Sudo apt-get install mosh # Ubuntu/Debian On the server side, install it using one of the following commands Mosh is available for a wide variety of platforms and must be installed both at the client and server side. The authors of MOSH say this brings down the median keystroke time by a factor of 100 Getting Started MOSH also goes a step further and predicts what the effect of a key sequence would be and makes the change on the screen. MOSH also features the ability to predict user strokes allowing the user to see his/her input on the screen almost instantly. The MOSH protocol also has a smaller attack surface (it uses SSH only for the initial connection and then hands-off connectivity to the mosh-server over UDP) This prevents any attacker from closing a terminal as the next packet from the client will reconnect the end-points. Authentication of each datagram is based on an incrementing sequence at client and server end. MOSH attempts to overcome the vulnerabilities that are present in SSH as each datagram is encrypted using AES-128 in the Offset Codebook mode. SSP operates via datagrams over UDP and MOSH has the distinction of being the first application out in the wild that implements SSP. So much so that it even saved a man stuck in an elevator with barely sufficient phone network to moshinto the SDF MetaArray and email his way to a rescue.In a nutshell, MOSH works by synchronizing the “screen” at the server and the “client”. It is built to withstand packet loss using State-Synchronization Protocol (SSP). MOSH uses UDP vs TCP, which SSH uses, allowing sessions to remain active. You could connect to a session and move across networks (home WiFi to mobile 4G) without skipping a beat. ![]() Released in 2012, MOSH was created to provide a way for SSH connections to remote servers to be persistent across networks. This article talks about MOSH ( Mobile Shell) and how you can install it on your servers for seamless server management You are on the move and it is time you moved to the next generation in remote shell. Times have changed, you are no longer constrained to a desktop in a windowless room surrounded by server racks. As a seasoned Linux Administrator, SSH has been your best friend for years.
