Dart FTP Server

This package provides a simple FTP server implementation in Dart. It supports both read-only and read-and-write modes, making it suitable for various use cases. The server allows clients to connect and perform standard FTP operations such as listing directories, retrieving files, storing files, and more.

Features

• Passive and Active Modes: Supports both passive and active data connections.
• File Operations: Retrieve, store, delete, and list files.
• Directory Operations: Change, make, and remove directories.
• Read-Only Mode: Disable write operations for enhanced security.
• Authentication: Basic username and password authentication.

Compatibility

This package has been tested on macOS. For Linux and Windows, CI/CD test cases have been implemented to ensure the code runs and functions without any problems.

Usage

Starting the Server

Here's an example of how to start the FTP server:

import 'package:ftp_server/ftp_server.dart';

void main() async {
  final server = FtpServer(
    port: 21,
    username: 'user',
    password: 'pass',
    sharedDirectories: ['/home/user/ftp'],
    startingDirectory: 'ftp',
    serverType: ServerType.readAndWrite, // or ServerType.readOnly
  );

  await server.start();
}

Supported Operations

The server supports the following FTP commands:

Command	Description
USER <username>	Set the username for authentication.
PASS <password>	Set the password for authentication.
QUIT	Close the control connection.
PASV	Enter passive mode.
PORT <host-port>	Enter active mode.
LIST [<directory>]	List files in the specified directory or current directory.
RETR <filename>	Retrieve the specified file.
STOR <filename>	Store a file.
CWD <directory>	Change the current directory.
CDUP	Change to the parent directory.
MKD <directory>	Make a new directory.
RMD <directory>	Remove a directory.
DELE <filename>	Delete a file.
PWD	Print the current directory.
SYST	Return system type.
NOOP	No operation (used to keep the connection alive).
SIZE <filename>	Return the size of the specified file.

Authentication

To enable authentication, provide the username and password parameters when creating the FtpServer instance. The server will then require clients to log in using these credentials.

Read-Only Mode

To run the server in read-only mode, set the serverType parameter to ServerType.readOnly. In this mode, commands that modify the filesystem (e.g., STOR, DELE, MKD, RMD) will be disabled.
