Local vs Remote Login
Oftentimes one will login to a remote system/server, from your local machine (PC, Mac, Laptop etc.). Local just means anything that is sitting in front of you.
A server running Linux via AWS, Azure, or Google Cloud is remote and doesn’t usually have a graphical user interface (GUI) just text. This is done using SSH – Secure Shell. Open SSH Daemon (sshd) is a program that runs on the server at all times.
Open SSH Daemon replaced the previous standard Telnet. Telnet was the previous standard and is now legacty because did not provide encryption of data, making it vulnerable to man-in-the-middle-attacks.
SSH Login
First check to see what ip address your local machine uses by entering the following command:
This should return the followining information with the ip address highlighted in yellow.
On the remote server in green below we have an SSHD (ssh daemon) running on the server listening for any incoming connections on the default port 22.
To connect to the remote server enter your username and the ip address as well as your password.
