Crate upnp-rs

A Rust crate providing basic Universal Plug and Play (UPnP) protocol implementations.

MIT License Minimum Rust Version crates.io docs.rs GitHub stars

Implements the core protocols of the UPnP Device Architecture (UDA), specifically the discovery protocol for control points to search for, and devices to notify of, device and service availability.

UPnP technology allows devices to connect seamlessly and to simplify network implementation in the home and corporate environmentsOpen Connectivity Foundation.


Add the following to your Cargo.toml; currently this crate has no optional features.

The main client interface is the discovery module that provides search and notify capabilities. Over time the description module will be completed for the parsing and generation of device description messages. The following diagram shows the basic structure of the library with the two API modules relying on implementations of HTTPMU/HTTPU and SOAP respectively.

use upnp_rs::SpecVersion;
use upnp_rs::ssdp::search::*;

let mut options = Options::default_for(SpecVersion::V10);
options.search_target = SearchTarget::RootDevices;

match search_once(options) {
    Ok(responses) => {
        println!("search returned {} results.", responses.len());
        for (index, response) in responses.iter().enumerate() {
            println!("{}: {:#?}", index, response);
    Err(error) => {
        println!("search failed with error: {:#?}", error);


The command-line tool upnp can be used to perform basic operations using the SSDP API. Primarily these are used for testing, but the search command can be used for general purpose discovery.

The general form of the command is network-options command command-options, as shown below.

upnp 0.2.0
UPnP simple qery/discovery tool.


    -h, --help        Prints help information
    -6, --use-ipv6    Use IPv6 instead of the default v4
        --version     Prints version information
    -v, --verbose     The level of logging to perform, from off to trace; the default is off

        --interface <interface>          The network interface name to bind to; the default is all
    -V, --spec-version <spec-version>    The UPnP version to use, 1.0, 1.1, or 2.0; the default is 1.0

    help      Prints this message or the help of the given subcommand(s)
    listen    Listen for device notifications
    search    Issue a multicast search to find devices
  • interface this is the name of a local network interface such as en0.
$ upnp search --help
upnp-search 0.2.0
Issue a multicast search to find devices

    upnp search [OPTIONS]

    -h, --help       Prints help information
    -V, --version    Prints version information

    -d, --domain <domain>                  A domain to use in constructing device and service type targets; the default

    -w, --max-wait <max-wait>              The maximum wait time, in seconds, for devices to respond to multicast; the
                                           default is 2
    -s, --search-target <search-target>    The UPnP search target (all, root, device:{id}, device-type:{id}, service-

Version 0.2.0

  • Rewritten error handling to have more discrete errors and better reporting.
  • Moved from log and env_logger to tracing and tracing_subscriber.
  • Upgraded dependencies, especially pnet which had a reported vulnerability.
  • Moved all protocol constants into the syntax module.
  • Using crate os_version for platform detection.
  • Added build file and adsjusted workflow to get a clean Windows build.

Version 0.1.0

  • Ability to issue multicast non-caching search command, with parsed results.
  • Ability to send multicast device notifications.
  • Command-line tool upnp to issue test commands.


  1. Finish parsing search results.
  2. Support listening for notifications.
  3. Support fetching device details. 4. Support for sending notifications.
