VNC Functions and Areas of Application

VNCの代替に取り組んでいるサポートチーム

VNC (Virtual Network Computing) was developed in the 1980s as a technique for controlling computers remotely. VNC’s main function is to remotely control a computer (server) from a local computer (client) while displaying the VNC server’s screen content on the local monitor. A VNC session can function on any type of operating system that is installed on the server or client computer. VNC also supports sessions with iOS and Android devices.

An essential element of the VNC viewer is the remote framebuffer (RFB) protocol. Its purpose is to transmit the VNC server’s screen content as well as the local client’s input. The source code was released more than 20 years ago as a free software under the GNU General Public License.

In order to connect to VNC, suitable software is needed for both the server and the client computer. Another requirement is the availability of additional ports. A connection cannot be made if these requirements haven’t been met. There may be additional constraints due to the comparatively large amounts of data that accumulate during VNC sessions. Occasionally, these delays prevent operations from running smoothly.

A VNC Alternative that Doesn’t Need Available Ports

TeamViewer Host - mobile

Unlike with a VNC viewer, you can set up remote sessions with TeamViewer without any upstream port availability. In remote support, for example, this enables you much greater flexibility when clients or employees work from various locations and port availability hasn’t been arranged. For support employees who work with VNC, it often isn’t possible in such cases to establish a connection to the VNC server. When this happens, only limited assistance is possible, resulting in downtime and increased costs.

TeamViewer, by contrast, provides a quick and reliable remote connection regardless of the port assignment or platform. If necessary, you can use the QuickSupport tool for exceptionally fast and straightforward assistance, or set up TeamViewer Host for in-depth support, which even includes the maintenance of unattended PCs and servers. The TeamViewer interface is also user-friendly for those who aren’t IT experts. The integration of chat, VoIP and video calls also enables smooth communication, which makes support particularly efficient.

TeamViewer is More than a Tool for Remote Connections

In contrast to classic VNC software for clients and servers, TeamViewer offers a series of additional administrative functions for remote support: you can establish effective security management by the assigning authorisations and licenses in the management console. This lets you set up and assign guidelines for editing and password entry rights, for example.

For administering complex support tasks you also have the option of using TeamViewer servicecamp. This makes it possible to integrate a ticket system with all the relevant functions for administering requests. You can group requests, prioritise and set up queues.

TeamViewer as an All-in-One Solution for Mobile Working

Through extensive remote functions, universal compatibility and high connection speed, TeamViewer creates the ideal conditions for trouble-free mobile working. TeamViewer goes far beyond the functions of VNC by also providing full access to your office computer. This way, you can not only get access to your data, but also operate programs and print remotely.

TeamViewer is also a versatile collaboration tool. For example, you can create online meetings with colleagues in no time at all. During these you can also share screen content.

Sensitive data remains protected with TeamViewer, regardless of the location. AES-based end-to-end session encryptions and RSA public/private key exchange are the most effective protection against unauthorised access.

Simple set-up with TeamViewer

You can set up TeamViewer remote connections through ports that have already been made available. Unlike when setting up VNC, no additional ports must be made available.

Comprehensive platform connections

As an all-in-one solution, TeamViewer is suitable for remote support and remote access on PCs, servers and mobile devices.

Initiate reboots and installations

Remote connections through TeamViewer make it possible to initiate reboots and program installations on unattended computers.

VNC 기술은 어떻게 작동하나요?

VNC에서는 서버를 통해 화면 픽셀 데이터를 한 컴퓨터에서 다른 컴퓨터로 전송하기 위해 특별 네트워크 프로토콜인 RFB(원격 프레임버퍼)를 사용합니다. VNC 클라이언트는 키 스트로크, 마우스 이동과 클릭 등 사용자 입력값을 서버를 통해 공유합니다. VNC 서버는 로컬 디스플레이 프레임버퍼 내용을 캡처하여 이를 로컬 입력값으로 해석하는 클라이언트에 다시 공유합니다.

VNC는 안전한가요?

VNC에서는 암호가 플레인 텍스트로 전송되지 않기 때문에 초기 연결 및 로그인 시 암호화를 사용합니다. 하지만 VNC가 연결되어 있을 때 암호가 해독되고 해커의 공격을 받을 때 문제가 발생합니다. 이와는 반대로 TeamViewer는 AES 기반 엔드 투 엔드 세션 암호화 및 RSA 공개/비공개 키 교환을 사용하여 무단 액세스를 방지하고 데이터를 항상 안전하게 유지합니다.

VNC와 TeamViewer의 차이는 무엇인가요?

기술 설정 및 보안 측면의 차이 외에 TeamViewer와 VNC 소프트웨어의 차이점은 TeamViewer에서 온라인 협업 및 원격 지원 기능을 사용할 수 있다는 점입니다. 쉽게 말해 VNC는 원격 제어 솔루션인 반면 TeamViewer는 올인원 솔루션입니다. TeamViewer와 함께라면 온라인 회의를 주재하고 TeamViewer servicecamp를 통해 티켓 시스템을 관리하며 기타 많은 기능을 활용할 수 있습니다.
