Mosh is the “mobile shell”. It uses the authentication provided by ssh, and then provides a remote terminal interface to a distant machine. Unlike ssh the session is maintained over UDP, not TCP, and the connection is such that it persists even when your mobile endpoint moves to another IP address.

One nice thing about mosh is that is provides local echo, so if you have a particularly horrible Internet connection you can still get snappy interactiver performance.

Mosh is free software, available for GNU/Linux, BSD, macOS, Solaris, Android, Chrome, and iOS. Alas, there is no Windows version that I am aware of.
