages, emergency messages, etc. You can find more information on the topic of priorities in the chapter All about priorities.
7.2.3.2 EVENT INITIATED BY SILENCE DETECTION ­ SILENCE The MSMP has a special event, the SILENCE or silence detection event: no real analogue audio signal is present at the device outputs. This event allows the player to continue playing media if the programme audio content being played ends or is interrupted for any reason, which can occasionally happen if problems occur (interruption of the Internet connection, accidental disconnection of the mains cable, incorrect files, etc.): “The show must go on”.
Illustration: Configuration of the silence event

ENGLISH

· Source tab: Waiting time or trigger threshold (detection time). Set the permitted silence duration (without audio signal) before activating the event here.
· Target tab: Select the action that the MSMP should perform after the waiting time has elapsed. Internal: Internal pulse. Useful for initiating actions within a script Preset recall: Access of a preset Select the preset that you would like to access by activating the silence event. Load & Play Source: Loading and playing of a source. The source must be defined in the “Source path/url” field. Recommendation: Configure the loading of local audio content (stored on USB or uSD) as an action to ensure that audio content is always available, regardless of any incidents that occur outside the player in the network connection. Make sure two things are done when accessing presets: ensure that the audio address saved in the selected preset is a local address (e.g. usb://), and that the overwriting of the player status(Play Status) is enabled in the preset so that the PLAY option is set. As a result, this will force the playback of a local storage medium, ensuring that the music programme continues.
7.2.4 CALENDAR The Calendar page allows you to configure events that are initiated by the calendar. A calendar event performs a specific action, for example, loading a prioritised announcement, according to configurable parameters: date, time, repetitions, etc.
1
2
Illustration: Example for a calendar event configuration.
1 The MSMP has 24 calendar events, all of which are fully configurable. The standard designations are: C01, C02 … C24. Clicking on one of these designations takes you to the configuration of the specific calendar event. The calendar event designations shown here can be changed as part of the respective configuration. After you have saved this setting in the calendar event, you must refresh the browser page (F5) in order to display the changes.
28

ENGLISH

2 The configurable parameters of the individual calendar events are summarised in three tabs: · General: Activation/deactivation of calendar events and name · Source: Start and end date, start and end time, as well as conditions for the repetition of an event · Target: Action to be performed when the event is initiated.
Attention: Before you configure calendar events, you should ensure that the time zone is configured correctly: System/Name and time.
Figure: Configuration of name and time

7.2.4.2 SOURCE The SOURCE tab is used to set the time/date parameters in order to initiate an event and the conditions for its repetition.
Illustration: Configuration of a calendar, General
7.2.4.3 DATE AND TIME INTERVAL Defines the date and time when the event starts and, if applicable, the date and time when it ends. · Start date: Date of the start of the event. This field is optional. If no specific date is selected, the
event begins on the day on which the changes are applied. If you select a date that is before the current date, the event applies from the day on which the changes are applied. · Start time: Time of the start of the event. This field is mandatory. If a repeat condition has been defined, this is the time at which the event is initiated for the first time on each day. · Duration: Duration or validity of the calendar event. Allows the selection of time periods for the duration of the calendar event. FOREVER (forever): Default value. The calendar event has no end date. CUSTOM END DATE: End of the calendar event. Allows you to set a date and time for the last initiation
of the calendar event, regardless of the repeat conditions. 30

ENGLISH

Illustration: Example of an interval
7.2.4.3.1 WEEKLY REPETITION Weekly template or days of the week on which the calendar event should repeat at the time specified under “Start Time”. If, for example, the days from Monday to Friday are selected (working days), the configured event is not initiated on Saturdays and Sundays (weekends).
Illustration: Example of a weekly template
If at least one day of the week is not selected, the calendar event is never initiated. The same applies if you configure an event that is to be initiated on a specific day of the week, but this day is not selected in the weekly template.
7.2.4.3.2 DAILY REPETITION Daily repetitions. This option is deselected by default. If it is activated, a drop-down window opens to configure the repeat conditions: · Interval: Repetition interval. Specifies the time intervals at which the calendar event is to be
repeated from the start time (“Start Time”). · Times: Number of repetitions. Specifies how often the calendar event should repeat at the intervals
specified under “Interval”. The first everyday initiation of the event does not count as a repetition. This means that if you want an event to be initiated twice a day, the value 1 must be entered under “Times” (the first initiation + 1 repetition). The value to be entered here must always be equal to or greater than 1.
31

