Connecting to a VPS from a Mac using SSH is a fundamental but highly useful skill for system administrators or users working remotely. This guide will walk you through a simple and efficient way to use Terminal for an SSH connection.
- Preparation Before Connecting
To begin, you’ll need the following information:
VPS IP address: For example, 192.168.1.100
Username: Typically root or another user you’ve set up
Password: Or an SSH key if using key-based authentication
macOS comes with an integrated SSH client in Terminal, so no additional software is required.
2. Steps to Connect via SSH
Step 1: Open Terminal
Use the shortcut Command + Space, type "Terminal," and press Enter. Terminal is the application where you’ll input commands to manage your VPS.
Step 2: Use the SSH Command to Connect
The basic SSH command syntax is:
Example:
root: The username to log into the VPS.
192.168.1.100: The VPS IP address.
Step 3: Enter the Password
Press Enter, and the system will prompt you for a password. Type your password (note that no characters will be shown while typing) and press Enter. If the information is correct, you’ll be connected to the VPS.
3. Handling Common Errors
"Connection refused": SSH service may not be running, or the firewall may be blocking port 22. Check your configuration to ensure port 22 is open.
"Permission denied": Incorrect username or password. Double-check your credentials.
"Host key verification failed": Conflict with an old SSH key. Resolve it with:
4. Useful SSH Tips
Use the exit command to disconnect from the VPS.
If your VPS uses a non-default SSH port (not 22), specify it with -p:
ssh root@192.168.1.100 -p 2222
Set up an SSH key for passwordless login to enhance security.
5. Alternative SSH Clients for macOS
