2 DSView Installer/User Guide
A Video Viewer window allows you to control the keyboard, monitor and mouse functions of
individual target devices connected to a DSR switch in real time. You may also use predefined
global macros to perform actions within the Video Viewer window, or create new macros within
the window for the device. The Video Viewer window may be launched by clicking KVM Session
in a DSView 3.0 Explorer Unit Views window for any target device, or clicking KVM Session or
Exclusive KVM Session (none-shared) in the Unit Overview window for the target device.
Devices connected to a CPS appliance may be accessed using a Telnet/SSH applet window.
Secure authentication and communication
Secure Socket Layer (SSL) encryption may be used to encrypt data traveling within the DSView
system. DSView users may be authenticated using the DSView Server internal database, or using a
Lightweight Directory Assistance Protocol (LDAP), Active Directory
®
or Windows NT
®
domain
external authentication server.
Creating and managing user permissions
The DSView software provides centralized network access, control and security for managed
appliances. A DSView Administrator may add, remove, delete and modify managed appliances and
target devices, including assigning permissions and per-device contact information, which are
stored on the DSView Server. A DSView Administrator may also assign unique permissions which
allow individual DSView users or a group of DSView users access to units.
DSView users may be authenticated using the local DSView internal database or by an
external server.
Proxy server access
The DSView software also contains a proxy server feature that allows KVM and Serial Sessions to
be proxied through the DSView Server. When a session is initiated with a target device, the Video
Viewer communicates using the Avocent Proxy Protocol (APP) and the DSView Server makes a
direct connection to the appliance. See Hub DSView Server Properties on page 56 for information
on specifying a proxy server.
DSView System Components
The following components comprise a DSView system:
DSView software
The DSView software resides on the DSView Server (host computer) and provides a web gateway
and services for managing units (managed appliances and target devices) using a web browser. The
gateway allows for IP-based video, serial management, Telnet SSH applet or web browser sessions.
DSView users may connect to the DSView Server from DSView Clients and use the DSView 3.0
Explorer window to communicate with the system.
