OSX WIFI Scanning

A collection of scripts to automate wifi scanning and signal strength capturing.

Installation

This is just a bunch of little bash scripts, so aside from that (and common GNU tools) the main dependencies are:

• airport (the OSX scanning utility)
• xsltproc (to process the XML from airport)
• feedgnuplot and gnuplot (only required if you want to plot)

Usage

Run a scan (using airport to scan):

$ ./scan

Scan only specific networks:

$ ./scan "Network1" "Network2"
2023-11-19T21:16:42+0800	1700399802	Network1	a0:a0:a0:a0:a0:01	11	-36
2023-11-19T21:16:42+0800	1700399802	Network2	a0:a0:a0:a0:a0:11	36	-61

Repeatedly scan specific networks:

$ ./monitor "Network1" "Network2"
2023-11-19T21:16:42+0800	1700399802	Network1	a0:a0:a0:a0:a0:01	11	-36

2023-11-19T21:16:45+0800	1700399805	Network1	a0:a0:a0:a0:a0:01	11	-37

Repeatedly scan, plotting in the terminal:

$ ./monitor "Network1" | ./plot --terminal "dumb ansi $COLUMNS,$((LINES-4))"
