This document discusses Secure Shell (SSH) and how to use it to securely connect to remote servers and transfer files between local and remote systems. It explains that SSH is a secure replacement for older protocols like Telnet. It provides commands for logging into a remote server called "cpu" using SSH, and for copying files between the local and remote systems using secure copy (SCP). It also covers setting up SSH key-based authentication for passwordless login to remote servers.
