yucahi is a WiFi scanner that shows 802.11 probes and beacons around.

The main goal is to show the networks the device has previously connected and as a result reveal the history of the places the user has connected and been to.

It shows the MAC address, vendor of network interface card, ESSID and calculates estimated distance with channel modulation and signal power. Interface turns to mode monitor automatically.

yucahi also organizes, uses colored output and sorts probes by time passed since last seen device.

It also offers a channel hopper that you can control (in seconds).

Finally, the information gathered is exported in JSON format for importing it with any front-end framework and displaying it in real time on an html page or adding it to any log aggregator (e.g. fluentd, logstash etc.)
