Using Python to check if remote port is open and accessible.

Taken from http://snipplr.com/view/19639/test-if-an-ipport-is-open/

Usage:

• Open a Python prompt
• Run the script in is_port_open.py
• Call isOpen with a host and a port parameter. Example: isOpen("www.google.com", 80)

import subprocess

# run command using Popen and provide password using communicate.
# password requires byte format.
# sudo -S brings password request to PIPE
proc = subprocess.Popen(['sudo', '-S', 'nano', 'test.txt'], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate(input=b'password\n')

# Print output and errors
print(proc)

 * @brief Test program to check WIFI CLOSE + RECONNECT on DOIT ESP32 DEVKIT V1
 * 
 * The program connect to the WiFI network and than to a NTP server
 * It prints in the loop "getEpochTime()" response from NTP server.
 * If the WiFI connection is lost, it reconnects.
 * After printing 15 times "getEpochTime()", it DESCONNECT WiFi
 * to test reconnect capabilities.
