Hello. I have a question. I followed a tutorial from digitalocean in order to start a VNC on linux (ubuntu). First 2 attempts was full of fails, but this attempt was a kind of succesfull. I installed vnc and after it, I could see the desktop, work with firefox from the console on digitalocean, but I can't connect to it with tightvnc. The cursor is not sync on site console and I have a bit of lag on it, so I wan't somehow to connect to it from a third-part application like tightvnc. When I try to connect to it with IP::5901 or IP:5901 I get: target machine actively refused connection.
I think that I need somehow to make permissions for accessing this droplet from outside the localhost.

Thanks.
