Openwrt-based router auth system

• Get a nim compiler: apt install nim build-essential
• Install needed dependencies: nimble install jester template
• Install LEDE/openwrt toolchain and build it for your router. Your target is make toolchain/gcc. See openwrt instructions.
• Clone this repository: git clone https://github.com/derlaft/fdi.git
• Edit build.sh, change openwrt toolchain path and architecture if needed.
• Run build: bash ./build.sh
• If everything is OK, you will get an executable named main. Place it, gateway.cfg and public/ directory to the router.
• On the router, you will need to install some packages: opkg install libpthread librt libopenssl libpcre
• Make sure you have enough RAM and disk space. I recommend at least 8Mb disk space. Install zram-swap package if you are low on mem.
• Place fdi.init to /etc/init.d/fdi to load service with start-up. /etcinit.d/fdi enable will load the service automatically.
• Configure /etc/config/firewall. See firewall.conf as example.
