Step 3: Identify VNC Server running on the host computer

You must uniquely identify VNC Server running on the host computer you want to control.

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. This address can take the following forms:

•  A host name for the host computer, for example johndoe. (Note the computer may not have a host name.)

•  An IP address for the host computer in IPv4 format, for example 192.168.0.133.

•  An IP address for the host computer in IPv6 format within square brackets, for example [2001:db8::1]. (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.

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.

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, 5900. Carry on from Step 4: Request an encrypted connection.

There may be circumstances, however, when VNC Server is listening on a different port. This can occur if the host computer is running UNIX/Linux, or if more than one instance of VNC Server is running on the host computer. If, when you try to connect, you see an error message similar to the following:

Connection refused (10061)

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.
