How to connect via SSH
From Pulsed Media Wiki
Connecting to Your Server (SSH)
The first step is to connect to your server using SSH (Secure Shell). You'll need an SSH client (like Terminal on macOS/Linux or PuTTY on Windows) and your server's IP address, username, and password (or SSH key).
ssh your_username@your_server_ip
After running this command, you'll be prompted for your password (unless you're using SSH keys).
