Telnet
A terminal emulation program for TCP/IP networks such as the Internet that is commonly used to
remotely control web servers. The Telnet program runs on your PC and connects your PC to a
server on the network. Commands may then be entered through the Telnet program and will be
executed as if being entered directly on the server console, which enables you to control the server
and communicate with other servers on the network. To start a Telnet session, you must log in to a
server by entering a valid username and password.
Telnet Session
A type of target device session in which the target device supports Telnet and the DSView Client
connects directly to the target device using Telnet. A generic appliance is used for Telnet sessions.
A DSR switch or CPS appliance is not used for Telnet sessions.
Telnet/SSH Applet
A software component that provides the user interface needed to display a remote target device
through Serial over IP sessions.
Tiered Switch
A cascade switch. See the definition of Cascade Switch.
Unit
A generic term that refers to either a target device or a managed appliance. For example, the Unit
List may contain both target devices and managed appliances.
User Datagram Protocol (UDP)
Abbreviated UDP, a connectionless protocol that runs on top of IP networks like TCP. Unlike TCP/
IP, UDP/IP provides very few error recovery services, offering instead a direct way to send and
receive datagrams over an IP network. UDP is primarily used for broadcasting messages over a
network.
Video Viewer
A software component that provides the user interface needed to display a remote target device
through KVM over IP sessions.
Virtual Private Network (VPN)
A means of implementing a private network on a public network such as the Internet. By
encrypting data and assigning addresses, the impression is given to networks at each end of the
VPN that they are connected by a private physical network instead of across a public network.
