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...

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

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...

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

Put:

ethtool -s eth0 wol g

Make executable:

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