F8 20A fuse blown on Ford Mondeo MK4 2L TDCI

Car stalled at the middle of the road. F8 20A fuse blown. Crappy Ford's user manual says: Powertrain control module. Brief and straight to the point.

After diagnosis it turned out the problem is on ECU Delphi DCM3.5 black connector line. Brown and grey connectors are OK. Test was very simple - 12V 40W lamp connected to F8 fuse contacts. When car door is opened, car activated and lamp glows, when door is shut, after a while PCM relay turns off the lamp. Something shorts F8 line when car is active. If you try ignition to crank car, lamp or fuse will burn. 

Looks like sophisticated electrical problem? Almost all connectors were checked but lamp glows. Finally air filter was removed, headlight was removed and broken wires were found. Modern engineering at it's best. Weak protection against rubbing and stupid location. Looks like one wire broke, shorted and burned few other wires. Here is the lesson: do not mess with electronics before checking physical lines.

Very fortunate that this damage happened on low speed in the city. On highway such thing may be lethal.  Overall Mondeo 4 is good car but engineering decisions on horn and ECU location, shitty wire isolation, absence of mechanical lock on passenger door, non-serviceable diodes in tail lights are annoying. Ave enshittification, morituri te salutant.

Privacy, telemetry, data collection

Any program that uses web UI via web-server may leak internal LAN IP-address of the device, for example IP Webcam for Android does this in Referrer. F12 > Dev Tools > Network > check what requests app makes. Any API is potential channel for leaking user data. Be cautions when using proprietary apps in sensitive environment. FOSS is better in such cases, else decompile, modify, rebuild.

CLI browsers are not safe browsers. Using w3m/lynx to “avoid JS” doesn’t make sense for anonymity; you’re trading usability and security for terminal UI. CLI inside a Tor-based system is safe way: Whonix, Tails (easiest).

Ordinary goofy will say that he has nothing to hide, but he do not take into account regime change, idiotic laws and limitations that may be in future... The less data you share, the better. Nobody has right to poke nose in your LAN, hardware, behavior, business...

GA-970A-DS3P FX wake on lan not working on Lubuntu

Looks like WOL is Enabled by default, if Erp Disabled, and MB is made solely for Windows, where WOL is enabled in driver. Enabled Power On By Mouse, Power On By Keyboard just in case... No lights on LAN port but 2.5W power draw... If CPU Turbo mode is enabled, 3.5W power draw...

Alternatives:

Option A — NetworkManager

Create a dispatcher script:

sudo nano /etc/NetworkManager/dispatcher.d/99-wol

Put:

#!/bin/sh

ethtool -s eth0 wol g

Make executable:

sudo chmod +x /etc/NetworkManager/dispatcher.d/99-wol

Reboot and check:

ethtool eth0 | grep Wake


Option B — systemd service

sudo nano /etc/systemd/system/wol.service
