Using the Telnet Viewer

327
The DSView 3 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 3 software clients may use the DSView 3 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 3 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 3 software.
Requirements
The Telnet Viewer is actually an applet that runs within the Java 1.5.0_02 plug-in (JRE). The
Telnet Viewer may also work with other Java versions. The DSView 3 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 23 for information
about user interaction with the JRE installer.
