Communications

First communications setup tests at Lousal.

Goal: Evaluate the communications conditions at Lousal site, install a device to log room temperature and humidity.

As there is no physical internet connection at the site, a GSM-based router was used to guarantee internet connection.

The router was installed in the guard house and a powerline link was established between the guard house and the logger device.

To communicate with the setup via a commercial supplier (NOS) a DDNS was created.

• An email was created ( setup.lousal@gmail.com )

• Created a DDNS account at no-ip (lousal.ddns.net)

• To access no-ip account (username: setup.lousal@gmail.com )

Second communications setup at Lousal.

The data collected from the first comunications setup lead to upgrade and change some aspects to ensure more redundancy and security.

Internet connection at the site, remains a GSM-based router setup via a commercial supplier (NOS - 938695713), that proven to be stable and reliable within acceptable values.

• Email ( setup.lousal@gmail.com )

• DDNS account at no-ip (lousal.ddns.net)

• To access no-ip account (username: setup.lousal@gmail.com )

A Raspberry Pi (Pi Guarda) was connected directly to the router allowing network debugging.

The connection from the guard house to the detector is made by using a powerline link to the detector's server.

The detector's server consistes in a desktop pc with 2 ethernet cards and running Fedora, this server as the funcion of bridging two separate networks, collect, prepare and send the detector's data to LIP.

These two separate networks were called WAN (connects the server to the router) and LAN (connects all controlers of the detector).

Configurations:

DDNS (lousal.ddns.net) config now points to the router.

Port 8080 (lousal.ddns.net:8080) gives access to the router management.

Virtual Servers were created on the router to permit direct ssh connection to Pi Guarda and the detector's server.

• ssh lousal.ddns.net -p 22100 - Server
• ssh lousal.ddns.net -p 22102 - Pi Guarda
