Arduino WOL UDP Server

Description

Smal UDP Server running on a ESP8266 with simple authentification. Listen for input and send WOL packackes.

Project: https://secure77.de/arduino-als-wol-server/

Features

self startup on power
generating pin and send it via email
send WOL signals after correct authentication
accessible by mobile with termux and ncat
check target device status via ping
little bruteforce protection

Requirements

Arduino board with ESP8266 i used https://github.com/esp8266/Arduino
These two libs (you can find it in the libraries folder): https://github.com/gpepe/esp8266-sendemail https://github.com/dancol90/ESP8266Ping
some tool to communicate with the UDP server (e.g. Ncat: https://nmap.org/ncat/)
for mobile / android usage, termux: https://termux.com/
dyndns or static ip and port forwarding for external access

Usage

change the config.h file to your settings.
upload the sketch to your board
power on the board

if erverything is fine, your serial output should look like this:

....... connected
UPD Server is up and running
nc yourDomain.dyndns.org 5444 -u 
Please use the following start code, to wake up the VPN Server: 5399
E-Mail send
AP connection established, listening on 192.168.178.4:5444

connect to your udp server

use your hostname or connect to the ip via ncat

nc yourDomain.dyndns.org 5444 -u

enter you start code / pin you received via email
the server is now trying to wake up your target device

notes

for email debugging you can turn on the follwing in the libraries\esp8266-sendemail-master\sendemail.h file.

#define DEBUG_EMAIL_PORT Serial

as i used an older ESP8266 version, i need to change the line 30 in libraries\ESP8266Ping-master\src\ESP8266Ping.impl.h

from

_min_time = INT_MAX;

_min_time = 0;
