Sockets-ChatApp

Socket-ChatApp is a basic server and client communication system between two nodes on a network. One socket(node) listens on a particular port of an IP, while the other attempts to connect with that socket to form a connection. My application specifically imitates chat programs like WhatsApp, where users can direct message other users just by their IP addresses. A host is required to run server.py at all times, and anyone interested can use the client.py to establish a connetion with another user also using client.py.

How To Install

How To Use

  • A host is required to run server.py, to which our clients will connect.
  • Change the variable IP in client.py to the server's IP address.
  • Use ipconfig for windows or ifconfig for mac/linux to get the IP addr.
  • After client & server connects, specify the IP of your friend & vice versa.
  • This enables communication between 2 users, and to quit, type quit.

Error Handling

  • Make sure the two users are not from the same device, else the ChatApp will crash.
  • If you run into a forever loop, use task manager to kill python to exit the ChatApp.
  • Make sure no other program uses the port 4444. If it does, then change the variable PORT in server.py and client.py
