titleSet NAT and Qualify

From the command line issue the command

psql -Upostgres asgi_cc -c"UPDATE devices SET nat=true, qualify='yes';"

If it works you should see a number of devices updated.

titleFix "The license file /license.bin is not valid for this server." error

This issue happens when a VM is licensed then cloned or coppied and the license file no longer matches the systems ID.

To correct login and issue the commands:

rm /data/ring/licenses/license.bin

titleHunter | Network Metrics | Bandwidth

Bandwidth is the amount of information that can be transmitted, measured in bits per second (bps), or some multiple thereof. When monitoring, you need to distinguish between the nominal data link/Ethernet bit rate, the throughput of a link at Layer 3, and the throughput available to an application.

Bandwidth for audio depends on the sampling frequency (Hertz) and bit depth of each sample. For example, telecommunications links are based on 64 Kbps channels. This was derived through the following calculation:

The voice frequency range is 4000 Hz. This must be sampled at twice the rate to ensure an accurate representation of the original analog waveform.
The sample size is 1 byte (or 8 bits). Therefore, 8 KHz x 8 bits = 64 Kbps.
For VoIP, bandwidth requirements for voice calling can vary, but allowing 100 Kbps per call upstream and downstream should be sufficient in most cases.

Bandwidth required for video is determined by image resolution (number of pixels), color depth, and the frame rate, measured in frames per second (fps).
