Packet Capture & Replay (StreamTo)

FibreCode Raw Sticks (FC612 for 100BASE-T1 and FC631 for 10BASE-T1L) bypass standard OS network stacks to provide raw Layer-2 Ethernet packet streaming with high-precision hardware timestamps.

The StreamTo command-line utility enables capturing traffic to standard pcapng files and replaying recorded captures onto automotive Ethernet links.

                └── streamto.exe

Open a terminal or command prompt in your architecture directory and test execution:

streamto.exe -h

sudo ./streamto -h

Record Raw Traffic to pcapng

Record raw automotive Ethernet packets directly into standard pcapng format with hardware timestamps:

streamto.exe pcap rec capture.pcapng

sudo ./streamto pcap rec capture.pcapng

Expected terminal output:

If Wireshark is installed, double-click capture.pcapng to inspect raw frame contents, VLAN tags, and hardware timestamps.

Replay pcapng Captures

Replay previously recorded traffic onto a 100BASE-T1 or 10BASE-T1L link using a FibreCode Raw Stick:

streamto.exe playpcap capture.pcapng -n <friendlyname>

sudo ./streamto playpcap capture.pcapng -n <friendlyname>

Parameters

• <filename>: Path to the .pcapng file to replay.
• -n <friendlyname>: Unique friendly name of the target FibreCode stick (configured via FC-Control).
• -d <index>: Alternatively, target device by numerical index (-d 0).
• -l: Continuous loop replay mode.
