Privacy, telemetry, data collection

https://librewolf.net/

LibreWolf — privacy enhanced firefox gets much better results on https://coveryourtracks.eff.org

sudo apt update && sudo apt install extrepo -y

sudo extrepo enable librewolf && sudo extrepo update librewolf

sudo apt update && sudo apt install librewolf -y

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.

sudo ufw enable

sudo apt install tor

torsocks --version

sudo systemctl enable tor      // start on boot

sudo systemctl start tor          // start now

sudo systemctl status tor       // check if running

torsocks curl https://check.torproject.org

CLI browsers are not safe browsers:

sudo apt install lynx // may leak real IP if misconfigured

sudo apt install w3m // may leak real IP if misconfigured

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

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...

KTorrent not seeding and not downloading

Forward only 6881 for tcp and udp in router or choose another port. Paste it for TCP, mtp, DHT, apply and other ports will be changed automatically.

sudo ufw allow 6881/udp

sudo ufw reload

netstat -plunt | grep ktorrent

Shrink disk size partition in terminal with parted resize

The Victory Lap: 851GB shrinked drive (Stable), 323GB 4256-sector slop (Webcam Trash), screaming shrinked 978GB 2005-sector zombie (Torrent Sacrifice). Successfully built "Post-Apocalyptic" Storage Array out of pure e-waste. It's chatty, it spams errors - but it's moving 110MB/s and cost $0.

KGet download and upload limit not working

nano ~/.bashrc

alias slowget='aria2c -c -x 16 -s 16 --file-allocation=prealloc --max-download-limit=1024K -o'

source ~/.bashrc

cd /desired/folder

slowget "file_0.avi" "URL"


If download fails:

slowget "file_0.avi" "NEW_URL" // to resume


Alternatives for using KGet:

E: Package 'trickle' has no installation candidate


sudo apt install firejail // 28.5 MB

firejail --net=eth0 --bandwidth=kget:1500:1500 kget


sudo wondershaper eth0 1500 1500 // NIC limit

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

No truth - just approximation

What we’ve been circling around is **not new at all**. Different pieces of this worldview appeared **independently** across cultures, usually when thinkers hit the same wall you’re hitting now: “certainty collapses, dogma looks violent, truth looks provisional.”

Here’s a rough historical map of *when humans first articulated these ideas*.
