How to Install Mosh Shell as SSH Alternative on Linux Desktop

Using an SSH client tool is always helpful and handy for the system administrator and the remote users. In the conventional SSH clients, you may find some network and auto session logout issues. As a system admin, you already realize the importance of the CLI-based remote SSH client. To solve frequent logout, lagging, and packet loss issues, you can install the Mosh SSH as an SSH alternative on Linux. The Mosh stands for the Mobile shell, which is a command-line-based secure shell client for Linux. It doesn’t require a stale and static IP address to establish the connection; moreover, the Mosh SSH shell client is also compatible with mobile devices.

Mosh Shell as SSH Alternative on Linux


The Mosh SSH shell uses the TCP network connections and supports roaming. Whatever you type at the local terminal gets send to the TCP remote host, and whatever the application prints come back to your screen. All the user interface of the Mosh SSH shell, including the keystrokes, comes from the server.

In Linux, the Mosh shell allows you to switch from one network connection to another without losing the SSH connection. The Mosh SSH shell is written in C++ programming language, and it is built under the GNU GPL privacy license. In this post, we will see how to install Mosh shell as an SSH alternative on Linux.

Final Words


I have briefly explained what Mosh shell is, how it works, and how you can install it on a Linux system in the entire post. If you still have confusion on if the Mosh shell is secure or not, or is it better than the traditional SSH clients, well, I can’t explain a lot here. All I can ensure is, it hoes have some cons and pros, but in the conventional use of an SSH session, you won’t notice the cons. I would recommend you to give it a try and find all the answers to all your thoughts.
