geoWifi

 

https://danielnovello.github.io/geoWifi/

Lightweight CLI application that scans for available SSID's and if specified SSID is found, trigger a policy in Jamf (Potentailly anything you want to happen)

Note: Does not need to be connected to any Wifi to function. It scans available Wifi SSID's

Manual usage:

sudo ./geoWifi SSID JAMFTRIGGER

If SSID found

Example Alert script in Jamf

#!/bin/bash
/Library/Application\ Support/JAMF/bin/jamfHelper.app/Contents/MacOS/jamfHelper -title "Jamf Security" -windowType hud -description "Jamf Security" -description "You are entering a probibited Area" &

Create a Persistant LaunchDaemon

NOTE: This has not been tested long term. Not sure of the CPU usage over long periods of time.

• Create a script (make it executable) and copy it your chosen location

  #!/bin/bash
  /PATHTOAPP SSID JAMFTRIGGER
  

• Create a LaunchDaemon Plist and copy to /Library/LaunchDaemons (Ammend with the location of your script) Example in Repo Fix the Permissions:

  sudo chown root /Library/LaunchDaemons/com.djquazzi.geowifi.plist
  sudo chgrp wheel /Library/LaunchDaemons/com.djquazzi.geowifi.plist
  

• Run the LaunchDaemon

  sudo launchctl load -w /Library/LaunchDaemons/com.djquazzi.geowifi.plist
  

  All logs in /private/var/log/geowifi.log You might want to scrub the log every now and again.

  Why not use built in method and script? (Legacy command)

   /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -s
  

  The above command using the airport command does work, however testing the airport command and geoWifi along side each other, it is clear that for reliabilty, accuracy and performance geoWifi wins when used with a persistant LaunchDaemon
