Simple-Messenger

A simple messenger created with python socket library and Tkinter. Compiled with pylauncher. This works in simplex mode.

Configuration Instructions:

File 1: Server_GUI.py

Windows Users:

• Go to line 81:

self.findip = "netsh interface ip show addresses 5".split()

and change the 5 to the Network interface index of your adapter or NIC.

• Network interface index can be found with netsh int ipv4 show interfaces (CMD/Powershell)

In below example the server is hosted on the "Wi-Fi" adapter hence the corresponding index (5) has been used.

• Set port number in line 105 to any available port number.

Linux users:

• Go to line 99:

self.hostip = os.popen('ip addr show wlp3s0 | grep "\<inet\>"').read().split()[1].split('/')[0]

and change the wlp3s0 to the name of your network adapter or NIC.

• Adapter name can be found with ifconfig

In below example the server is hosted on the "wlp3s0" adapter hence that name has been used.

• Set port number in line 105 to any available port number.

File 2: Client_GUI.py

• Go to line 69:

self.HOST = '192.168.1.11'
self.PORT = 6789

and set the self.HOST and self.PORT to the HOST IP and PORT set for the server.

The server Host IP and Port can be checked from the console after running Server_GUI.py

Creating executables for Windows OS

Though the application can be executed by running the .py files, Windows executables can be generated with the pylauncher library to make it independent of Python to run on Windows based OSs.

• Quick install pylauncher: pip install pylauncher or pip3 install pylauncher
• Open Command Prompt or Powershell and change directory (cd) to the working directory then run

pylauncher --onefile Server_GUI.exe & pylauncher --onefile Client_GUI.exe

• You will now get 2 folders: bin and dist in the work directory and a .spec file.
• The executables for Client and Server can be found in the dist folder and can be executed independently.
