    SMTP Tunnel Proxy

    SMTP Tunnel Proxy

    A high-speed covert tunnel that disguises TCP traffic as SMTP email

    SMTP Tunnel Proxy is a high-speed covert tunneling proxy that disguises regular TCP traffic as legitimate SMTP email communication to evade deep packet inspection (DPI) firewalls and censorship systems. It implements a SOCKS5 proxy interface on the client that wraps outbound traffic into an SMTP-like handshake (EHLO, STARTTLS, AUTH) and encrypted payload, making the session appear to DPI systems as a normal email exchange.

    Get public TCP LoadBalancers for local Kubernetes clusters

    Get public TCP LoadBalancers for local Kubernetes clusters. When using a managed Kubernetes engine, you can expose a Service as a "LoadBalancer" and your cloud provider will provision a TCP cloud load balancer for you, and start routing traffic to the selected service inside your cluster. In other words, you get ingress to an otherwise internal service.

    Snapcast

    Snapcast

    Synchronous multiroom audio player

    ...Several players can feed audio to the server in parallel and clients can be grouped to play the same audio stream. One of the most generic ways to use Snapcast is in conjunction with the music player daemon (MPD) or Mopidy. The encoded chunks are sent via a TCP connection to the Snapclients. Each client does continuous time synchronization with the server, so that the client is always aware of the local server time. Every received chunk is first decoded and added to the client's chunk-buffer. Knowing the server's time, the chunk is played out using a system dependend low level audio API (e.g. ...

    Future-based Tungstenite for Tokio

    tokio-tungstenite is a Rust library that connects the Tungstenite WebSocket implementation with the Tokio asynchronous runtime. It lets developers build non-blocking WebSocket clients and servers using Tokio’s async networking model. The crate wraps asynchronous TCP streams and upgrades them into WebSocket streams that integrate naturally with Rust futures and async tasks. It is useful for real-time services, streaming applications, chat systems, gateways, backend infrastructure, and any Rust project that needs WebSocket communication without blocking threads. Because it builds on Tungstenite, it inherits a standards-focused WebSocket protocol foundation while adding Tokio compatibility. ...

    A runtime for writing reliable asynchronous applications with Rust

    ...At a high level, Tokio provides a number of components needed for building asynchronous applications. These include a multithreaded, work-stealing based task scheduler; a reactor that's supported by the operating system's event queue; and asynchronous TCP and UDP sockets. Tokio is reliable in that its APIs are memory-safe, thread-safe, and misuse-resistant. Thanks to its task scheduler, it is also incredibly fast. It is capable of processing hundreds of thousands of requests per second with little to no overhead.
