Lisa LCD
59
In all cases the Lisa initiates the connection to the outside, requiring permission for outbound TCP
traffic only. Only when Telnet is used from outside the local network, an inbound TCP connection on port
23 of the Lisa should be allowed. See
8.7.1
Ports used for device-related activities (configuration, monitoring, etc.)
The Lisa performs a number of functions that require information to flow over the network, such as
retrieving its configuration, its schedule, playlists, as well sending monitoring data, etc. In all cases the
Lisa makes a connection to a remote location, for which the address (the URL) is configured in the
device settings.
By reading the settings from the device, you can extract the ports that are used by the device for these
different functions (see
Extracting the port from a URL
). When Streamit platforms are used, this is not
required, the ports that are used are listed below.
Note that all mentioned ports need to be open for all functions to operate properly. Only opening the
configuration port will not be sufficient for, e.g., the monitoring to work.
Streamit Device portal
When the Streamit device portal is used as provisioning platform, connections will be made with the
following servers:
Device portal (devices.streamit.eu)
Port 9999 – for configuration update and schedule update.
Port 4444 – for monitoring.
Port 80 – for configuration update*
* Only required for some devices: devices running old software (will ‘redirect’ device to port 9999), or
devices configured to use port 80 for configuration update. Streamit Device portal can deliver the
configuration for a Lisa via port 80, the Lisa needs to be configured with a configuration update URL that
points to port 80 instead of port 9999. This can be done using
corresponding command (see
).
Streamit webserver (streamit.eu)
Port 80 – for software update, used as default software update resource
Streamit Audio Distribution Platform (ADP)
When the Streamit ADP is used as provisioning platform, connections will be made with the following
servers:
Streamit ADP (adp2.streamit.eu)
Port 80 - for configuration update, schedule update and playlist update (download of playlist
update file)
