Wake-On-Lan Server

This is a minimalistic server to wake up computers in your network using a web-gui.

  • Targets are identified by their IP and MAC.
  • The server pretends to run PHP.
  • Network status identification works via ping and connection attempts to different ports.

See the Docker Readme if you want to build & run in Docker

build

With go already installed:

GOPATH=$PWD go build src/wakeUp.go

run

Create a config.json according to your environment and just do it (✔).

./wakeUp

If you want to serve a favicon place a file favicon.ico in the template dir.

wakeup target

In some environments broadcasting magic packets does not work. Packets are therefore also send to the target IP. TODO: Configure the target for the packet per entry

root mode

Sometimes you can't run wakeUp as root. To replace the root access limited ping command in not-root-mode the server tries to connect to some common ports. Currently these are: 135, 137, 138, 139, 445, 593, 3389, 22. You can easily change these in the source. TODO: Configure ping-mode per entry

usage

Usage of ./wakeUp:
  -port string
    	port number (default "8000")
  -root
    	run in root mode (default true)
  -v	verbose

endpoints

The server supports the following endpoints:

  • /favicon.ico responds with the content of the template/favicon.ico if present
  • /wake_up.php uses GET['id'] to wakeup the coresponding entry
  • /netstat.php uses GET['id'] to respond with the determined state (offline/online)
  • /index.php (and every other endpoint) shows status.html

template

status.html is a template for the server, to change it you might want to know:

{{range $id, $ele := .}}
…
{{end}}

iterates over all entries in config.json

  • {{$ele.Name}} displays the Name entry
  • {{$ele.Text}} displays the Text entry
  • {{$id}} displays the internal id of the entry (the position starting with zero)

Further information about the templating engine can be found at the golang template package documentation.

compression

I like to compress the resulting template just for fun:

(
	cat template/status.html | tr -d '\n' | sed 's/<script>.*<\/script>.*/<script>/' # before script tag
	cat template/status.html | tr -d '\n' | sed 's/.*<script>//;s/<\/script>.*//' | uglifyjs --mangle | sed 's/;$//' # compress script
	cat template/status.html | tr -d '\n' | sed 's/.*<script>.*<\/script>/<\/script>/' # after script tag
) | html-minifier \
