The Check the Video Hook Driver button is used to check the functionality of the capture driver. You only need to use it if at least one client is connected to the server. Otherwise, a message will always be displayed that the driver is not active. This is what the message that the driver is installed and functioning looks like:. For the server to be accessible via the Internet, the tcp port forwarding must be configured on the router.

This port must also be open in the server's firewall. If you are using only the built-in Windows Firewall, no additional action is required, the required permissions have already been created during installation. Download repeater. There is only one file in the archive - repeater. Run repeater. An icon will appear in the tray. We make a right click on it and select the Settings item in the menu:. The next step is to open tcp port in the firewall.

In the settings of the router, you need to create a rule for forwarding the tcp port to the computer where the repeater is installed. Finishing touch. For the repeater to be constantly available, it must be started as a system service. To do this, open a command line as administrator, and run repeater. To uninstall the service, run repeater. How it works. The user unpacks the archive, launches the program and connects.

As a result, you get access to the console of the remote computer. Because the connection is initiated by the remote computer, there is no need to configure the firewall and router on the remote network. It contains a subfolder data. Now you need to edit the helpdesk.

This file is responsible for the connection manager interface:. Remote help q2w3. Connection established! If you will create your helpdesk. Now we open the properties of the shortcut. Clear the "Working folder" field, it should be empty. In the field, write the following command:. It remains to prepare your computer to receive a connection. UltraVNC Viewer must be run in listen mode.

It is also unforgettable to open the tcp port in the firewall and set up forwarding of the same port on the router if, of course, one is present on your network. Please note that connection parameters quality, etc. VNC Viewer is a program for remote access to the desktop of your home or work computer. We will look at how to install it, how to use it, and where to download it.

Based on the name of the VNC Viewer application, many users can immediately guess which class software it refers, for example, by analogy with the well-known TeamViewer package. However, ordinary users may encounter such a utility for the first time, so it is worth dwelling separately on some questions related to how and what modification of the program is better to install, how to configure the application for optimal operation, how to use the VNC Viewer, "squeezing" the maximum of it out of the application.

The old counterparts of this program is Radmin, which is known to almost everyone who has worked in system administration before. Control is carried out by transmitting keystrokes on the keyboard and mouse movements from one computer to another and relaying the screen contents through a computer network. There are client and server implementations for almost all operating systems, including Java including the J2ME mobile platform. Multiple clients can connect to one VNC server at the same time.

The most popular uses for VNC are remote technical support and access to a work computer from home. The name originated from the Videotile thin client computer network, which was an LCD display with pen input and a fast ATM network connection. VNC has two parts: a client and a server. Server is a program that provides access to the computer screen on which it is running. Client or viewer is a program that receives a screen image from the server and interacts with it via the RFB protocol.

RFB English remote framebuffer is a simple client-server network protocol of the application level for remote access to a graphical desktop of a computer, used in VNC. Since it works at the framebuffer level, it can be used for graphical windowing systems, such as the X Window System, Windows, Quartz Compositor. At the beginning of its development, RFB was a relatively simple protocol based on graphic primitives: "put a rectangle of pixel data at a given coordinate position.

This scheme, in its primitive form, consumes a lot of traffic. Various methods are used to reduce the load on the channel. There are various encodings - methods for determining the most efficient way to convey these rectangles. The RFB protocol allows the client and server to "negotiate" which encoding to use.

The simplest encoding method supported by all clients and servers is "raw encoding", in which pixels are transmitted in left-to-right, top-to-bottom order, and after the initial screen state is transmitted, only the changed pixels are transmitted. This method works very well for minor changes to the image on the screen movement of the mouse pointer on the desktop, typing under the cursor , but the channel load becomes very high when a large number of pixels are changed at the same time, for example, when watching a video in full screen mode.

Over the course of its development, the protocol has acquired various additional functions and options, such as file transfer, compression, security. Each port represents a corresponding X Server screen ports to are associated with screens: 0 through: 6. Java clients available in many implementations that use the embedded web server for this purpose, such as RealVNC, are associated with screens in the same way, but on a port range from to Many Windows computers can only use one port due to the lack of multiuser properties inherent in UNIX systems.

For Windows systems, the default screen is: 0, which corresponds to port It is also possible to connect back from the server to the client. In this case, the client is switched to listening mode and the connection is initiated by the server on the client's TCP port Initially, VNC does not use encryption of traffic, however, the password is not transmitted in the clear text during the authentication procedure, but a challenge-response algorithm with DES encryption the effective key length is 56 bits.

