I’m confused about SSH and VPNs

SSH is the short term for Secure Socket Shell. It is a network protocol that allows administrators to have a secure way of accessing a remote computer. It also refers to the set or suite of utilities that apply the protocol. Secure Shell gives secure encrypted data communications and strong authentication between 2 computers that are connecting over an unprotected network like the internet.

Network administrators broadly used SSH for managing applications and systems remotely which lets them log in to another computer over a network, move files from one computer to the other, and execute commands. Separate from Microsoft Windows, by default, SSH software is included on the majority of operating systems.

SSH also supports tunneling, forwarding arbitrary TCP ports and X11 connections whereas file transfer can be executed using either of the associated SCP or secure copy or secure file transfer protocols. By default, an SSH server listens to the traditional TCP port 22. The SSH suite is composed of 3 utilities: slogin, ssh, and scp.

They are the secure versions of the previous vulnerable UNIX utilities: rlogin, rsh, and rcp. You don’t need to actually install a VPN software if you want it free. You can have it as an extension or plug-in using the Opera browser. Download the latest version of the web browser from Opera for Windows PC.

Once you have it installed, you can head to Opera VPN Add-ons and select your VPN to install.
