Overview:

Events may arise that result in Content Filter platform oddities. Certain scenarios may require development investigation. Dev uses a variety of resources to identify reported issues. Details below cover how to provide more in-depth logs for troubleshooting.

Chrome OS has the capability to perform a Packet Capture. This can be completed using Developer Mode.

Packet Capture:

In Developer Mode enter the BASH shell (ctrl+alt+t > shell). Next type "packet_capture" to obtain details for outgoing packets.

The full command is: "packet_capture --device <interface>". Replace "<interface>" with name of interface to be captured.

Selecting Interface:

Use the command "connectivity show devices" to get the right interface.

This will provide a lot of output, including Wi-Fi details. The interface name can be found at the top of output, likely "mlan0" or "wlan".
