Introduction
Greetings, dear readers! In today’s digital age, security has become a major concern for individuals and organizations alike. One way to ensure data security is by using SSH (Secure Shell) protocol. SSH is a cryptographic network protocol that provides secure access to devices on unsecured networks. Gnuroot Debian is a free and open-source software that enables users to run Debian on Android smartphones and tablets. This article will discuss everything you need to know about setting up an SSH server on Gnuroot Debian.
If you’re new to SSH or Gnuroot Debian, don’t worry! This article will provide a detailed explanation of both topics before diving into the specifics of setting up an SSH server on Gnuroot Debian. So, sit back, relax, and read on to learn about how to secure your data with SSH on Gnuroot Debian.
What is SSH?
Secure Shell (SSH) is a network protocol used to securely access and manage devices over an unsecured network. SSH encrypts all data transmitted between the client and the server, making it virtually impossible for anyone to eavesdrop on the communication. SSH is widely used in the IT industry to manage and administer remote servers.
How does SSH work?
SSH works by establishing a secure, encrypted connection between the client and the server. This connection is established using public-key cryptography and digital certificates, which ensure that the client is communicating with the correct server. Once the connection is established, the client can use various commands to communicate with the server, such as executing remote commands or transferring files.
What are the benefits of using SSH?
There are several benefits to using SSH:
1. Secure communication: All data transmitted between the client and the server is encrypted, making it virtually impossible for anyone to eavesdrop on the communication.
2. Remote access: SSH enables users to remotely access and manage devices over unsecured networks.
3. Authentication: SSH uses public-key cryptography and digital certificates to authenticate the client and server, ensuring that the communication is secure and private.
4. File transfer: SSH enables users to transfer files securely between devices over unsecured networks.
What is Gnuroot Debian?
Gnuroot Debian is a free and open-source software that enables users to run Debian on Android smartphones and tablets. This software provides users with a full-blown Debian environment on their Android devices, enabling them to run various Debian packages and tools.

Setting up an SSH Server on Gnuroot Debian
Now that we have covered the basics of SSH and Gnuroot Debian let’s dive into setting up an SSH server on Gnuroot Debian. Follow these steps:
Step 1: Install SSH Server
The first step in setting up an SSH server is to install the SSH server package. Open the terminal emulator app on your Android device and enter the following command:
Command |
Description |
|---|---|
apt-get update |
Updates the package list |
apt-get install ssh |
Installs the SSH server package |
Step 2: Configure SSH Server
The next step is to configure the SSH server. Open the SSH server configuration file by entering the following command:
Command |
Description |
|---|---|
vi /etc/ssh/sshd_config |
Opens the SSH server configuration file in the vi editor |
Next, scroll down to the line that reads “Port 22” and change the port number to a number of your choice. This ensures that the SSH server listens on a non-standard port and is less vulnerable to attacks.
Also, scroll down to the line that reads “PermitRootLogin yes” and change “yes” to “no”. This disables root login, which is a security best practice.
Finally, save and exit the SSH server configuration file by entering the following command:
Command |
Description |
|---|---|
:wq |
Saves and exits the vi editor |
Step 3: Restart SSH Server
The final step is to restart the SSH server to apply the changes made in the configuration file. Enter the following command to restart the SSH server:
Command |
Description |
|---|---|
service ssh restart |
Restarts the SSH server |
