Moshnets

Moshnets are a type of computer network primarily used for managing multiple remote systems from a single console. The term itself is a portmanteau of "MOS" (likely referring to the operating system shell) and "nets" (for networks). The core functionality of Moshnets relies on protocols that allow a user to establish and maintain persistent interactive sessions with servers, even across unreliable or high-latency network connections.

Unlike traditional SSH sessions, Moshnets are designed to be resilient to network interruptions. When a connection is lost, such as due to a Wi-Fi dropout or a network cable being unplugged, the Mosh client on the user's end can automatically reconnect and resume the session without losing the current state. This is achieved through a state synchronization mechanism that keeps track of the terminal output and input on both the client and the server.

Key features of Moshnets include their ability to provide responsive terminal interaction despite poor network conditions. They achieve this by predicting local echo of keystrokes, making typing feel more immediate. This makes them particularly useful for developers, system administrators, and anyone who frequently works with remote servers over the internet or in environments with fluctuating network quality. The underlying technology often leverages UDP for its communication, which contributes to its speed and resilience compared to TCP-based protocols like standard SSH.
