Found this tweet and wanted to test it and record it for future reference.

I envision the most useful aspect is to t-shoot secure paging to personal devices in Medical Verticals. For example: Hospital System has an issue with secure paging being delayed. Where is the delay? Or is the transmission simply not being transmitted to the iOS device.

To obtain the UDID:

1. Connect iOS device via USB to MAC
2. Open up iTunes
3. Click the Serial Number Field on the Device Summary screen
4. UDID will be displayed

 

Start RVICTL -s <UDID>

m85077:~ wsmith3$ rvictl -s 2691c94e0ddf253525630d9ba382f5937a196b6f

Starting device 2691c94e0ddf253525630d9ba382f5937a196b6f [SUCCEEDED] with interface rvi0

Start TCPDUMP

m85077:~ wsmith3$ sudo tcpdump|wireshark -i rvi0

tcpdump: data link type PKTAP
