Virtual Network Computing (VNC) is software that is used to take control of remote computers. It is a very commonly used tool that makes supporting end-users and server environments much easier by allowing help- desk technicians and system administrators to remotely control computers. VNC requires two computers. The remote computer is known as the server, while the computer used to gain access to the server is known as the VNC client or viewer.
The server is the machine to which the user wants to connect. Normally, this is a remote computer that requires a change in settings or troubleshooting for a problem. After installing VNC on this computer, a password should be enabled so that system administrators can prevent unauthorized users from hacking in and stealing sensitive information. Having VNC on this computer allows users to control the machine remotely. When connected, the system administrator uses their own mouse and keyboard as if he or she were using the peripherals on the remote computer.
The client or viewer is the computer that the user makes the connection with. Much like the server, the client must be configured with the same VNC software in order to make the connection. Often this is a Windows® computer, as Windows is the dominate operating system on the market today.
Users must configure the client similarly to the server in order to make a connection. The startup screen will present you with several options, but the two to check are the port and password options. Open this area in the configuration menu. If desired and connecting through a local network, you can opt for Windows authentication, but a password is preferred when connected over the Internet. Users may also opt to keep the default port, but a separate one can be chosen for more security.
After configuring both the server and client, techs can connect to the remote computer using VNC. From there the tech can control the remote computer just as if he or she were sitting directly at the computer’s keyboard. This is useful in several different scenarios. Techs might use VNC to troubleshoot end-users’ computers at remote locations. They may also use it to provide training to end-users at remote locations. Server administrators often use VNC to manage servers housed in datacenters.
Remote Framebuffer Protocol
Often shortened to RFB, the remote framebuffer protocol is what enables remote access. There are two modes of operation for this integral part of VNC. One allows the computer to show what the other computer has on its screen, and the other is "virtual," meaning it will not appear on the screen.
The protocol uses a thin client system, meaning that the local computer is nothing more than a screen to display a desktop and peripherals like the keyboard and mouse to function as input devices. This client accesses the CPU and the hard drive of the remote computer.
Though the protocol is designed to provide insight on the other screen, the actual concept removed the need to have the other computer display exist to be viewed from a distance. This is why the market has many VNC programs available that allow different simultaneous functions on a computer.
The protocol originally comes from the Olivetti Research Laboratory, and many of their developers later went on to form another company central to providing VNC services. Since then, the remote frame buffer protocol has become an open standard for the public, meaning anybody can use it and make programs with it.
Benefits of VNC and Dameware®
As a cross-platform solution, VNC is very robust and functional. With the number of problems that other programs face, having interchangeability is definitely an advantage. Most of the corporate world uses Windows, though some may prefer Mac®, while many IT setups prefer to use either Linux® or UNIX®. This normally creates incompatibility, but DameWare Remote Support allows you to connect Linux, Mac OS® X, or Windows computers from just one console.
DameWare developers realized the value of VNC and incorporated it into the DameWare Remote Support console. Within the DameWare software console, users can also choose to connect to remote computers with remote desktop protocol (RDP), the native remote connection tool in all Windows operating systems since Windows XP. DameWare developers have also created their own proprietary connection tool called Mini Remote Control Viewer to make connections to Windows computers.
Regardless of which connection type you choose from the console, you will have access to functions like in-session chat, file-transfer, and one-click screenshots. DameWare Remote support makes managing a mixed-OS environment much easier for help-desk professionals and system administrators.
In addition to these powerful remote control features, DameWare Remote Support includes tools that allow system administrators to perform Windows administration tasks remotely from the same console. From the console, sys admins can view the event logs of computers without having to take full control of them. Similarly, sys admins can restart services, view processes, manage disks and printers, view the software installed on Windows computers remotely.
