Secure Shell, also known as ssh, is a secure telnet replacement that encrypts all traffic, including passwords, using a public/private encryption key exchange protocol. It provides the same functionality of telnet, plus other useful functions, such as traffic tunneling.
ssh username @ ipaddress or hostname
Secure Copy, also known as scp, is part of the ssh package. It is a secure alternative to rcp and ftp, because, like ssh, the password is not sent over the network in plain text. You can scp files to any machine that has an ssh daemon running.
Syntax to copy files
scp remote hostname or ipaddress:/filename /localhost folder
Syntax to copy files, folder and subfolder
scp -r remote hostname or ipaddress:/source foldername /destination foldername
