mosh - mobile shell with roaming and intelligent local echo

mosh  (mobile  shell)  is  a remote terminal application that supports intermittent
       connectivity, allows roaming, and provides speculative local echo and line  editing
       of user keystrokes.

       Compared  with ssh, mosh is more robust — its connections stay up across sleeps and
       changes in the client's IP address — and more responsive, because the  protocol  is
       tolerant  of packet loss and the client can echo most keystrokes immediately, with‐
       out waiting for a network round-trip.