ENGLISH

Illustration: Example of a daily repetition
· “The event will finish at” specifies the time at which the calendar event will be executed for the last time on each day. This parameter cannot be configured (read-only). It is only intended as a guide and should help the user to optimise the configuration of the “Interval” and “Times” parameters.
7.2.4.4 TARGET An action to be performed each time the calendar event is initiated.
Illustration: Example of a calendar event, target
These can be the following types of action: · Internal: Internal impulse (no action is executed directly, but actions can be initiated via scripts) · Preset recall: Loading of a preset · Transport control: Press a button on the transport bar: STOP, PLAY, PREV, NEXT, PLAY/PAUSE · Load & Play source: Loading and playing of a source · Priority source: Playback of a priority source. The prioritised source overwrites the source, which is
currently playing. Once the prioritised message/announcement has ended, playback of the previous source is resumed. 32

ENGLISH

7.2.4.5 ALL ABOUT PRIORITIES Calendar events have a lower priority than events that are initiated via GPI. Different priority levels can therefore be defined. In retail, for example, calendar events can be used to initiate special offer announcements, while GPI events are used to initiate emergency announcements, e.g. for evacuation. In contrast, a higher index determines the priority if two calendar events are initiated simultaneously. For example, the event CALENDAR02 could be configured so that an announcement is repeated every hour, while CALENDAR03 should repeat another announcement every two hours (both events have identical start times). In this case, the announcements would alternate every hour, as CALENDAR03 has priority over CALENDAR02. If a calendar event occurs while another is already in playback, the event that occurred last overwrites the one in playback, regardless of the index of both events.
7.2.4.6 PRACTICAL EXAMPLE FOR THE CONFIGURATION OF A CALENDAR EVENT A retail company with opening hours from 10:00 a.m. to 8:00 p.m., from Monday to Friday, would occassionally like to have background music and broadcast announcements play for customers during in-between times. · Background music: The same audio stream should always be played from 9:45 a.m. to 8:00 p.m.
No audio content should be heard in the shop from 8:00 p.m. · Announcements: The closing time should be announced every day 15 minutes before the shop closes
(pre-recorded announcement). A reminder should be played five minutes before the end of the programme. · Advertising campaigns: From 15 December to 15 January, there will be a special Christmas campaign announcing special offers (pre-recorded announcement). This announcement will be repeated every 30 minutes during the campaign.
These requirements can be met in different ways. In our example, we try to illustrate the most important features of the calendar events in a simple way.
33

ENGLISH

7.2.4.6.1 CALENDAR FOR BACKGROUND MUSIC Two calendar events are created: one to load and play the stream, the second to pause playback. The calendar is activated and given a unique name.
As no specific start date is specified, we leave the “START DATE” field at its default value so that the event is active as soon as the changes are applied. The time is known (9:45 a.m.) and should be reproduced daily without an end date(FOREVER). Since the event is to be repeated from Monday to Friday, the corresponding days are selected in the weekly template.
34

ENGLISH

The action of loading and playing the specified stream is configured.
The configuration of the calendar event that is to stop the playback of the background music is carried out in the same way, with the difference that the action to be carried out now consists of stopping (STOP) the playback. The calendar event is then given a different name and a different start time.
35

36

ENGLISH

ENGLISH

7.2.4.6.2 CALENDAR FOR CLOSING TIME ANNOUNCEMENTS The closing time should be announced every day 15 minutes before closing (pre-recorded announcement). A reminder should be played five minutes before closing.
The announcement should be made twice each day: 15 minutes before closing (7:45 p.m.) and again 5 minutes before closing time (7:55 p.m.). A calendar event must therefore be configured that is repeated once, 10 minutes after it was initiated for the first time. The repetitions (REPEAT) are set up successfully, and the Interval and Time parameters are configured successfully.
37

ENGLISH

Finally, the announcement saved on the SD card (“mmc://…”) is prioritised and initiated. 38

ENGLISH

7.2.4.7 CALENDAR FOR THE CHRISTMAS CAMPAIGN
As a specific calendar period is specified in this case (15/12/21 to 15/01/22), an end date must be configured. This is done by selecting CUSTOM END DATE and correctly configuring the End date and End time parameters.
39

ENGLISH

As far as the repeats are concerned, the announcement should be made every 30 minutes, and we know that the shop closes at 8:00 p.m. As no more audio content is broadcast at 8:00 p.m., we set the number of repetitions so that the event is carried out for the last time 30 minutes before closing time.
40

