I nearly always connect like this: ssh -i ~/my_private_key SCP and EC2 using private keysĪt first I didn’t have a simple way to upload files from my laptop to my EC2 instance. We always use private keys to login rather than passwords. We often use RightScale on top of EC2 to manage things.

Some kind of FTP client ( FileZilla, CyberDuck, etc.I have used Amazon EC2 for a few years.

Please check in the security group assigned to this instance. If you don’t have it, then ask your system administrator/DevOps or whoever is responsible for managing these machines/instances on AWS. For you to get connected, you must have that private key with you. On AWS, when you add a new ec2 instance it is added to a VPC (virtual private cloud), and anyone outside that VPC trying to access that machine (and sometimes within that VPC) will need a private key. In plain English, it is a protocol (just like HTTP for transmitting hypermedia documents) using which you can communicate securely with a server. SSH operates as a layered protocol suite comprising three principal hierarchical components: the transport layer provides server authentication, confidentiality, and integrity the user authentication protocol validates the user to the server and the connection protocol multiplexes the encrypted tunnel into multiple logical communication channels.

SSH applications are based on a client–server architecture, connecting an SSH client instance with an SSH server.

Its most notable applications are remote login and command-line execution. The Secure Shell Protocol ( SSH) is a cryptographic network protocol for operating network services securely over an unsecured network.
