Portal icon menu settings icon general icon network icon Network: download a TCP dump

Use a TCP dump to investigate communication issues between the Octalarm alarm dialler and your network.

  • Open Settings.
  • Go to Network: internet check.
  • Select Download file.

Your computer saves the TCP dump as a compressed file in the Downloads folder. The file contains up to 5 MB of recent network traffic from the Octalarm alarm dialler’s Ethernet and GSM connections. Extract the file with an open source zip programme such as 7-Zip. You can then open and analyse the extracted files with, for example, Wireshark.

Note: The TCP dump does not include data packets to or from TCP port 80.

Good to know: For other Network: internet check settings, remote setup works in the same way as setup on the dialler itself. See Settings | General | Network: internet check for further explanation.