ENGLISH

Finally, the announcement saved on the USB card (“usb://…”) is prioritised and initiated.
7.2.5 CLOUD DISC SYNC The CLOUD DISK SYNC module enables the device to download external audio content to local storage media (USB/uSD). If this module is activated, it carries out a daily check of a remote location where the audio content is hosted, compares it with the current content of the local storage media (USB/uSD) and, if necessary (if differences are detected), synchronises the local content so that it becomes an exact copy of the external content. This is a secure method of playing content stored on a local storage medium during the device’s operating hours (during the day) without having to take the risks of receiving streaming in real time.
SSH server
Figure: Folder synchronisation with Store and Forward (rsync)
The MSMP offers the option of synchronising via the service provider Store and Forward (rsync). 7.2.6 STORE AND FORWARD (RSYNC) The Store and Forward module enables the content of the USB/uSD device with a folder hosted on a remote server to be synchronised on a daily basis. It is also used in conjunction with the reset mode Load preset1 to automatically play this content. This service uses the synchronisation tool rsync(Remote Sync).

7.2.7 SCRIPTS/LUA A script is a simple programme, a file with commands, written by the user in the programming language LUA (https://www.lua.org/). Each script can be seen as a kind of script that the player is supposed to realise, i.e. a series of preprogrammed tasks to be performed as soon as the corresponding trigger is received.
1 2

4
Illustration: Example of a script
1 20 scripts can be created for the MSMP; each of which is fully configurable. The default names are: S01, S02…S20. Clicking on a name takes you to the configuration page of the corresponding script. The script names shown here can be changed on the configuration page. After saving this script setting, you must refresh the browser page (F5) to see the changes made. 2 Useful information on script configuration and Lua reference manual 3 Configurable script parameters:
· Name: Name that the user specifies for the script. This name appears in the header of the Scripts/LUA page.
· Enable: Enable or disable the script · Trigger: Impulse to execute the script. There are various options for triggering a script or the
automation of tasks:
45

ENGLISH

Figure: Available trigger pulses
ON BOOT: Start-up tasks can be configured during device activation. ON EVENT: With activation of a GPI event (GPI1 or GPI2), in addition to the silence detection event
(SILENCE) ON PRESET: After loading a preset. One of the 20 presets must be selected, which then activates
the script. ON CALENDAR: When a calendar event is initiated. One of the 24 calendar events must be selected,
which in turn initiates the script. ON CLOUD DISK SYNC: With successful synchronisation with a remote server (synchronisation result
“OK”). It must be specified: rsync. ON LAN: When the local network (LAN) is detected as either available or unavailable ON WAN: When Internet access (WAN) is detected as either available or unavailable ON MMC: When a uSD card is connected/disconnected and correctly recognised by the player ON USB: When a USB device is connected/disconnected and correctly recognised by the player ON ERROR: When an error occurs, which is listed in the form of a code in the “Error code”. You will
find a table of error codes in the programming library (appendix for programmers). LUA SOURCE CODE: The text of the script is entered in this field. 4 Buttons: Buttons for executing and stopping the script. The START button executes the script immediately without the programmed pulse having to occur. In order for the changes to be applied, the script must be saved before pressing this button. The button is useful for carrying out tests. The STOP button stops script execution. These functions are particularly useful when programming scripts in order to check the actions executed by the individual scripts and to clean up the respective code.
Figure: Buttons for the execution of scripts
46

ENGLISH

· Script Status: Shows the status of the script: RUNNING (flashing) when the script is being executed or STOPPED (permanently lit) when it has finished or stopped executing.
· Script Output: Output/return value of the script. Output messages can be written to then appear on the display. Helpful for cleaning up scripts.
Illustration: Example of the return value of a script
· Documents for programmers: Links (in blue) are shown in the player for viewing purposes (Internet connection required): LUA: Manual of the LUA programming language Device: LUA library of the MSMP (appendix for programmers). The objects, functions, and parameters of the library are explained here. Interface between LUA and the player’s firmware using the JSON protocol. LuaSocket: Documentation of the LuaSocket library. cjson: Documentation of the LUA CJSON module. This offers JSON support for LUA.
The following chapters show some examples of simple scripts. Remember that the script is a very powerful tool for programming and personalising the MSMP, because a single script can perform different tasks, which can be linked together and which depend on different circumstances; it can thus introduce genuine logic and intelligence into your workflow. The only limit is your imagination!
47

ENGLISH

7.2.7.1 EXAMPLE SCRIPT02: Automatic playback of the content of the uSD card as soon as it is inserted There are applications in which the local storage medium changes depending on the user. In a gym, for example, each trainer changes the music according to their specific training session. In other words, each trainer connects their own USB storage device or uSD card to play their specific audio content. This could be automated so that users simply insert their storage medium into the player, at which point playback begins automatically. This would prevent improper handling and/or save the user from having to read the operating instructions. In the following example, a script is used to automate the playback of the content of a uSD card as soon as it is inserted. Such a script could also be written for the automatic playback of the content of a USB storage medium, in which case you would only have to change the trigger and the URL.
· require “PLAYER” · ep = PLAYER.new() · ep.PLAYER_open{url=”mmc://”}
48

