In ZENworks Server Management, a utility in the Traffic Analysis Agent that enables or disables network monitoring by the selected network adapters and provides a source of detailed troubleshooting information.

Login Client ModuleA client-side component of an LSM. The LCM and LSM transmit login credentials using the Multiple Authentication Framework Functions.

logical channel numberA unique number given to each virtual circuit for a call. An LCN is attached to each packet in the call and differentiates the packets from packets generated by other users for other calls.

Link Control ProtocolA packet that provides procedures for establishing, configuring, testing, and terminating the operation of PPP data-link connections. LCP also automates the configuration and establishment of serial links for bridges and routers over wide area networks (WANs), and controls the header compression and link quality on dial-up PPP links.

Lightweight Directory Access ProtocolAn X.500-related Open Systems Interconnection (OSI) protocol that clients can use to read and write Directory information. LDAP is used to publish Directory information such as telephone numbers and e-mail addresses. The Directory features available to LDAP clients are dependent upon the features built into the LDAP server and the LDAP client; some clients have the ability to read and write data; others can only read Directory data.Web browsers and e-mail programs can query an LDAP-compliant directory (for example, Novell eDirectory).LDAP allows a client to search through a large database of addresses, phone numbers, and people stored on a server.

LDAP Directory Interchange FormatThe LDIF format is used to convey directory information (content records) or a description of a set of changes made to directory entries (change records). An LDIF file consists of a series of records separated by line separators.Records can be Change Records or Content Records. Content Records are usually the result from an LDAP query. They have a basic format of name-value pairs (usually "attribute name":"some value" - such as CN: David). Change Records contain a set of commands for a particular entry (such as add, delete, or modify). They are used when you want to modify entries within your directory.

A packet generated by a NetWare Link Services Protocol (NLSP) router that lists the router's neighbors and attached IPX networks.

A routing algorithm that controls the way each router broadcasts information about the state of its links (network attachments) to all nodes in the internetwork. This approach reduces routing loops and network traffic but has greater memory requirements than the distance vector algorithm.NetWare Link Services Protocol (NLSP), Open Shortest Path First (OSPF), and Intermediate System-to-Intermediate System (IS-IS) are examples of link state protocols.

A router that uses NLSP (NetWare Link State Protocol) to distribute its own link states to all other routers on the network and to update its database with link state information received from other routers.

To load a program during a computer or operating system startup process without any user intervention.Generally, this is done by adding a command to a startup file such as config.sys, startup.ncf, or autoexec.bat. Sometimes it is done simply by setting certain parameters in a program; for example, if a program that otherwise would load automatically required a password, setting the password would allow the program to load without user intervention.

One of the five types of container objects that can be created and added to the NDS tree. The other four are Country (C), Licensed Product (LP), Organization (O), and Organizational Unit (OU). Locality designates the location of this portion of the network. For example, if a Country object such as US exists, a Locality object, EAST, can be added for the East coast under US. The object is placed below the Country object, Organization object, or Organizational Unit object.

When you deploy your finished application, you can secure access to administrative functions in your application by changing the Locksmith to a known user in your directory realm.

One of the three types of files produced by each backup session. The other two are Data file and Error file. Log files are placed in a directory on the host server and accessed through the SBACKUP "Main Menu" screen. The log files are labeled with the same description given the session. Both log and error files contain information such as the session's date, time, and media identification, but the error file also contains a list of any errors that occurred during the backup session, such as files that were not backed up.
