What is SSH?
SSH, which stands for Secure Shell, is a widely used protocol for securely accessing and managing remote servers or devices over an unsecured network. It provides a secure channel for data communication by encrypting the connection between a client and a server. SSH allows users to remotely log in to another system, execute commands, transfer files, and perform other network services securely. It's commonly utilized by system administrators, developers, and individuals needing secure access to remote system
What is SCP?
SCP uses the same authentication and security mechanisms as SSH, making it a secure method for copying files between computers. It's often employed as a command-line utility and is compatible with various operating systems, allowing users to securely transfer files while maintaining data confidentiality and integrity.
SSH connection using the command line, you typically use the ssh command. Here is a basic example:
Replace username with your username on the remote machine, and hostname with the actual IP address or domain name of the remote server
If you need to specify a port other than the default (22), you can use the -p option:
Replace PORT_NUMBER with the specific port number you want to use.
If you're using key-based authentication, you can add the -i option to specify the path to your private key file:
You can also include additional options and parameters based on your specific needs, such as enabling compression (-C), running a specific command on the remote server (ssh username@hostname command), or enabling verbose mode (-v or -vv for increased verbosity)
Upload file using SCP

Overall, SSH connections and SCP uploads offer a robust solution for securely transferring files, particularly in environments where data confidentiality and integrity are paramount. By following best practices for key management and access control, users can ensure the security of their file transfers while benefiting from the convenience and efficiency of these technologies.
