Glossary
This chapter provides definitions for IOLAN 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 IOLAN enabling the user to log straight into a specific host. A |
| direct connection is recommended where a user logging in to the IOLAN is not required. |
Ethernet | A |
| or more sets of communication protocols. |
Local Authentication | Uses the user ID and password stored within the IOLAN 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 |
| IOLAN. |
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 IOLAN. |
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 devices IP address, which portion constitutes the network address and which |
| portion constitutes the host address. |