ENGLISH

7.2.7.2 EXAMPLE SCRIPT04: Playing Internet radio after restoring the Internet connection The following script accesses a preset as soon as an available Internet connection (WAN) is detected. This can be interesting when used with the silence detection event: The player is playing an Internet radio programme and suddenly loses the connection to the radio station due to a network problem. After a few seconds without audio playback, the silence detection event is activated, and the player starts playing the content of the uSD card (backup music). However, playback of the previously broadcast radio programme should continue automatically as soon as the Internet connection is restored.
· require “PLAYER” · ep = PLAYER.new() · ep.PLAYER_open({preset=2})

ENGLISH

7.4.4 USB/MMC SETTINGS Used to display the storage space used in the local storage media and to manage the encryption function if there is a need to secure the musical content stored on the uSD card, USB device, or similar for reasons of security or data protection. This allows for data to be protected if the local storage medium were to be stolen, as it can only be read by the device that encrypted it.
Figure: Encryption concept
The encryption concept works as follows: 1. The storage medium is formatted by the device during encryption. This process deletesthe entire
memory content of the uSD card or USB device. 2. The process may take a few minutes. 3. Once the process is complete, the text “NO FILES” is displayed under “Disc usage”, which means that
formatting has been successfully completed and there are no more audio files on the external medium. 4. The external medium is now ready to download content using the “Cloud disk sync”­ Store and Forward (rsync) tool.
If this function is disabled, the process described above must be restarted to re-enable it.
63

ENGLISH

Please note the following considerations regarding the encryption function: · The encryption process is destructive, as formatting the external medium deletes all files stored on it. · If this function is enabled, any other external medium (uSD or USB) that is inserted into the corres-
ponding slot and does not containthe encryption keys will be encrypted, i.e. all files stored on it will be deleted. As a result, only content that is stored on a medium encrypted by the player itself can be played. · The external storage medium cannot be read by any other device (this also applies to other MSMPs) that does not have the encryption codes. · The content can be read by the device that has encrypted it, provided that the encryption option is not changed. This means that as soon as the encryption function is blocked, it is no longer active on the player, and it can therefore read any external storage medium. However, it loses the codes for external media that were previously encrypted and can therefore no longer play their content.
It is a tool that can be used with another tool to synchronise content: Store and Forward (rsync). If the external storage medium is encrypted, it cannot be read or written to (by copying content) by any device, e.g. a computer. This means that the only device that can copy content from this medium is the player that has encrypted it. The “Store and Forward” (rsync) tool makes this possible.
Illustration: USB/MMC Settings
· Encryption enabled: Enables or disables encryption of the USB or uSD storage medium. If the activation is saved, the player encrypts the storage medium the next time it is inserted into the device or when the device is restarted.

ENGLISH

· Apply Encrypt now: The storage medium is encrypted immediately. · Disk Usage: Storage capacity of the medium (MB) and used storage space (%) on the uSD card or USB
device. If no storage medium is found, the message “NO DISK” appears. 7.4.5 REGISTER The log file(REGISTER) makes detailed monitoring of the player’s activities possible. This information can be helpful for troubleshooting, tracking the device’s activities, checking correct programming, etc. The log lines contain information about the actions performed by the player, as well as errors that have occurred and/or messages that have been issued, in each case with the time (when the various events occurred). A list of the log lines reported by the device is provided on the “Tab” page. A device’s log file is updated daily and with every restart. This deletes the previous log lines. However, a copy of the log file can be saved on a local storage medium every day. This allows the user to view the recordings for several days.
Illustration: Register
· Backup to: Enables daily saving of copies of the log file on a local storage medium. The path must be specified for this (e.g. “usb://registers”).
7.4.6 REBOOT This page allows you to restart the player from the web application. Click on PERFORM REBOOT to force the device to restart.

7.5 CONFIGURATION OF AN SSH SERVER FOR STORE AND FORWARD (RSYNC) The MSMP’s Cloud Disk Sync, Store and Forward module enables the device to download external audio content to local storage media (USB/uSD). If it is activated, it carries out a daily check of a remote location where the audio content is hosted, compares it with the current content of the local storage media (USB/uSD) and, if necessary (if differences are detected), synchronises the local content so that it becomes an exact copy of the external content. This is a secure method of playing content stored on a local storage medium during the operating hours of the device (during the day) without having to take the risks of receiving streaming in real time. The Store and Forward service for synchronising remotely stored musical content uses the rsync (Remote Sync) tool for this purpose. These instructions show an example of how to configure an SSH server using Linux (Ubuntu Desktop 18.04.2 LTS). It is important that all devices, servers, and clients are connected to the same network (LAN/intranet).
Important note: For a cloud-based configuration of Store and Forward, a virtual private server (VPS) would have to be rented in order to obtain a public IP address and access the SSH server via the Internet.

