Googling a solution for this seems to always end with [numpy array_split](https://numpy.org/doc/stable/reference/generated/numpy.array_split.html)

onion-pi setup (reversed, WiFi as WAN)
View onion_pi.md

Walkthrough to setup a raspberry pi as an onion router. Pretty much like onion-pi but WiFi as WAN instead (bonus: no hostapd required).

This should (will?) be converted into an ansible playbook (or even pre-cooked image)

SDCard

  • Dump it on an sd card, eg:

It's quite easy after all. The settings are stored in /Library/Preferences/VMware Fusion/networking:
