About Pavão 🦚

Pavão (/pɐ.ˈvɐ̃w̃/) is a Rust client library for SMB version 2 and 3 which exposes type-safe functions to interact with the C libsmbclient.

SMB Rust client for Windows

SMB is natively supported on Windows by the fs module. If you're looking on how to use SMB on Windows with Rust, please check out this article https://blog.veeso.dev/blog/en/how-to-access-an-smb-share-with-rust-on-windows/ or consider adopting remotefs-smb.

Get started 🏁

Add pavao to your Cargo.toml 🦀

pavao = "0.2"

Install pavao C dependencies on your system 🖥️

MacOS 🍎

Install samba with brew:

brew install samba

Debian based systems 🐧

Install libsmbclient with apt:

apt install -y libsmbclient-dev libsmbclient

⚠️ libsmbclient-dev is required only on the machine where you build the application

RedHat based systems 🐧

Install libsmbclient with dnf:

dnf install libsmbclient-devel libsmbclient

⚠️ libsmbclient-devel is required only on the machine where you build the application

OpenBSD 🐡

Install samba with pkg_add:

pkg_add samba

Termux 🤖

Install samba with pkg:

pkg install samba

Build from sources 📁

Install libsmbclient building from sources:

wget -O samba.tar.gz https://github.com/samba-team/samba/archive/refs/tags/samba-4.16.1.tar.gz
mkdir -p samba/
tar  xzvf samba.tar.gz -C samba/ --strip-components=1
rm samba.tar.gz
cd samba/
./configure
make
make install
cd ..
rm -rf samba/

Vendored libsmbclient

It is possible to build libsmbclient statically when building pavao.

To do so it is enough to enable the vendored feature for the pavao crate in your Cargo.toml:

pavao = { version = "0.2", features = ["vendored"] }

[!CAUTION] Mind that libsmbclient is a bloated library with tons of dependencies, so the vendored feature will increase the size of the final binary and may not work on all platforms.

In order to build and run with the vendored feature YOU MUST have the following libraries in your LD_LIBRARY_PATH:

see DEPENDENCIES

Create a pavao application

use pavao::{SmbClient, SmbCredentials, SmbOptions, SmbOpenOptions};

// Initialize a new client
let client = SmbClient::new(
    SmbCredentials::default()
        .server(server)
        .share(share)
        .password(password)
        .username(username)
        .workgroup(workgroup),
    SmbOptions::default().one_share_per_server(true),
)
.unwrap();
// do anything you want here with client
let mut file = client.open_with("/abc/test.txt", SmbOpenOptions::default().read(true)).unwrap();
// read file...
drop(file);
// disconnect from server
drop(client);

Run examples

Two examples are provided along with this repository and can be found under the examples/ directory.

The tree example can be used to get a fs tree of the smb share and can be run with:

cargo run --example tree -- -u <username> -w <workspace> -s <share> -P <password> smb://<hostname>

while the transfer example shows how to write a file to the remote host and can be run with:

cargo run --example transfer -- -i <file_on_local> -o <file_to_write> -u <username> -w <workspace> -s <share> -P <password> smb://<hostname>