7.5.1 CONTENT GROUPS
A content group is a group of devices that synchronise the same audio content using the Store and Forward service. A separate user must be created for each content group. A device that has been assigned to a specific content group can thus only access the content assigned to this group and not other content. This procedure is for safety reasons. Each content group manages its own access code to access the content assigned to it on the server, where all the music, announcements, voice messages, etc. are hosted.
Several connections can be assigned to each content group or user at the same time. The maximum possible number of simultaneous connections depends on the hardware performance (server).
This allows us to create as many content groups or users in Linux as we want to manage content (e.g. music folders).
/user_shop/adds/campaign1

CONTENT GROUP 1 User: Shop Key: key1

/user_bars/music/Pop

SSH server

/user_hotels/backgnd/folder1

CONTENT GROUP 2 User: Bars Key: key2

CONTENT GROUP 3 User: Hotels Key: key3

Illustration: Content groups

For easy configuration, it is possible to create just one user so that all devices can access their content with the same user name and key. The security level is skipped in this configuration. An experienced user could configure Store and Forward using the player’s built-in web server
(by changing the assigned folder) to access any content on the SSH server since the key is known.

For professional applications where an SSH server hosts content for different companies, creating a user for each content group is recommended. However, if the end user creates their own content, a single user is sufficient.

7.5.2 INSTALLING SSH UNDER LINUX
Firstly, the SSH package must be installed under Linux. Open a terminal and enter the following: sudo apt-get install ssh

You can open a terminal with the following shortcut: {ctrl+ alt + T}.
7.5.3 CREATING USERS UNDER LINUX
As many users are created as there are content groups to manage. To add a new user, enter the following: sudo adduser <new_user_name&gt In this case, <new_user_name> stands for the username that you want to give to the content group, for example: sudo adduser hotels

69

ENGLISH

Now log in as the new user: su <user_name&gt and enter the password you set in the previous step. In this example:
7.5.4 GENERATING THE SSH KEY Before creating the SSH keys, you must go to the new user’s home folder with: cd Then use the following command to create the key pair and click Enter for each question that appears: ssh-keygen -m PEM
70

ENGLISH

Add the public keys to the authorised keys with the following command: cat .ssh/id_rsa.pub >> .ssh/ authorized_keys
Display the private key that you need to enter on the Store and Forward configuration page of the player: cat .ssh/id_rsa

7.5.5 ADDING AUDIO CONTENT TO THE SSH SERVER

The next step is to store the correct audio content on the SSH server for each specific user or content group. A folder is thus created in the root directory of each content group: sudo cp -r <path_with_ content> <path_to_place_it&gt

In this example, the audio content is copied to the following directory:

sudo cp -r /home/ldsystems/sandf/hotels /home/hotels

71

ENGLISH

Please note that the entire audio content of all content groups or users is stored in the /home/ldsystems/sandf/ directory and organised in different folders.
Copy the newly created directory /home/hotels/hotels. This is the folder in which the audio content is stored on the host and which must be copied to the MSMP’s S&F configuration page. 7.5.6 ADAPTING THE SSH KEYS TO THE LATEST UBUNTU VERSION Newer Linux versions have made the RSA algorithms used by PLAYERs outdated. PLAYER Store & Forward LOG displays an error message as follows:
For this reason, the server configuration must be changed so that PLAYER RSA can be executed. To solve this quickly, we recommend that you use the following command in the server terminal: sudo sh -c ‘echo “HostKeyAlgorithms +ssh-rsa” >> /etc/ssh/sshd_config’ sudo sh -c ,echo ,,PubkeyAcceptedAlgorithms=+ssh-rsa” >> /etc/ssh/sshd_config` sudo systemctl restart sshd 7.5.7 CONFIGURING THE REMOTE SOURCE ON THE PLAYER Finally, the remote source (SSH server) can be configured in the S&F application. 72

ENGLISH

· Host: The IP address of the SSH server. To check, enter the following in the terminal: ifconfig
· Port: Port of the SSH server. By default 22. · Folder: Directory on the SSH server with the audio content to be synchronised · Username: Username or name of the content group · Private key: The key generated for the user or content group
This configuration is the same for all devices in the content group. Repeat steps 3 to 6 for each content group that you want to configure for Store and Forward.
