Run a simple repeated speed test every so often

Install

• Install Raspbian with Etcher.io
• touch ssh on boot vol
• plugin; connect to network; find IP via arp -i en0 -a or arp -i bridge100 -a if using bridge
• update hostname (/etc/hosts)
• update hostname file (/etc/hostname)
• sudo reboot
• sudo apt-get update && sudo apt-get upgrade
• Install Node (sudo apt-get install nodejs npm; you may need to add the nodesource builds: curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -)
• Install Avahi (bonjour: sudo apt-get install avahi-daemon)
• Forward port 80 to 3000: sudo iptables -t nat -I PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 3000 (via https://stackoverflow.com/questions/16573668/best-practices-when-running-node-js-with-port-80-ubuntu-linode and https://coderwall.com/p/plejka/forward-port-80-to-port-3000). You may want to add this without the sudo to /etc/rc.local to happen on boot.
• npm start

Set up wifi

https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md

1. Find networks: sudo iwlist wlan0 scan | grep ESSID
2. Generate PSK: wpa_passphrase "ssid" "pass"
3. Add wifi info: sudo nano /etc/wpa_supplicant/wpa_supplicant.conf:

   network={
       ssid="testing"
       psk=thepsk
   }
   

4. Reconfigure interface: wpa_cli -i wlan0 reconfigure
5. Successful iff ifconfig wlan0 has an IP.

Auto-start

I use a custom rc.local (see rc.local.deployme).