In many implementations there is a limit of 8 characters for the length of the password, and if its length exceeds 8 characters, then the password is truncated, and the extra characters are ignored. IPsec technology is supported by the vast majority of modern operating systems and is used both when connecting via the Internet and in local networks.

To begin with, let's briefly dwell on what this software product is, consider what it is intended for. Based on the above analogy, we can say that a VNC client is a universal application that allows you to organize access to a remote computer in a matter of minutes.

That is, this program can be attributed to the class of RDP applications designed to connect to a remote desktop. However, the matter is not limited only to access to remote computers, since the program itself has many more additional features:. It should be noted right away that Virtual Network Computing VNC technology has one more indisputable advantage when compared with analogs.

The fact is that it has the ability to install the server and client parts depending on which type of connection will be used in the future , plus, fine-tuning the software for each installation option in order to ensure maximum performance.

Before proceeding with the installation, you need to decide on the choice of the VNC client modification that you intend to install. Firstly, the program itself is cross-platform, it can be installed in almost all known stationary and mobile operating systems. Thirdly, you should decide on the type of client to be installed the server part is used to organize a connection from the central machine to the child terminals, and the client part is used to connect from the child machines to the central server.

The last point is at the request of the user. Do not download this program from other sources, because there it can be infected with a virus, it is especially problematic if it is a ransomware virus that encrypts all data on your computer and which is very difficult to recover, and often even impossible.

Now let's go directly to the installation of the selected software product. Note that for almost all modifications, the installation process looks the same. To start the installation in Windows versions 7 and higher, the VNC client installer file is launched exclusively with administrator privileges in the PCM menu, the option to run as administrator is selected. There is nothing unusual about the installation process itself.

The user needs to select the preferred language, accept the terms of the license agreement, specify the installation path it can be left unchanged , add an icon to the "Desktop" at one of the stages, and then simply press the button to start the installation.

Let's assume that the program is installed, and the user launches it for the first time. Initially, VNC Viewer settings are not very complicated. At the first start, a window will be shown in which you can select the desired action. But we will proceed from the fact that we need to carry out the connection ourselves. First, through the file menu, select the New Connection item, and then in a new window enter the IP address of the remote terminal or the full name of the computer the address can be found on the connected machine using the properties of the Internet connection or command line with the ipconfig command, and the computer name can be viewed in the system properties.

After that, a window for asking for a password will appear, in which you need to enter the desired combination. If the combination matches the set to remote computer the password will appear the remote "Desktop". We figured out how to use the VNC Viewer to create a connection. Now a few words about the preferred settings. If you look closely at the window for creating a connection, you will find a tab for experts.

If you select in these settings, for example, the preferred compression algorithms for transmitted and received data, then you can significantly reduce the load on the central processor and optimize the use of Virtual Network Computing technology even for networks with a bandwidth of kbps. For graphics, it is recommended to set a high compression level Compression Level with a minimum quality JPEG Quality , and as an additional optimization, activate a decrease in the number of colors Restricted Colors or bgr In addition, it is worth noting that a single terminal can use a connection to multiple machines based on the base port through a display parameter.

By default, the primary display has a value of "0", while for all others it is increased "1", "2", etc. Accordingly, the port , , etc. You can set this setting on the router or register on the service portal on the Internet. In this case, the service will transmit to the installed client all information related to changing the IP of the connected computer. Basically, failures can be associated only with the fact that at the moment there is simply no Internet connection on the computer or the corresponding port is busy, which is used by the program by default.

Sometimes you may notice blocking by antiviruses and firewalls. But these problems are solved quite simply. Among the main methods for eliminating possible failures when trying to establish a connection, we can recommend the following:. That's all, in short, how to use the VNC Viewer. As you can see, there is nothing particularly complicated here. In conclusion, it is worth noting that in some cases it is advisable to use non-passwords that are set directly in operating systems , and in advance to enter the registration record in the client itself, having previously created it on a special resource.

In this case, you will not be dependent on Windows accounts. In everyday life, a situation often arises when it is necessary to install or configure programs on computers that are located in a neighboring office, office or in another city. Running around offices and offices is certainly good for your health, especially if you have to maintain over 30 computers : but we will not mock ourselves like that, we will organize and configure remote access to a PC.

There are a lot of programs for remote access and each one stands out in its own way. Remotely controlling a computer sounds intriguing, but only for those who have not experienced it before. In fact, this service appeared a long time ago and is widely used by professionals. Many developers of various programs initially implement this feature in their products so that they can quickly help customers cope with software problems or settings. With high-speed internet, this is very simple and fast.

