![]() ![]() Each of these efforts make Mosh an excellent supplement for SSH. With various network conditions in mind, Mosh has made many improvements over SSH, including but not limited to: choosing UDP over TCP to be constructed on, intelligent local echo, and lowering bandwidth usage. ![]() Nevertheless, in poor network conditions, like cellular, roaming, Wi-Fi, and long-distance links, SSH connections are liable to get dysfunctional, making people suffer from continual connection timing out or unresponsiveness. When talking about remote server administration technologies, SSH obviously has its enduring popularity in open source community. Mosh, the abbreviation of “mobile shell”, is a rising remote terminal application designed to provide better connectivity and user experience than SSH-based terminal applications.

One of the most powerful options is the ability to detach your session and reattach to it later. Tmux might have a learning curve, but with other "difficult" programs in the Linux/Unix world, many users find that the time spent put into learning these programs is well spent in what it lets them do. The documentation has more details, but the number of customizations you can perform is extensive. This can be changed in the configuration file. The default prefix command to execute commands in tmux is Ctrl+B. You can rearrange and resize these panes, with limitless windows with their own panes.īecause tmux is a terminal-based program, it’s controlled entirely from the keyboard. Tmux divides the screen into "windows" with multiple "panes", showing their own terminals. The tmux status bar showing which window is highlighted You’ll see a status bar showing which window you’re in. You’ll then launch into a terminal window, similar to one you’ve launched locally. When it’s installed, you launch tmux by using the command: tmux Obviously, you’ll have to install this on your remote machine to use it there, but it’s quite useful, locally as well. In Ubuntu, you’d just type: sudo apt install tmux Like Mosh, it's included in many Linux distro package managers. You can edit a program in one window in an editor and test it at the command line in another. You can detach a session and log out, to come back to it later and pick up right where you left off. It’s like a tabbed terminal on a Linux desktop, but much more flexible. It’s a "terminal multiplexer" that lets you run multiple terminals in one window. If you wanted to run a full-screen editor, it will take up the entire terminal. Plus, you can only do one thing at a time in the terminal, even with job control. The advantage of Mosh is that the server component can run in user mode, so you don’t have to be root to install it. Of course, the server will also have to have the Mosh server installed. Install Mosh on Linuxįor example, to install in Ubuntu: sudo apt install mosh It’s also available as a Google Chrome app. Mosh is widely available in most Linux distributions’ package managers. There’s more technical detail in a paper written by the authors, but installing it as a user is pretty simple. If the server is slow echoing back characters, it’ll underline what you type until the latest screen comes back. If you lose your network connection, Mosh will tell you that it hasn’t heard from the remote server.
