Using the Telnet Viewer

327

The DSView management software ships bundled with a built-in proprietary Telnet Viewer that

provides features unavailable in many other Telnet programs. These features include configurable

session properties tailored for each device, configurable user preferences for all sessions, a

scripting function for automatic device login, a macro function and a logging function.

About the Telnet Viewer

DSView software clients may use the DSView management software Telnet Viewer to access

CPS810 and 1610 appliances and their ports, CCM 850, 1650 and 4850 appliances and their

ports, or any generic appliance that supports Telnet Viewer connections.

NOTE: Throughout this chapter, the term “appliance” or “managed appliance” will be used to indicate a supported

CPS appliance, CCM appliance or generic appliance that supports Telnet Viewer connections.

When a session is established with a supported appliance, the Telnet client switches to SSH

(Secure Shell) mode and opens an SSH shell to/through the appliance. The SSH shell can use any

of the Telnet client’s terminal emulations. See Security Property on page 330.

The Telnet Viewer uses the credentials provided by the DSView software to establish a session

and will automatically accept the appliance server key. The username and password provided by

the users when they log in are authenticated by the authentication service configured in the

DSView software.

Requirements

The Telnet Viewer is actually an applet that runs within the Java plug-in (JRE). The Telnet

Viewer may also work with other Java versions. The DSView software client automatically

downloads and installs the JRE (Java Runtime Environment) the first time the Video Viewer or

the Telnet Viewer is launched. See Java Installation on page 22 for information about user

interaction with the JRE installer.