However, sometimes there is a need to help acquaintances, friends or relatives, especially if these are older people who first took a mouse in their hand. Also, from time to time, you urgently need to get to your home computer, for example, when you forgot to download an important presentation to a USB flash drive, or, being in another city, you want to show your friend your photos from your last trip to the Urals.

UltraVnc Is another program for remote computer control. Advantages: is free and supports both Windows and unixOS e. Disadvantages: a bunch of scary English settings. So the eyes are afraid, but the hands are doing. Download the latest version from the official website www. We launch. We select server server and viewer viewer.

The server is installed on those computers to which we will connect, and the viewer on those from which we will connect. Allow Loopback Connections - allow the connection through the "loop" as if not himself for the test. We leave. View-Only Password - password for viewing only in English. It would be nice to make it different from VNC. Require MS Logon - applies Accounts windows. We do not put a tick. I am not exhibiting anything.

Field "Query on incoming connection" - "Incoming connection request". Asks the user if he allows the connection to him. Display Query Window - message display time. If the user didn't click anything: — Refuse - connection failure. Field "Multi Viewer Connections" - "Simultaneous connection of several clients". The field "Misc. We celebrate. Check the box. This option is malfunctioning, so I uncheck the box. Use if with the first variant of the problem. It malfunctions, but a very useful feature when you need to view video cameras, for example.

Not necessary. Open "Settings" and we can change them here. Allows you to take screenshots of your desktop. Field "Capture Options" - "Capture options". Field "Advanced" - "Advanced". Use System HookDll - the option makes sense on Windows 9x. Video Hook Driver - use a video capture driver. Provides the best performance on Windows XP, Vista, 7. Show Primary Display - show the first screen.

Show Secondary Display - show the second screen. Capture Alpha-Blending - video image capture. Remote aer while connected - disable Aero when connected. Remote wall paper while connected - disable desktop wallpaper when connected. The "Quick Options" field configures the connection speed. We leave the car. There are also settings: — View Only - view only. Only when peeping. We put it. In general, we do not need anything else, so we enter the IP address of the computer how to find out the IP address of your computer see , on which there is an already configured server UltraVNCServer and click " Connect ".

After asking for a password, we get to the computer we need. There are situations when the functionality of the RDP client for Windows may not be enough. For example, when you need to connect to a user session without interrupting it.

It may not always be rational to buy commercial versions of such programs. In this case, UltraVNC will help - free program open source for remote desktop access. The first step is to install the UltraVNC server on your computer, to which you want to connect remotely.

Launch the distribution kit and leave the UltraVNC server checkbox ticked. If you want the server to start when Windows starts, then in the next step you can install it as a system service. When connecting to the UltraVNC server via the Internet, it is recommended to use the encryption module. The fact is that by default the VNC protocol does not encrypt data and they are transmitted in clear text.

Consequently, data can be intercepted by intruders. The link to the encryption plugin can be found on the program page. After installing the server, find the UltraVNC server icon in the tray next to the clock, right-click and select the "Admin Properties" item. Here you need to set the password for the connection "VNC Password" and the password for the view mode.

Passwords must be different, otherwise only view mode will be available. To configure the plugin parameters, click the Config button. Here you can select the appropriate encryption technologies for the connection. It is not necessary to generate keys, they are generated automatically when the connection is established. If an encryption plugin is used on the server, then the client must have it installed as well. Next, enter the IP address of the server or its name in the local network.

To save the settings as permanent, at the bottom, check "Save connections settings as default". To connect to a remote desktop via the Internet, you need to open a port and configure NAT address translation. By default, TCP port is used. However, it can be changed in the server settings. My secret. The important points start from the installation type selection screen: Several options are available: Full installation - full installation.

Create UltraVNC desktop icons - create shortcuts on the desktop. Click Next, after downloading the add-ons, complete the installation. Reboot if necessary. The driver. To install under bit Windows 7, open the Vista folder this driver works fine under the Seven too.

Next, run the install. Now you can proceed to configure the basic parameters of the UltraVNC server. Setting up UltraVNC. When you don't put 1 the filetransfer is done as user "system". User system don't have access to mapped drives and pose a security issue Using this option you also can define a custom blank by placing a file "background.

The key processing is different and sometimes solve issue's with special keys. Multiple match terms may be specified, delimited by the ":" character. Terms appearing later in the template take precedence over earlier ones. Terms beginning with the "? The QuerySetting option determines the precise behaviour of the three AuthHosts options. If the user is logged on, but has his screensaver on you normal can't get access as "QueryIfNoLogon" find a logged user.

