-To get the windows product key execute with admin privileges: wmic path softwarelicensingservice get OA3xOriginalProductKey

-Use mitmf or ettercap to start mitm then use ferret to capture cookies (ferret -i eth0)
  use hamster to set session cookies and then in browser set the proxy settings to manual giving the address
  provided by hamster and finally open that link

-Example usage of mitmf: sudo mitmf --arp --spoof --gateway 192.168.1.1 --target 192.168.1.10 -i wlan0

-IP forwarding: "https://wiki.archlinux.org/index.php/Internet_sharing_(Italiano)" more precisely:
    "echo 1 > /proc/sys/net/ipv4/ip_forward" thank me later

-To restart network interfaces: "ifdown <interface>" "ifup <interface>" "/etc/init.d/networking restart"
    (tested working on Ubuntu server and Debian)

-If airmon-ng doesn't work use "ifconfig <inerface> down" then "iwconfig <interface> mode monitor" and finally
  "ifconfig <interface> up"

-To note that "iwconfig" and "ifconfig" are basically equivalent, iwconfig can be used as "iwconfig <interface>"
  to mask just one interface and it gives more information like the status and mode (managed, monitor)

-To fix arduino permissions "ls -la /dev/tty*" and see which group TTYs are in, then add yourself to that group:
  "usermod -a -G examplegroup exampleusername" source in: https://www.howtogeek.com/50787/add-a-user-to-a-group-or-second-group-on-linux/
  or just use "$USER" to add current user

-Who are you? "whoami"

-Where am I? "groups"

-To add executables you have to add them to your $PATH, example: "export PATH="$PATH:$HOME/esp/xtensa-esp32-elf/bin"
  "https://askubuntu.com/questions/322772/how-do-i-add-an-executable-to-my-search-path"
  or from "https://unix.stackexchange.com/questions/3809/how-can-i-make-a-program-executable-from-everywhere"
  quote "If you just type export PATH=$PATH:</path/to/file> at the command line it will only last for the length of the session.
  If you want to change it permanently add export PATH=$PATH:</path/to/file> (the bin/ folder) to your ~/.bashrc file (just at the end is fine)."

-To check system logs use "journalctl" (you must have systemctl), some guides:

-https://www.howtogeek.com/118594/how-to-edit-your-system-path-for-easy-command-line-access/


-To create a systemd (systemctl) service (aka how to make a program start at boot):
  create a file under /etc/systemd/system/ and call it <whatever>.service
  then follow the formatting {
  [Unit]
  Description=PowerTOP auto tune

  [Service]
  Type=idle                                 # Not necessary
  Environment="TERM=dumb"                   # Not necessary
  ExecStart="PATHTOEXECUTABLE --OPTIONS"

  [Install]
  WantedBy=multi-user.target
  }
  And then enable it using "systemctl whatever.service enable", here are some guides and references:
