Generate a report of all VPN connects, system sleeps, and "location-awareness" messages for the last seven days. "location-awareness" log messages are generated by ControlPlane actions that are triggered based on my geographical location (home or work).

vpn-report.sh

#!/bin/sh

reportfile=/vpn-reports/`date +%Y-%m-%d`.txt

echo "**** VPN report generated @ `date` ****" > $reportfile
syslog -k Sender pppd \
    -k Message "L2TP connection established." \
    -o -k Message "L2TP disconnected" \
    -o -k Sender location-awareness \
    -k Time ge -7d \
    -o -k Message Seq "System Sleep" \
    -k Sender kernel >> $reportfile

• Needs to be run as root (or maybe admin user) to fetch all messages
• The "System Sleep" message comes from my Wi-Fi driver (AirPort_Brcm43xx) so that may not appear on all machines (although it's a standard Retina MacBook Pro so it might be quite ubiquitous)

The "location-awareness" ControlPlane actions are one-liner shell scripts looking like this:

logger -t location-awareness "Arrived at home"
