Install XFCE, TightVNC server, and Firefox web browser. See the Vultr Firewall Quickstart Guide for more information. If you want to avoid the extra complexity of the SSH tunnel described in step 6, you could protect the server with the Vultr Firewall, blocking all traffic to port 5901 except your IP address. See step 6 in this guide for more details. With port 5901 blocked, you'll need to set up an SSH tunnel. If you already have custom firewall rules and only need to add protections for VNC, run the following command to block port 5901. These commands block all connections except SSH. If you choose that option, please set up the firewall name before installing VNC. One option for security is to block the VNC port in the server firewall and tunnel the connection via SSH. Option 1: Use an OS firewall and tunnel connections via SSH

VNC listens on port 5901 by default, and the connection is not encrypted. # adduser example_userĪdd the new user to the sudo group. Then, fill in the other information as desired.

What is Cloud Computing?Ĭloud computing is the delivery of servers, storage, databases, and networking over the Internet (a.k.a. VNC is a desktop sharing system that allows you to remotely control another computer when you use Vultr cloud computing hosting. After installing, you'll have a desktop similar to the Xubuntu distribution. This guide describes how to install the XFCE GUI and connect to it securely with Virtual Network Computing (VNC). In addition, sometimes, you'll want to install a Graphical User Environment (GUI) to use the cloud server as an Ubuntu desktop. When you deploy an Ubuntu server at Vultr, you'll need to perform system administration using the command line.
