Simplify Remote Server Access: Master SSH Config on macOS

To access a remote server via SSH, use the command ssh username@ip_address, e.g., ssh [email protected], then enter the password.

On macOS (similar steps apply to other operating systems), navigate to the SSH directory with cd ~/.ssh/. If a config file is absent, create it using touch config and edit it with your preferred editor.

Add the following content to the config file:

Host jhd
HostName 1xx.1xx.1xx.67
User root
IdentitiesOnly yes

The fields mean:

Host : a nickname you can use later to refer to this server.

HostName : the server's IP address.

User : the login username on the server.

IdentitiesOnly yes : a fixed configuration option.

After saving the file, you can connect with a short command: ssh jhd Enter the password when prompted, and you will be logged into the remote host.
