Wireshark/tshark onboard for deeper troubleshooting on OSX? | |
Monitor Mode (disruptive) for 802.11 Management and Control Frames which contain much richer data about signal, capabilities, other nodes etc.. | |
Note: Testing for more specific/useful frames but right now we just want access to some richer data that can be easily manipulated when a user or network has issues i.e. when "/usr/sbin/system_profiler SPAirPortDataType" and "/System/Library/PrivateFrameworks/Apple80211.framework/Resources/airport" are not enough (as per https://gist.github.com/donalod/ba467ffdb2a2531cd13e ) | |
/usr/local/bin/tshark -i en1 -I -L | |
Data link types of interface en1 when in monitor mode (use option -y to set): | |
IEEE802_11_RADIO (802.11 plus radiotap header) | |
PPI (Per-Packet Information) | |
