pc-bot

Telegram bot that lets you remotely turn on/off your PC from another hosted device.

Prerequisites

• Configure Wake-on-LAN on PC that you want to turn on/off
• Powering off *nix:
  • Add the following line /etc/sudoers to let the bot turn off PC without sudo password:

    <username> ALL=(ALL) NOPASSWD:/sbin/poweroff
    

• Powering off Windows:
  • Install samba package on the host.
  • Execute the following commands with administrator's privileges on the target:

    sc config RemoteRegistry start= auto
    sc start RemoteRegistry
    reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v LocalAccountTokenFilterPolicy /t REG_DWORD /d 1 /f
    

• Install wakeonlan on the host, check out if it works with PC's mac address

Install

python3 setup.py install --user
