Client computer typically a laptop or desktop running VNC Viewer. Host computer typically a workstation or server running VNC Server. Router exposing a public network address for Internet connections to the host computer. You can run applications, change settings, and access data on the host computer exactly as you would be permitted to do were you sitting in front of it. See a picture. Note: By default, VNC Server permits other users to connect to the host computer at the same time as you. You may be sharing control.
VNC remote access and control software solves different problems for users with different requirements, from the family member troubleshooting computer problems over the Internet to the system administrator configuring devices remotely in an enterprise environment. To find out how to get the information you need from this Guide, see What to read next on page Getting the computers ready to use Before you can establish a connection, certain operations must be performed on both host and client computer.
This section addresses the client computer user and assumes the same person is able that is, is physically present and has sufficient privileges to configure the host computer as well. If not, contact a system administrator or a host computer user. Note: Some operations need only be performed once. Others must be performed before each connection. Setting up the host computer 1. Ensure the host computer is turned on, has a functioning operating system, and is connected to a network to which the client computer can also connect.
This can be: — A private network such as a LAN or VPN, if both computers are co-located at home or in a typical small office environment. Download and install VNC from www. The credentials of a user with administrative privileges on the host computer are required. If you are connecting over a public network such as the Internet, it is very likely the host computer will be protected by at least one firewall.
If so, each must be configured to allow network communications through to the port on which VNC Server is listening, which is by default. See Allowing network communications through a firewall on page 31 for more information. If you are connecting over a public network such as the Internet, it is very likely the host computer will be protected by at least one router.
If so, each must be configured to forward network communications through to the port on which VNC Server is listening, which is by default. See Configuring a router to forward network communications on page VNC User Guide 11 Chapter 1: Introduction 5.
Make sure VNC Server is running on the host computer and that it can accept incoming connections. Find out the network address of VNC Server. See Connecting within a private network on page 27 for more information. Find out the credentials required to authenticate to VNC Server. By default, if you are connecting to: — VNC Server Enterprise or VNC Server Personal , you require the user name and password of a user account with administrative privileges on the host computer.
Note at least one account on the host computer must have a password set; see Authenticating using host computer user credentials on page 98 for more information. For more information, see Authenticating using a VNC password on page Note: If you cannot perform these operations and a host computer user is present, you may be able to jointly perform a reverse connection.
See Establishing a reverse connection on page for more information. Setting up the client computer 1. Ensure your client computer is turned on, has a functioning operating system, and is connected to the same network as the host computer.
Download VNC Viewer from www. If you do this, VNC Viewer can be started from the menu system of most operating systems, which may be more convenient, and in addition you can save connections to VNC Address Book.

VNC User Guide 13 Restrictions The credentials you enter to log on to the host computer cannot be used to authenticate to VNC Personal Edition. Note under Windows, there are also certain restrictions when connected to version 4. In particular, connections cannot be encrypted. See Connecting from mobile devices on page You do not require the credentials of a user with administrative privileges on the host computer in order to use VNC Viewer for Java.
VNC User Guide 15 See Changing the encryption rules on page See Relaxing the authentication rules on page Chapter 1: Introduction What to read next RealVNC remote control software can be used in many different ways to solve many different kinds of problem. There is no such thing as a typical RealVNC user or remote control session.
For example, you may be sitting in front of the client computer and want to know how to use VNC Viewer to control a remote host.
Or you may be sitting in front of the host computer and need to know how to set up VNC Server for multiple incoming connections.
You may be connecting within a corporate network, in which case a system administrator might be available to help with connection issues. Or you may be helping friends or family over the Internet, and have to negotiate firewalls and routers on your own. RealVNC remote control software is designed to be as useful out-of-the-box to as many people as possible. However, there is virtually no limit to the ways in which it can be configured to suit your requirements and environment.
Some chapters in this User Guide are targeted at more experienced users, likely to require the power of changing options — system administrators setting up VNC Server for virtualization or remote configuration, for example.
Other chapters, especially the first two, should be useful for all users. To learn more about security, and how to relax the rules if you consider it safe to do so, read Chapter 7 Making Connections Secure on page Note: This chapter assumes both host and client computers are set up correctly. For more information, see Getting the computers ready to use on page Connecting is usually a straightforward process but because computer networks must be secure, problems can occasionally occur.
This chapter offers help for the most common connection issues but it may also be necessary to consult the RealVNC web site, or contact Technical Support. Alternatively, if you are connecting within a private network such as a corporate Local Area Network LAN , consult your system administrator. If you do not have access, contact your system administrator or a host computer user.
Note administrative privileges are required to perform this operation. Note: If no menu system or search facility is available, open a Terminal window, run the command vncserver-x11, and press the ENTER key.
Note you should not do this as a user with administrative privileges. If VNC Server is not licensed, or is not configured correctly, the status bar turns red. Click the Show button that appears, and follow the instructions. For more information, consult Troubleshooting connection on page For more information, see Setting up the client computer on page If you are connecting within a private network such as a LAN, enter the network address of the host computer itself in the VNC Server dropdown.
Note the computer may not have a host name. Note IPv6 may not be enabled. If you do not know the network address of the host computer, start with Connecting within a private network on page If you are connecting over the Internet, and the host computer is protected by a router, then enter the network address of the router in the VNC Server dropdown instead.
If you do not know the network address of the router, see Connecting over the Internet on page VNC User Guide 21 Chapter 2: Getting Connected In the following example, the host computer is identified by an IPv4 network address: Typically, a host computer needs no further identification. This is because, by default, VNC Server listens for network communications on a registered port, Carry on from Step 4: Request an encrypted connection on page There may be circumstances, however, when VNC Server is listening on a different port.
If, when you try to connect, you see an error message similar to the following: Connection refused then you probably need to qualify the network address with a port number. For more information, see Qualifying a network address with a port number on page Step 4: Request an encrypted connection You can request that the connection be encrypted.
Encryption ensures that data exchanged between the two computers while the connection is in progress cannot be intercepted by third parties. Note that VNC Server determines whether or not connections are actually encrypted requesting encryption is not a guarantee. Note: For more information on encryption, and security in general, see Chapter 7 Making Connections , Secure on page You can request that this be enhanced to ultra-secure bit AES.
