Used by administrators to manage Linux systems remotely, SSH allows logging in, executing commands, and transferring files between computers. It ensures secure communication between a remote host and a local machine.

Method 2: Connect to VPS via. VNC

​
What is VNC?

VNC, or Virtual Network Computing, is a graphical desktop-sharing system that uses the Remote Frame Buffer (RFB) protocol to remotely control another computer’s desktop environment. It allows a user to view and interact with the graphical desktop of a remote system over a network connection. VNC works by transmitting the graphical display updates from the remote system to the client software running on the local system, and it sends user input events (such as mouse and keyboard actions) back to the remote system.
Atomic Networks does not recommend connecting to a VPS via. VNC for production use cases unless it is absolutely necessary. VNC protocol has a large number of security vulnerabilities.
If you are a current Atomic Networks client, you can connect to your VPS via. VNC through the panel at vm.atomicnetworks.co

​
Requirements for Logging into a VPS via. VNC

To connect to a VPS via. VNC, you will need to have the following information:
  • IP Address
  • Username
  • Password
