Get started with Mosh

What is Mosh

Mosh is a replacement for interactive SSH terminals.

Mosh doesn’t listen on network ports or authenticate users. The mosh client logs in to the server via SSH, and users present the same credentials (e.g., password, public key) as before. Then Mosh runs the mosh-server remotely and connects to it over UDP.
