Web server (port 80) — 2026-11-01

host/kindle-rootfs/usr/local/bin/kindle-web.py + OpenRC service kindle-web (runlevel default). Python 3 standard library only (apk add python3), no framework.

URL	Content
/	status page: kernel, uptime, load, memory, disk, SoC temperature, battery, WiFi signal (refreshes every 10 s)
/status.json	the same data as JSON
anything else	static files from /srv/www (a /srv/www/index.html replaces the status page)

Runs as the unprivileged user www; OpenRC grants only CAP_NET_BIND_SERVICE (capabilities="^cap_net_bind_service") so it can bind port 80. Request log goes to syslog (logger -t kindle-web).

Install on a fresh system:

apk add python3
tar -C host/kindle-rootfs -cf - usr/local/bin/kindle-web.py etc/init.d/kindle-web | ssh root@kindle8.local 'tar -xf - -C /'
ssh root@kindle8.local 'addgroup -S www; adduser -S -D -H -h /srv/www -s /sbin/nologin -G www www; rc-update add kindle-web default; rc-service kindle-web start'

Notes

• The SoC sensor is the thermal zone of type imx_thermal_zone (zone 1). Zone 0 is the battery, and reads 10× too low because bd71815_get_temp() returns whole °C where the power-supply ABI expects tenths (see docs/battery.md). TODO: fix in the kernel patch.
• avahi is restricted to wlan0 (allow-interfaces=wlan0) so kindle8.local never resolves to the USB address when the cable is unplugged. Over USB use 192.168.7.2.