Disable on viewer connect, reenable on exit. Makes Windows Vista, Windows 7 faster. Make sure this directory is writable by system no mapped folder. Any positive integer is valid. Zero indicates that no debugging information should be produced and is the default.

Note that this option is only available when configuring the Default Options or when configuring a new connection, not when the connection is already active. If the Full-screen mode checkbox is ticked then VNC Viewer will attempt to take over the entire local display in order to show the remote desktop.

The full-screen setting can be set as a default, used for new connections, and changed once a connection is active. The F8 Menu also provides a shortcut to toggle full-screen mode. This means that the cursor responds more quickly to mouse movemements and makes VNC connections over slow networks appear faster. Over faster networks, or for personal preference, this local rendering may be disabled by unticking the Render cursor locally checkbox. If dynamic resizing is not supported by both viewer and server then changes to the dimensions of the remote desktop may cause the VNC connection to be closed.

Dynamic desktop resizing can be disabled if it causes problems on your system. Some third-party VNC software use non-standard version numbers which may cause incompatibility issues. Note that this option may be set as a Default Option, or when making a new connection, but cannot be changed once a connection is active. By default, VNC Viewer will cause a sound to be produced whenever a bell event is received from the server.

This option allows bell events to be ignored by VNC Viewer. When an error occurs that causes the VNC connection to be closed, VNC Viewer can offer to reconnect to the server, using the same username and password. This option applies only to connections made from viewer to server, and not to reverse connections. VNC Viewer stores a set of preferred defaults for all new connections in the user's registry. Special purpose settings, or settings specific to particular hosts can be maintained by using VNC Configuration.

If the VNC session was started by loading settings from a VNC Configuration file then the original settings are reloaded from that file. If the VNC session was started by loading settings from a VNC Configuration file then the current settings are saved back to that file. The current settings will then be saved to the specified file.

In addition to the settings described above, the VNC viewer supports several advanced options. For a full list of options, run vncviewer -help. If the MenuKey option has been used to specify a different key then we still call it the F8 Menu, to keep things simple The F8 Menu provides the same set of available functions as the VNC Viewer window's normal System Menu, namely those allowing the window to be minimized, maximized, moved or closed.

The Full screen menu item allows full-screen mode to be toggled on or off directly, without having to use the Options dialog. See the description of the Full screen setting in the Options page for more information. This affects the interpretation by the server of keypress sent while either or both of these menu items is activated.

This can be useful to send keypresses that would otherwise be intercepted locally by the operating system. To send an F8 keypress to the server, you can bring up the F8 Menu locally and select the Send F8 menu option. Note that if the MenuKey option has been changed to a different function key then this menu item will reflect that change. If the MenuKey has been disabled entirely then this option will not be present. The Ctrl-Alt-Del key sequence is intercepted by the operating system for use as a Secure Access Sequence and so cannot be captured by the VNC Viewer for transmission to a remote server.

This is available primarily on European versions of the operating system. Requests a full screen update from the VNC Server. Use this if you experience any unexpected visual artifacts. The New Connection The VNC Viewer process will not quit until both windows have been closed. This may affect the behaviour of scripts which launch VNC Viewer.

This causes the Connection Options dialog to be displayed, allowing the settings for the current connection to be modified. The Connection Info dialog displays information about the remote host, pixel format, line-speed estimate and protocol version.

If you don't know what any of this means then don't worry - it's all safe to ignore! The main use of the Connection Info dialog is to help in diagnosing any problems you might encounter while using VNC Viewer. If you have difficulties which are not covered by this document, try reading the Knowledge Base. There are also some pages to help with troubleshooting.

Attention This is not our current website. Download Documentation. If the VNC server's Display Number is non-zero then the display number can be specified by adding a colon to the server's IP address or name, followed by the display number: If the VNC server is using a non-standard port number to accept connections then this is specified by adding two colons to the server's address or name, followed by the port number: Encryption is not currently supported by VNC Open.

Connecting using. The Options The Options dialog consists of a number of pages of options, grouped according to their function. Colour level The Colour level box controls whether VNC Viewer should request as many colors as it and the server can handle, or one of a predefined set of lower-color, less bandwidth-intensive levels.

Only use protocol version 3. Save As Other Settings In addition to the settings described above, the VNC viewer supports several advanced options. Clicking anywhere outside the F8 Menu will cause it to go away again. Additionally, some VNC-specific actions are available: Full screen The Full screen menu item allows full-screen mode to be toggled on or off directly, without having to use the Options dialog.
