VoIP Ethernet Capture FreeSBC

Revision as of 09:23, 22 March 2018 by Abrassard (talk | contribs) (Fixed issues with this procedure, was not precise enough, was pointing to tbx_cli_remote which does not exist (it's tbx_cli_tools_remote!!!))

Applies to version(s): v3.0

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)
