RTLS Replay

Replay recorded PCAP sessions from the RTLS server

Record

To record, run the server and simultaneously capture the packets into a PCAP file (e.g. using Wireshark or tcpdump). Make sure to filter so that only the appropriate packets are captured (e.g. filter by ip.addr == 169.254.193.203 && udp.port == 8282 on Wireshark, where 169.254.193.203 is whatever address you are sending packets to).

Playback

Update the default.json configuration in /config to the appropriate values.

This utility supports two modes of operation: UDP Unicast and UDP Multicast. Set the configuration file appropriately according to the mode-specific instructions below:

Unicast: A one-to-one sender-client UDP relationship. Your configuration will look similar to this. The address and port are the unicast address and port.

{
  "IP_ADDRESS": "127.0.0.1",
  "PORT": 8282,
  "USE_MULTICAST": false,
  "PCAP_FILENAME": "session.pcap",
  "DOES_LOOP": true
}

Multicast: A one-to-many sender-client UDP relationship. Your configuration will look similar to this. The address and port are the multicast address and port.

{
  "IP_ADDRESS": "234.5.6.7",
  "PORT": 8282,
  "USE_MULTICAST": true,
  "PCAP_FILENAME": "session.pcap",
  "DOES_LOOP": true
}

After your configuration files are set, then run the following commands in a terminal or command prompt:

npm install
npm start
