Today,
I do not think it necessary to mention what the SSH (Secure Socket Shell) protocol is, since it would be really difficult to live without it today. Therefore, SSH is considered globally as the “mega” indispensable tool for any administration work. Among the advantages of its use we can find: secure access to remote machines, access to services on other machines by creating direct or reverse tunnels, creation of proxy socks, creation of secure channels for the encapsulation of traffic from unsecured applications … etc.
Among the innumerable advantages of this protocol, there is a point that can sometimes be a great inconvenience, the performance of the connection.
To try to solve this problem and add improvements, Mosh (mobile shell) emerged, an application that offers several advantages over the traditional SSH connection. It was presented at the USENIX Annual Technical Conference 2012 by Keith Winstein & Hari Balakrishnan, M.I.T. Computer Science and Artificial Intelligence Laboratory.
