How To set up SSH Server on Linux - 4 Steps ★ All Host

Table of Contents

You are in luck if you want to install an SSH server on your Linux computer and you are looking to do so. You can have an SSH server up and operating in no time at all with only a few easy steps, and it will be completely configured. In this tutorial, we will cover everything you need to know to get started creating your own SSH server so that you may securely transfer files.

How To set up SSH Server on Ubontu (Linux)

Let’s look at a short but informative step-by-step instruction, consisting of 4 points.

Step 1 – Installing OpenSSH Server

The first step in setting up an SSH server is to install the OpenSSH Server package. This package contains all the necessary software for running an Secure Shell host on your Ubuntu machine. You can install the package by running the following command in your terminal:

sudo apt-get install openssh-server

This command will download and install the necessary software to your machine.

Step 2 – Configuring the SSH Server

After installing the OpenSSH Server, the next step is to configure the host. This involves editing the sshd_config file, which is located in the /etc/ssh/ directory. You can edit this file by running the following command in your terminal:

sudo nano /etc/ssh/sshd_config

This will open the sshd_config file in the nano text editor. Here, you can make changes to the configuration settings for your Secure Shell host. Some of the settings you may want to consider changing include the default port, the allowed users, and the authentication settings.

Step 3 – Enabling SSH in Linux

Once you have configured the SSH server, the next step is to enable it. You can do this by running the following command in your terminal:

sudo systemctl enable ssh

This command will enable the SSH server to start automatically at boot time.

Step 4 – Testing the SSH Server

After enabling the S.S.H. host, the final step is to test it. You can do this by running the following command in your terminal:

ssh user@host

Replace “user” with your username and “host” with the hostname or IP address of the machine you want to connect to. If everything is set up correctly, you should be prompted for your password and then connected to the remote machine.

Requirements that you will need to meet in order to run an S.S.H. host on Linux

In addition to the steps outlined in the previous answer, there are a few requirements that you will need to meet in order to run an S.S.H. host on Linux:

A Linux machine

You will need a machine running Linux in order to run an SSH server.

Administrative privileges

You will need administrative privileges to install and configure the necessary software.

Internet connection

In order to connect to your SSH server remotely, you will need a reliable internet connection.

A static IP address or domain name

If you plan to connect to your SSH server from outside your local network, you will need a static IP address or domain name that points to your machine. This will allow you to connect to your host from anywhere in the world.

Firewall configuration:

You will need to configure your firewall to allow incoming connections on the SSH port (usually port 22). This will ensure that your SSH server is accessible from the internet.

By meeting these requirements and following the steps outlined in the previous answer, you can set up and run an SSH server on your Linux machine.

In conclusion, the process of establishing an SSH server on Linux may be described as being relatively straightforward. You may have a fully functional SSH server up and running in no time at all if you just install the OpenSSH Server package, configure the sshd_config file, enable SSH in Linux, and test the S.S.H. host. Before enabling the SSH host, just be sure to follow each step in the process very carefully and ensure that your configuration settings are correct twice.
