Amanda Configuration

Configuration files are placed in etc amanda, and log and database files are in var lib amanda. These are created automatically when you install Amanda. You will need to create a directory to use as a holding disk where backups are kept before being written to the tape. This should be located on a file system with a large amount of available space, enough to hold the backup of your largest entire host. Within the etc amanda directory are subdirectories for the different kind of backups you want...

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...

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...
