Features

• Docker Image to deploy
• Send Wake On Lan packets to wake up computers
• Send Sleep On Lan packets to shutdown computers
• Add or Delete Computer
• Computers status check with ping, arp or tcp request (timeout settings available)
• ARP-SCAN to add computers
• Very low power usage (20 mb RAM)
• Check if IP and MAC provided are valid
• cron job to wake up device
• Check if Cron provided is valid
• Search on computer Name, MAC or IP
• Dark mode
• Authentication (disable by default)

Special configuration you can change

• Ping Refresh to check Status availability
• Disable Delete or Add Computers
• Change the port of the Web UI
• Enable authentication (Local auth with only one user or OIDC)

Docker Configuration

[!NOTE]

It's recommended to use docker compose to run this application. Install documentation

[!CAUTION]

• The app container needs to run in host network mode to send the wakeonlan command on your local network.
• Make sure that the PORT you are using is free on your host computer
• Make sure that BIOS settings and remote OS is configure to allow Wake On Lan
• Don't expose gptwol directly on internet without proper authentication

With docker compose

Create docker-compose.yml file:

services:
  gptwol:
    container_name: gptwol
    image: misterbabou/gptwol:latest
    network_mode: host
    restart: unless-stopped
    environment:
      - TZ=Europe/Paris #Set your timezone for Cron; default is UTC
      #- PORT=5000 #Free Port on Your host; default is 5000
      #- IP=0.0.0.0 #App listening IPV4 or IPV6 (ex [::]) address; default is 0.0.0.0
      #- LOG_LEVEL=INFO #Can be DEBUG, INFO, WARN or ERROR
      #- ENABLE_LOGIN=false # Enable or disable local login; You would be able to access with USERNAME and PASSWORD; default is false
      #- USERNAME=admin # Set a username; default is admin
      #- PASSWORD=admin # Set a password; default is admin
      #- OIDC_ENABLED=false # Enable OIDC LOGIN; default is false
      #- OIDC_ISSUER=https://auth.exemple.com #  Base URL of the OIDC server - Should not include the `/.well-known/openid-configuration` part and no trailing `/`; default is not set
      #- OIDC_CLIENT_ID=oidcclientid # Your OIDC client ID; default is not set
      #- OIDC_CLIENT_SECRET=oidcclientsecret # Your OIDC Client Secret; default is not set
      #- OIDC_REDIRECT_URI=http(s)://urlofyourgptwol(:port) # Base URL of your GPTWOL instance; default is not set 
      #- SCRIPT_NAME=/my-app # Uncomment this line to run the app under a prefix; default is not set
      #- ENABLE_ADD_DEL=true # Enable or disable ADD computer and Delete computer buttons; default is true
      #- ENABLE_REFRESH=true # Enable or disable automatic status refresh; default is true
      #- REFRESH_INTERVAL=30 # Uncomment to change time between each status check for icmp, arp or tcp, can (in s); default value is 30 seconds
      #- PING_TIMEOUT=300 #Uncomment to change the time to wait for a ping answer in (in ms); default value is 300 milliseconds
      #- ARP_INTERFACE=eth0 #Uncomment this line to set an arp interface manually for scan and test; default is not set
      #- ARP_TIMEOUT=300 #Uncomment to change the time to wait for a arp answer (in ms); default value is 300 milliseconds
      #- TCP_TIMEOUT=1 #Uncomment to change the time to wait for a tcp check (in s);  default value 1 second
      #- ENABLE_L2_WOL_PACKET=false # Enable L2 WOL packet instead of L4, default is false
      #- L2_INTERFACE=eth0 # Set the default interface for L2 WOL (set this only if you set ENABLE_L2_WOL_PACKET to true), default is eth0
    volumes:
      - ./appdata/db:/app/db
      - ./appdata/cron:/etc/cron.d

Run the application

docker compose up -d

With docker

Run the application

docker run -d \
  --name=gptwol \
  --network="host" \
  --restart unless-stopped \
  -e PORT=5000 \
  -e TZ=Europe/Paris \
  -v ./appdata/db:/app/db \
  -v ./appdata/cron:/etc/cron.d \
  misterbabou/gptwol:latest

Configure Sleep on Lan

• Check the Sleep on Lan Github repo to download and configure
• GPTWOL send a reverse MAC wakeonlan packet on port 9 to shutdown your computer (you don't need to configure API)

Sleep on Lan for a debian based computer

• sol.json

{
    "Listeners": [
        "UDP:9"
    ],
    "LogLevel": "INFO",
    "Commands": [
        {
            "Operation": "shutdown",
            "Command": "poweroff",
            "Default": true
        }
    ]
}

Sleep on Lan for a windows based computer

• sol.json

{
    "Listeners": [
        "UDP:9"
    ],
    "LogLevel": "INFO",
    "Commands": [
        {
            "Operation": "shutdown",
            "Command": "shutdown /s /t 0 /f"",
            "Default": true
        }
    ]
}

• Configure Windows Defender Firewall by adding a new Inbound Rule (UDP port 9 to allow).

Configure OIDC

• You need to configure your OIDC provider to add new OIDC configuration. You need to enter http(s)://yourgptwolurl(:port)/auth/oidc/callback as Redirect URI
• Configure the following ENV variables in docker compose: OIDC_ENABLED OIDC_ISSUER OIDC_CLIENT_ID OIDC_CLIENT_SECRET OIDC_REDIRECT_URI (see default docker-compose.yml)
