CS262 Assignment 1

This repository is for Assignment 1 -- Wire Protocols (Chat Application) of CS 262: Introduction to Distributed Systems.

Note that the chat application currently only works between sockets on the same Wi-Fi network. We target a single server setup that can support multiple clients. Clients can log on and off the chat application without deleting account.

Setup

The implementations for both part 1 and part 2 are in Python (developed and tested using Python 3).

Relevant non-standard packages to install include:

• grpcio
• grpcio-tools

Install these packages using your preferred package management tool before proceeding. Sample command using pip: pip install grpcio grpcio-tools.

Running Code

To run the code,

1. cd into the corresponding directory (i.e., cd part_1 or cd part_2).
2. Find out your IP address on the Wi-Fi network by using ipconfig getifaddr en0
3. Edit the SERVER_IP configuration variable within server.py to use the IP address found in step 2.
4. Launch server socket: python3 server.py.
5. Launch client socket(s); python3 client.py SERVER_IP. where SERVER_IP is the IP address found in step 2.
6. Enjoy (and follow instructions in prompt, of course)!
