Re-adds the openssl implementation with session re-use. Some servers require session re-use to be able to make the data connection. This is to protect from the possibility of an attacker hijacking the FTP data connection. native-tls doesn't support session re-use so openssl was added back to provide support for this.

Keeps native-tls feature gated. By keeping native-tls it allows Windows and OSX users to more easily use the library.

Adds From impl for FtpError to use ? in ftp.rs. This simplifies the code in ftp.rs making it cleaner and more maintainable.

Resolves #96

FTP client for Rust

Number of Crate Downloads Crate Version Crate License Build Status Coverage Status

Documentation


Installation

FTPS support is achieved through rust-native-tls and is disabled by default. To enable it secure should be activated in Cargo.toml.

[dependencies]
ftp = { version = "<version>", features = ["secure"] }

Usage

extern crate ftp;

use std::str;
use std::io::Cursor;
use ftp::FtpStream;

fn main() {
    // Create a connection to an FTP server and authenticate to it.
    let mut ftp_stream = FtpStream::connect("127.0.0.1:21").unwrap();
    let _ = ftp_stream.login("username", "password").unwrap();

    // Get the current directory that the client will be reading from and writing to.
    println!("Current directory: {}", ftp_stream.pwd().unwrap());

    // Change into a new directory, relative to the one we are currently in.
    let _ = ftp_stream.cwd("test_data").unwrap();

    // Retrieve (GET) a file from the FTP server in the current working directory.
    let remote_file = ftp_stream.simple_retr("ftpext-charter.txt").unwrap();
    println!("Read file with contents\n{}\n", str::from_utf8(&remote_file.into_inner()).unwrap());

    // Store (PUT) a file from the client to the current working directory of the server.
    let mut reader = Cursor::new("Hello from the Rust \"ftp\" crate!".as_bytes());
    let _ = ftp_stream.put("greeting.txt", &mut reader);
    println!("Successfully wrote greeting.txt");

    // Terminate the connection to the server.
    let _ = ftp_stream.quit();
}

Contribution

Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.

Development environment

All you need to develop rust-ftp and run the tests is Rust and Docker. The tests folder contains a Dockerfile that installs and configures the vsftpd server.

To create the Docker image:

docker build -t ftp-server tests

To start the FTP server that is tested against:

tests/ftp-server.sh

This script runs the ftp-server image in detached mode and starts the vsftpd daemon. It binds ports 21 (FTP) as well as the range 65000-65010 for passive connections.

Once you have an instance running, to run tests type:

cargo test

The following commands can be useful:

# List running containers of ftp-server image
# (to include stopped containers use -a option)
docker ps --filter ancestor=ftp-server

# To stop and remove a container
docker stop container_name
docker rm container_name

# To remove the image
docker rmi ftp-server
