📖Introduction

In this introduction, we will provide you with an overview of what SSH is, why it is essential, and how installing an SSH server on Debian 7 can benefit you.

What is SSH?

Secure Shell (SSH) is a network protocol used to encrypt traffic between a client and a server. It is widely used to enable remote login and file transfer. SSH provides a secure and encrypted connection that allows users to access their servers securely from anywhere in the world.

Why is SSH important?

SSH is essential because it provides a secure way to access your server remotely. Without SSH, hackers could intercept your traffic and gain unauthorized access to your server or personal information. With SSH, all traffic between your device and the server is encrypted, making it safe from prying eyes.

How can installing an SSH server on Debian 7 benefit you?

By installing an SSH server on Debian 7, you can access your server remotely and securely. You can also transfer files between your device and the server easily. Additionally, SSH allows you to run commands on the server without being physically present at the server’s location.

Requirements

Before we begin, there are a few things you need to have:

Item	Description
Debian 7 Server	You need to have a Debian 7 server set up and running.
Root Access	You need to have root access to the server.

Installation Steps

Now that the requirements are met, let’s dive into the installation process.

Step 1: Update and Upgrade Server

It is always a good practice to update and upgrade your server before installing any software. To do this, run the following command:

sudo apt-get update && sudo apt-get upgrade -y

Step 2: Install SSH Server on Debian 7

Now that your server is up to date let’s install the SSH server. To do this, run the following command:

sudo apt-get install openssh-server -y

Step 3: Configure SSH Server

After installing the SSH server, we need to configure it to accept connections. To do this, open the SSH configuration file using the following command:

sudo nano /etc/ssh/sshd_config

In this file, you can make changes to the SSH server’s configuration. Ensure that the following lines are uncommented:

Port 22

PermitRootLogin yes

Save and exit the file.

Step 4: Restart SSH Server

After modifying the SSH configuration file, restart the SSH server to apply the changes using the following command:

sudo service ssh restart

Advantages and Disadvantages of Installing SSH Server on Debian 7
