How to Set Up SSH Access on a VPS?
SSH (Secure Shell) is a protocol that allows you to securely connect to a remote device, such as a Virtual Private Server (VPS). SSH access enables server management from anywhere in the world via the command line. This article will guide you through setting up SSH access on your VPS.
First, you’ll need a root account on your VPS. Then, follow these steps:
Step 1: Installing the SSH Server
The first step is to install the SSH server on your VPS. In most cases, you can use your operating system’s package manager. For example, on Ubuntu, you can use the following command:
sudo apt-get install openssh-server
Step 2: Configuring SSH
After installing the SSH server, you’ll need to make some changes to the configuration files. Open the SSH server configuration file in a text editor using the command:
sudo nano /etc/ssh/sshd_config
Change the SSH port if you want to enhance your server’s security. By default, SSH uses port 22. You can also configure access to the server using only an SSH key, disabling password authentication.
Step 3: Restarting the SSH Server
After making changes to the SSH server configuration file, restart the SSH service to apply the settings. Use the following command:
sudo systemctl restart sshd
Step 4: Connecting to the Server via SSH
Now, to connect to your VPS via SSH, open a terminal and execute the command:
ssh username@your_vps_ip
Where username is your username, and your_vps_ip is your VPS’s IP address. Enter your user password, and you’ll successfully connect to your server via SSH.
You now have full SSH access to your VPS and can manage it from anywhere in the world. Happy administrating!
