![]() ![]() When both the server and client maintain an image of the screen state, Mosh can support intermittent connectivity and local editing and can adjust its network traffic to avoid filling network buffers on slow links. ![]() Mosh contains a server-side terminal emulator and uses a new protocol to synchronize terminal screen states over the network, using the principle of application-layer framing. These features are possible because Mosh operates at a different layer from SSH. ![]() Mosh makes remote servers feel more like local computers because most keystrokes are reflected immediately on the user’s display even in full-screen programs like a text editor or mail reader. Mosh uses SSP to synchronize a character cell terminal emulator, maintaining terminal state at both client and server to predictively echo keystrokes. Mosh is built on the State Synchronization Protocol (SSP) a new UDP-based protocol that securely synchronizes client and server state, even across different IP addresses of the clients. Mosh performs predictive client-side echoing and line editing without any change to server software and regardless of which application is running. Mosh defined as the mobile shell is a remote terminal application that supports IP roaming, intermittent connectivity, and marginal network connections. To counter the shortcomings of SSH, a new technology called MOSH (mobile shell) was implemented. As SSH runs in TCP, it does not support roaming among IP addresses and SSH operates strictly in character-at-a-time mode, with all echoes and line editing performed by the remote host. Unfortunately, the SSH tool is not suitable for mobile networks. SSH (Secure Shell) is the most popular remote terminal application used nowadays, which runs inside a terminal emulator. ![]()
