How to Install SSH Server on Linux

In this guide, we’ll walk you through the steps to install and configure an SSH server on Linux, covering both Debian-based and Red Hat-based systems. SSH provides secure remote access to your system, making it an essential tool for system administrators and anyone working with remote servers.

Installing on Ubuntu/Debian Systems

sudo apt update
sudo apt install openssh-server
sudo systemctl enable ssh
sudo systemctl start ssh

On Fedora, CentOS, and RHEL

sudo dnf install openssh-server
sudo systemctl enable sshd
sudo systemctl start sshd

The SSH server listens on port 22. If your Linux server is behind a firewall, make sure to open TCP port 22 to allow SSH connections.
