How to Change the SSH Port on a Linux Virtual Server (Detailed Guide)
Securing remote access to your Linux virtual server is one of the most critical responsibilities of any system administrator or developer. SSH (Secure Shell) is the primary method used to access servers remotely and by default, it listens on port 22. Because this port is universally known, it is constantly targeted by automated bots attempting brute-force attacks. While changing the SSH port is not a complete security solution, it is a highly effective first step in reducing attack surface and noise. In this detailed guide, we’ll cover not only how to change the SSH port, but also why it matters, potential pitfalls, and best practices for maintaining a secure server environment.
