LDAP Directory Database ldif

A record (also known as entry) in an LDAP database begins with a name, known as a distinguishing name, followed by a set of attributes and their values. The distinguishing name uniquely identifies the record. For example, a name could be a username and the attribute would be the user's e-mail address, the address being the attribute's value. Allowable attributes are determined by schemas defined in the etc ldap schema directory. This directory will hold various schema definition files, each...

KDE Directories and Files

When KDE is installed on your system, its system-wide application, configuration, and support files may be installed in the same system directories as other GUIs and user applications. On Ubuntu, KDE is installed in the standard system directories with some variations, such as usr bin for KDE program files usr lib kde3, which holds KDE libraries and usr include kde, which contains KDE header files used in application development. The directories located in the share directory contain files used...

Running Windows Software on Linux Wine

Wine is a Windows compatibility layer that allows you to run many Windows applications natively on Linux. Though you could run the Windows OS on Wine, the actual Windows OS is not required. Windows applications will run as if they were Linux applications, able to access the entire Linux file system and use Linux-connected devices. Applications that are heavily driver-dependent, such as graphics-intensive games, may not run. Others that do not rely on any specialized drivers may run very well,...

Motherboard RAID Support dmraid

With kernel 2.6, hardware RAID devices are supported with the Device-Mapper Software RAID support tool (dmraid), which currently supports a wide range of motherboard RAID devices. Keep in mind that many hardware RAID devices are, in effect, really software RAID (fakeraid). Though you configure them in the motherboard BIOS, the drivers operate as software, like any other drivers. In this respect, they could be considered less flexible than a Linux software RAID solution, and they could also...
