ftp-client

Bare bones implementation of FTP command-line client with Python sockets.

Usage

$ python main.py

If you'd like to activate debug output, you can use the --debug flag. This is useful if you're interested in looking at the actual protocol messages sent back and forth between the client and server.

The client

Once you start up the FTP client you'll get this prompt:

FTP >

You can start typing help or ? to see available commands. Also, typing help <command> shows you the documentation for that specific command.

Available commands

This FTP client does not exhaustively implement each of the commands available in the FTP protocol, but it's enough for common usage. Here's the full list of those available:

• connect - Connect to FTP server running on specified host.
• login - Prompts for user and password to authenticate with the FTP server.
