Raspberry Pi 3 headless wifi AP

this is a quick checklist, detailed description provided in the urls

• write raspbian ISO image with pv/dd to microSD
• mount ROOT and boot
• touch /boot/ssh to enable ssh (important new req)
• follow below steps described here in details
• move /etc/init.d/rc2.d/K*ssh to S*ssh
• edit /etc/wpa_supplicant/wpa_supplicant.conf and provide network {} section with AP SSID and password RPi should connect to
• boot RPi
• use nmap -sP <existing-network>/24 to find the IP, ssh to user pi@<found-address> and default rasbpian password
• change the pi password (and possibly create own user)
• install hostapd & udhcpd
• prepare appropriate configs as described here:

• /etc/network/interfaces
• /etc/hostapd/hostapd.conf
• /etc/udhcpd.conf
• update /etc/default/udhcpd & /etc/default/hostapd to enable deamons
• service enable udhcpd & hostapd
• update the udev rules to keep persist the wlan* network interfaces
• /etc/iptables* (with an appropriate convention)

other things:

• install docker for RPi ;)
• install docker cross compile ARM environment on your PC/Mac to enable faster building of custom/trusted binaries

all below possibly as a docker instances with separated config volume

• move the hostapd config to docker
• configure openvpn as a docker
• install shairport to enable apple AirPlay
• install as a docker dnsmasq, BIND or PowerDNS
