event control blockA structure that controls events related to the transmission and reception of IPX and SPX packets. ECBs also control the establishment and termination of SPX sessions.

A distributed, replicated naming service that maintains information about and provides access to a list of objects that represent network resources, such as network users, servers, printers, print queues, and applications. The directory is physically stored as a set of database files on a server. If the server hosts file system volumes, these files are on volume sys:. If no volumes are present, the directory is stored on the server's local disk. eDirectory tightly integrates Novell Security Services for e-commerce (PKI, cryptography, and authentication services), allowing developers to build applications that can be accessed and managed across the entire network through explicit policies.

In ZENworks Desktop Management, a Novell Application Launcher (NAL) macro that specifies information from an eDirectory object attribute.

A small, flexible framework for managing, maintaining, and monitoring eDirectory through the Internet, intranet, and extranets through wired and wireless devices. eMFrame leverages roles, which are defined in the directory, allowing organizations to present only the tasks applicable to a user.

Each object in the eDirectory tree has a name, which is determined by the value of the eDirectory schema attribute and which the object's base object class definition specifies. Currently, eDirectory has four name types that identify objects in the eDirectory tree:1. Relative Distinguished Name 2. Name Context 3. Fully Qualified Distinguished Name 4. Partially Qualified Distinguished Name For more information see this article.

A Directory tree that consists of see this article.">eDirectory objects such as multiple levels of organizational units, users, groups, and other network resources.

Exterior Gateway ProtocolA protocol that exchanges network access information between autonomous systems. EGP is part of the TCP/IP protocol suite.Routers within each autonomous system are chosen to use EGP to talk to the outside world, usually over the Internet. These EGP routers are called exterior routers.The exterior routers become EGP neighbors. The EGP neighbors exchange information about the networks that can be reached within the neighbors' respective autonomous systems.

A record of the system messages that have appeared on the server console. It is stored as a text file on the server and keeps growing until the network administrator clears it.The system messages in the log might be related to eDirectory synchronization, file migration, NetWare Loadable Module (NLM) execution, disk mirroring, or any other server operation.

A high-speed local area network hardware standard that consists of a cable technology and a series of communication protocols. Ethernet uses a bus topology (configuration). It is the primary communications circuitry used in many mainframe, PC, and UNIX networks.Ethernet is the most widely installed local area network technology. An Ethernet LAN typically uses coaxial cable or special grades of twisted pair wires. The most commonly installed Ethernet systems are called 10BASE-T and provide transmission speeds up to 10 Mbps. Devices are connected to the cable and compete for access using a Carrier Sense Multiple Access with Collision Detection (CSMA/CD) protocol.

An AppleTalk network on Ethernet. An EtherTalk network can be either nonextended (EtherTalk 1.0) or extended (EtherTalk 2.0).

Conference Europeenne des Postes et des Telecommunications (European Conference of Postal and Telecommunications Administration)The association of the European Post, Telephone, and Telegraph agencies (PTT) that recommends communication specifications to the International Telecommunication Union Telecommunication Standardization Sector (ITU-T). This governing body created the facility used to transport 30 voice channels at 64 Kbs (for a total of 2.048 Mbps); also known as "E1."

The maximum number of uncommitted data bits that the network attempts to deliver over a measured time interval.

A specific type of link unit (commands and responses) used to carry node and link characteristics between adjacent nodes.XIDs are exchanged between link stations before activation to negotiate acceptable characteristics. XIDs are also exchanged during activation to adjust for changes in these characteristics.

A file system attribute that prevents a file from being copied. Only users with the Supervisor right to the file can set this attribute. Once set, this attribute can't be removed, so users should have a backup copy of the file.

In ZENworks Handheld Management, refers to a storage device that plugs into a Palm OS device's expansion slot to store software applications, pictures, and audio files. Also called secure digital (SD) cards or memory sticks.

Any of the advanced parameters used to provide more specific control on packet-level operations (such as NetWare Link/X.25 Packet layer) and frame-level operations.

An AppleTalk network on high-speed media, such as Ethernet, token ring, or FDDI. An extended network is capable of supporting the Phase 2 addressing extensions of a network range and zones list.

Similar to named data streams; however, they use the NetWare extended attribute naming semantics. Extended attributes also have their own object type, because they contain a unique piece of metadata that is not contained in the data stream object. This metadata is a user-defined 32-bit value that is stored with each extended attribute and that is opaque in meaning to Novell Storage Services (NSS).
