Shore Connection

TelScope onboard on a ship communicates with a cloud based shore system. It exchanges data and receives updates of the operating system and the TelScope software. The TelScope servers onboard needs to communicate with our shore system, so the firewall must allow Telscope onboard to connect with the shore system in the cloud. The TelScope servers will then set up an (encrypted) VPN connection with our shore system and all access from our side is done through this VPN tunnel. Prior to the installation, you will receive the relevant IP addresses of the shore system. The network administrator onboard must be aware of the Telscope installation and will usually have to add some firewall rules as needed to allow the traffic between Telscope onboard and the shore system.

Accesing TelScope onboard

Telscope is a web application and needs to be accessible for the users onboard.

Telscope is available through a url on the form https://[IMO number] For smaller ships without IMO number, the url will be on the form https://[call sign] Telko automatically deploys https certificates in order to encrypt the communication between the servers and the clients.


Prior to the installation, Telko will add DNS records for this domain pointing to the local IP addresses of TelScopes server on board. The DNS service on board needs to  resolve this domain correctly.


Telscope is published on port 443. The firewall The Telscope servers needs to be accessible on the relevant networks.
