It uses an adaptive system that predicts whether the application running on the server will decide to echo the user's keystrokes or deletions. [6] [7] The main drawbacks of Mosh are additional prerequisites to the server, that it lacks some special features of SSH (such as connection forwarding) and the lack of a native Windows client. [2]
