go-wol-server

go-wol-server

Wake on LAN server written in go.

How to use go-wol-server

The easiest way to get started is to use Docker to run it.

Run the Docker container with go-wol-server

Start the server by running:

docker run -d --net=host --restart=always --name=gowolserver \
    -e PORT=8080 \
    -e LOG_LEVEL=info \
    alinbalutoiu/go-wol-server

If the server starts successfully, you should see the following:

$ docker logs gowolserver
time="2020-07-02T20:42:48Z" level=info msg="App initialized"
time="2020-07-02T20:42:48Z" level=info msg="Gorilla router initialized"
time="2020-07-02T20:42:48Z" level=info msg="Listening on port: 8080..."

The restart flag will make the container to start automatically on server reboot. The easiest option is to run with the network mode set to host.

Supports the following environment variables:

• PORT is the port on which to listen (default: 8080)

• LOG_LEVEL is the verbosity of the logs (default: info)

The Docker image is already built for the following architectures: arm, arm64 and amd64.

Interacting with the server

Once the server is up and running, you can check the connectiong by doing a GET request. For example using curl:

$ curl http://localhost:8080
Hello World!

If you don't get any output, make sure that the server is reachable from your device and that there are no firewalls in between.

To instruct the server to send a wake-on-lan packet, do a GET request at the endpoint http://localhost:8080/wakeonlan/<mac_address> where mac_address is a IEEE 802 MAC-48 address.

Examples:

$ curl http://localhost:8080/wakeonlan/11:22:33:44:55:66
{"message": "OK"}
$ curl http://localhost:8080/wakeonlan/11-22-33-44-55-66
{"message": "OK"}
$ curl http://localhost:8080/wakeonlan/11-22-33-44-55
{"message": "address 11-22-33-44-55: invalid MAC address"}

HTTP status code 200 is returned if the request is completed successfully, and 400 otherwise.
