# Support for KVM Redirection

Intel AMT 6.0 and higher includes support for third-party applications to operate Intel AMT systems using remote Keyboard, Video and Mouse (KVM) Redirection.

KVM Redirection lets you remotely operate a system as if you are physically located at the remote system. KVM Redirection uses Virtual Network Computing (VNC) to “share” the graphical output of the remote system. The results of keyboard and mouse commands transmitted to the remote system over the network are displayed on the screen of the local system.

VNC includes two main components:

- VNC Server – An application located on the remote managed system that permits the VNC Client to connect to and operate the system. From Intel AMT 6.0, a VNC Server component is embedded in the Intel AMT device.
- VNC Client – An application, usually located on a management server, used to connect to and operate the remote managed system.

To use KVM Redirection with Intel AMT requires that:

1. KVM is enabled in the Intel MEBX of the Intel AMT system. If disabled in the Intel MEBX, KVM cannot be enabled by Intel SCS during configuration (it must be done manually at the system).
2. The KVM Redirection interface is enabled in the Intel AMT device.
3. A VNC Client is installed on the computer that will control the Intel AMT systems.

VNC Clients

VNC Clients can connect to the VNC Server in the Intel AMT device using these ports:

- Redirection Ports (16994 and 16995) – These ports are available to VNC Clients that include support for Intel AMT authentication methods. To use these ports, the VNC Client user must be defined in the Intel AMT device (see Defining the Access Control List (ACL)). Port 16995 also uses Transport Layer Security.
- Default Port (5900) – VNC Clients that do not include support for Intel AMT can use this port. This is a less secure option. To use this port:
  - The VNC Client user must supply the Remote Frame Buffer (RFB) protocol password defined in the Intel AMT device. To define the RFB password, see Defining System Settings.
  - Port 5900 must be open on the Intel AMT device. Intel SCS does not open this port.

Note:
The VNC Client must use version 3.8 or 4.0 of the Remote Frame Buffer (RFB) protocol.
