Using SSVNC and SSH - am I safe?

  • 772

I connect from one computer to another (both Ubuntu) via SSH using an SSH-key. Now I also installed a vnc server on one of them (vnc4server) and use ssvnc (downloaded from the software center) to connect. In the viewer options, I choose "Use SSH" but nothing else. (except for entering a vnc password)

Is that a safe way of working remotely? Is the transferred data (screen information, keyboard input, etc) encrypted? If not, what is the SSH-option for?

Sorry about not knowing about anything. I am just wondering whether I really need to go through all of What's the best way to secure a Teamviewer/X11/VNC connection?

vnc

    The short answer is, yes!

    When SSH is used with VNC, it means first an SSH connection is established, then the VNC connection is "tunneled" through the SSH connection.

    Having said that I have never used ssvnc, but the name seems to suggest it uses SSH and VNC protocols. Then it stands to reason that it uses SSH tunnelling.

    I use Remmina, a versatile remote connection tool that allows using various protocols, including SSH, VNC and both of them together.

    The question and answer you linked has some good advice. You can create an SSH tunnel on your own, and then use VNC separately to connect to 127.0.0.1. But remmina and presumably ssvnc will do all that for you.

    Hope this helps
