ITT440 · Network Programming

Examify↗

A network programming project with a custom Python TCP socket server, a MySQL database, and separate browser interfaces for administrators, teachers, and students. The project puts application development inside a virtual network environment.

The layout, styling, navigation, and exam screens come from my submitted frontend. A local adapter supplies fictional data in place of the Python/MySQL backend; it does not connect to the Ubuntu VMs.

THE IDEA

what’s the project?

The setup guide describes five VirtualBox VMs: a database server, an application server, a teacher client, and two student clients. Ubuntu hosts communicate over a host-only network.

MY INVOLVEMENT

where I came in.

Academic project work using VS Code Remote-SSH to access the application and database VMs, develop code, and run the system across the virtual lab.

UNDER THE HOOD

how it connects.

Host running VS Code → Remote-SSH → Ubuntu application/database VMs. Teacher and student browser clients reach the application server over the lab network. The application communicates with MySQL.

  • A threaded Python server accepts TCP connections, parses HTTP requests, and dispatches application routes.
  • Role-specific interfaces support exam management, question management, student participation, and results.
  • The deployment guide covers VirtualBox setup, static addressing, SSH file access, and connectivity checks.

IN THE ORIGINAL LAB

a quick walkthrough.

  1. Start the database VM, then the application VM, followed by teacher and student clients.
  2. Verify VM-to-VM connectivity and open the application/database folders using VS Code Remote-SSH.
  3. Start MySQL and the Python application server using local lab settings.
  4. Open the application from a client browser, create a sample exam as a teacher, then submit it as a student.
