VoIP Ethernet Capture FreeSBC

Capturing Ethernet traffic

• Connect to the FreeSBC using a ssh connection
• Start tbx_cli_tools_remote (type "tbx_cli_tools_remote")
• Connect to the tbrouter application
• Start capture using the 'p' key (lowercase p), leave default parameters and press 'enter'
• Stop capture using the 'P' key (uppercase P)

Retrieve Ethernet captures

Ethernet capture files (pcap/Wireshark compatible) are locate here:

 /lib/tb/toolpack/tbrouter/pcap

Note: There can be multiple capture files per capture session (for example, on systems with 10Gbps network devices, because Ethernet packets on these devices are spread to multiple packets processing/capture cores)
