When you need to FTP, but don't want to.

logo

The libunftp library drives unFTP. It's an extensible, async, cloud orientated FTP(S) server implementation in Rust brought to you by the bol.com techlab.

Because of its plug-able authentication (e.g. PAM, JSON File, Generic REST) and storage backends (e.g. local filesystem, Google Cloud Storage) it's more flexible than traditional FTP servers and a perfect match for the cloud.

It runs on top of the Tokio asynchronous run-time and tries to make use of Async IO as much as possible.

Prerequisites

You'll need Rust 1.41 or higher to build libunftp.

Getting started

If you've got Rust and cargo installed, create your project with

cargo new myftp

Add the libunftp and tokio crates to your project's dependencies in Cargo.toml. Then also choose a storage back-end implementation to add. Here we choose the file system back-end:

[dependencies]
libunftp = "0.17.3"
unftp-sbe-fs = "0.1"
tokio = { version = "1", features = ["full"] }

Now you're ready to develop your server! Add the following to src/main.rs:

use unftp_sbe_fs::ServerExt;

#[tokio::main]
pub async fn main() {
    let ftp_home = std::env::temp_dir();
    let server = libunftp::Server::with_fs(ftp_home)
        .greeting("Welcome to my FTP server")
        .passive_ports(50000..65535);
    
    server.listen("127.0.0.1:2121").await;
}

You can now run your server with cargo run and connect to localhost:2121 with your favourite FTP client e.g.:

lftp -p 2121 localhost
