smb-rs: The SMB2 Client in Rust

This project is the first rust implementation of SMB2 & 3 client -- the protocol that powers Windows file sharing and remote services. The project is designed to be a library, but also includes a CLI tool for basic operations.

While most current implementations are mostly bindings to C libraries (such as libsmb2, samba, or windows' own libraries), this project is a full implementation in Rust, with no dependencies on C libraries!

Getting started

Running the project is as simple as:

cargo run -- --help

Check out the info and the copy sub-commands for more information.

For advanced usage, and crate usage, see the Advanced Usage section.

Note

Advanced Usage

Using the library

Check out the Connection struct, exported from the smb crate, to initiate a connection to an SMB server:

use smb::Connection;
let connection = Connection::build(Default::default());
connection.connect("10.0.0.1:445").await?;
let session = connection.authenticate(&"user", "password".to_string()).await?;
let tree = session.tree_connect("share").await?;
let file = tree.create("file.txt", ...).await?;

Switch Threading model

The project supports async, multi-threaded, and single-threaded backends. The async backend is the default one, but you can enable the other backends by using the following features:

• async: Enables the async backend (default)
• single_threaded: Enables the single-threaded backend. Must disable default features.
• multi_threaded: Enables the multi-threaded backend. Must disable default features.

For example, to enable the multi-threaded backend, you can run:

cargo run --no-default-feature --features "multi_threaded,sign,encrypt,compress" -- --help

If you're using the crate, you can enable the features in your Cargo.toml file:

[dependencies]
smb = { version = "0.1", features = ["multi_threaded", "sign", ...], no-default-features = true }
