Glossary

This chapter provides definitions for Device Server terms.

BOOTP (BOOTstrap An Internet protocol that enables a diskless workstation to discover its own IP address, the IP

Protocol)address of a BOOTP server on the network, and a file to be loaded into memory to boot the machine. This enables the workstation to boot without requiring a hard or floppy disk drive.

Community (SNMP)

An SNMP community is the group that devices and management stations running SNMP belong

 

to. It helps define where information is sent.

DHCP (Dynamic Host

A TCP/IP protocol that provides static and dynamic address allocation and management.

Configuration

 

Protocol)

 

Direct Connection

Connections that bypass the Device Server enabling the user to log straight into a specific host.

 

A direct connection is recommended where a user logging in to the Device Server is not

 

required.

Ethernet

A high-speed (10Mbps,100Mbps) cable technology that connects devices to a LAN, using one

 

or more sets of communication protocols.

Local Authentication

Uses the user ID and password stored within the Device Server User database.

Modem Initialization

A series of commands sent to the modem by a communications program at start up. These

String

commands tell a modem how to set itself up in order to communicate easily with another

 

modem.

MOTD

Message of the day. This is defined by a file whose contents display when users log into the

 

Device Server.

Multicast

The broadcasting of messages to a specified group of workstations on a LAN, WAN, or internet.

NAK (Negative

A communication control character sent by the receiving destination indicating that the last

Acknowledgment)

message was not received correctly.

Reverse Connection

Connections that originate from a host that go directly to a serial device through the Device

 

Server.

Silent Connection

Silent connections are the same as direct connections except that they are permanently

 

established. The host login prompt is displayed on the screen. Logging out redisplays this

 

prompt. Silent connections, unlike direct connections, however, make permanent use of pseudo

 

tty resources and therefore consume host resources even when not in use.

SNMP (Simple

A protocol for managing network devices.

Network Management

 

Protocol)

 

Subnet/Prefix Bits

Identifies the device’s IP address, which portion constitutes the network address and which

 

portion constitutes the host address.
