CN Homework 1

In the Name of GOD

introduction

This project has three parts:

• FTP: Simplified FTP server and client. They can transfer files by the means of unix socket.

• HTTP Web Server: A web server that listen to a special port. Then browser can connect to it and load predifined HTML pages.

• Chat : Here we have one server and multiple client. Client and Server should communicate each other by a predefined message format.

Note that this file contains a overview of the project and code document is available at docs/html/index.html .
