xrdp

In that article I'll show you, how you can get a remote access to a Ubuntu computer. I mean remote desktop access, because I don't think you can have any questions with access to terminal, as I think ssh is well known to everyone.

I'll show how to get access with the hel p of VNC server and xrdp. Because if you want to make a connection from Windows computer, I think that VNC will work, to put it mildly, not so fast. Also youl need to install VNC client, if you will use simple VNC server, but there are situations when you cannot install additional software on computer, so we will configure everything so that you don't need to install anything. after the steps taken, you can 1) connect to your remote computer with clear VNC protocol; 2) connect to remote computer with RDP, and then from inside RDP session connect to desktop with VNC - that will allow you not to install additional client to computer from whitch you are connecting.

There is a single requirement to that scheme - you must have a real IP, or use VPN or SSH tunnel.
