LAN (local area network)

Multiple systems at a single geographical site connected together for the purpose of sharing and exchanging data and software.

LAN/WAN

Local area network/wide area network. See LAN and WAN.

Large file

A regular file whose size is greater than or equal to 2GB.

Large fileaware

A utility is called large fileaware if it can process large files in the same manner that it does small files. A large fileaware utility can handle large files as input and can generate large files as output. The newfs, mkfs, mount, umount, tunefs, labelit, and quota utilities are all large fileaware for UFSs.

Large filesafe

A utility is called large filesafe if it causes no data loss or corruption when it encounters a large file. A utility that is large filesafe cannot properly process a large file, so it returns an appropriate error. Some examples of utilities that are not large fileaware but are large filesafe include the vi editor and the mailx and lp commands.

LDAP (Lightweight Directory Access Protocol)

This is the latest name-lookup service (directory service) to be added to Solaris.

Live upgrade

Provides a method of upgrading while your Solaris system is still running. The original system configuration remains fully functional and unaffected by the upgrade. The upgrade creates a duplicate boot environment that is activated when the system is rebooted. If a failure occurs, you can revert to the original boot environment, thereby eliminating the downtime associated with the normal test and evaluation process.

Local printer

A printer that is physically connected to a system and is accessed from that system.

Locale

A geographic or political region or community that shares the same language, customs, or cultural conventions (English for the United States is en_US, and English for the United Kingdom is en_UK).

Logical device name

Symbolic links pointing to the physical device name stored in the /devices directory. A logical device's name is used to refer to a device when you are entering commands on the command line. All logical device names are stored in the /dev directory.

Logical volume

Allows file systems to span multiple disks and provide for improved I/O and reliability compared to the standard Solaris file system.

Logging

See journaling.

LPD (Line Printer Daemon)

A TCP/IP printer protocol that provides print spooling and network printing. Originally developed for Berkeley Unix (BSD Unix), LPD has become the de facto cross-platform printing protocol.

lpsched
