NMT (Noise Monitoring Terminals)

John Fawcett edited this page May 26, 2014 · 1 revision

NMT's represent the combination of hardware used to power ENRG services. It is composed of a small trailer, solar panels, battery backups, a 3g cellular modem, a really fancy microphone, some special hardware for performing noise analysis calculations, and a low-power consuming Windows XP Embedded machine.

When we setup the NMT's, we assign them a canonical ID following an existing scheme. Using that ID, we create a DNS record at our domain enrgnmt.com, such that, an NMT with the ID of 506 could be reached by sending requests to 506.enrgnmt.com.

Connecting to an NMT (Remote Desktop)

All NMT's are setup to accept RDP connections and the NMT's modem will forward all requests on the default RDP port (3389) to the local IP address that hosts the WindowsXP machine.

Warning: If you must connect via RDP (which, I advice you just use FTP or Telnet), ensure that the Remote Desktop Setting "Play sound on remote computer" is selected. If not, the machine will not recover its own audio capture device until it is restarted. All recordings will just be empty buffers.

Please ask John or Robert for account credentials.

Connecting to an NMT (Telnet)

All NMT's are configured to accept arbitrary TCP connections on port 10001 and generally follow the Telnet protocol. Performing the following command:

telnet 506.enrgnmt.com 10001

Will bring the user into B&K's P4441 terminal interface for configuring and reading data from the NMT.

Connecting to an NMT (FTP)

Pretty simple:
