[timpokorny]

Summary

The attached pcapng file contains a bunch of DIS traffic with the exercise id of 27. When I use the duplicator to replay it, the emitted packets have an exercise id of 1.

Environment and Logs

• Version: 1.2.0.5
• OS: Windows
• Attachments
  • Attached test file: wireshark-exerciseid-test.zip (contains pcapng file)

Reproduction Steps

• Open the given pcap file directly in Wireshark and filter for DIS traffic
• Check the exercise id listed on one of the Entity State PDUs, confirm it is 27
• Start a new Wireshark recording session
• Use the Duplicator to replay the file (bin/duplicator.sh --file <name> --replay)
• Inspect the re-captured traffic in Wireshark and notice that the exercise id has changed to 1
