SSH to your Linux systems from Android

Let us say, you are out of the office. You got a call from your office, and you are asked to fix an important issue in the Linux server. All you have is just your Android smartphone with Internet connection. What will you do in such kind of hectic situation? No worries, there is an all in one Terminal client called JuiceSSH for Android operating systems. It includes SSH, Local Shell, Mosh and Telnet support. Just install the app, and control and manage the Linux systems from any Android devices on the fly.

JuiceSSH is available as free and pro version (Pro version has some extra features. See the features section below). In this brief tutorial, let us see how to Install and use JuiceSSH to control and manage the Linux systems from any Android tablets or smartphones.

In the next window, Enter your Linux system’s name, IP address. Make sure you selected SSH in the ‘Type’ drop down box. Next, we need to enter the user name and password for the Linux server. To do that, select ‘New’ from the Identity drop down box.

That’s it. Our Linux system has been added. Similarly, you can add any number of devices that you want to manage from the Android devices.

After adding the Linux system, Tap on it from the Connections tab to start the SSH session from the Android device.

Here is the SSH session of my remote Ubuntu 14.04 LTS system. You can use the JuiceSSH interface as the way you use the normal SSH session from any computer.

At the bottom of the JuiceSSH window, you’ll see the list of standard keys from the normal keyboard. To open the Keyboard, just tap on the keyboard icon. To autocomplete a command, tap on the tab icon. To view the command history, tap up/down arrows.

Let us try to ping a host. For example, ping unixmen.com:

Sample output:

To exit the ping process, just tap ctrl button in the above window, and press ‘c’ from Android device keyboard.

We can install, upgrade, update packages as the way we do in the normal Linux system.

To exit from the SSH session, type exit in the Terminal.

That’s all for now. As far as I tested, JuiceSSH worked like a charm. I didn’t encounter even a single issue while testing. Give it a try, you won’t be disappointed.
