Glossary¶

A¶

ABI¶

ABI stands for Application Binary Interface. An ABI is an interface that defines how two modules interact with each other at the machine code level. Most often, these modules are applications using external libraries. An ABI defines a low-level and hardware-dependent interface compared to an an Application Programming Interface (API), which is considered high-level and hardware-independent.

See ABI for more details.

DMAR¶: Direct Memory Access Remapping: It is a technology used to control and secure Direct Memory Access (DMA) operations and ensures that devices can only access memory regions they are authorized to, helping to prevent unauthorized access, memory corruption, or security vulnerabilities. It is often used in virtualized environments to isolate devices between virtual machines (VMs) and the host system.
dmesg¶: A command in Linux systems that displays system logs related to hardware, drivers, and kernel events, such as system startup, device detection, and errors. It is commonly used for troubleshooting hardware issues and system diagnostics.

The replication is transparent to other applications on the host systems. Any block device hard disks, partitions, RAID devices, logical volumes, etc can be mirrored.

F¶

failover¶

In a Storage Area Network (SAN) environment, this occurs when data flows into an alternative I/O path because a cable, switch, or controller in the current path failed. It is a common feature in high availability environments and is handled (usually automatically) by multipathing software.

fallbacks¶

This is a manual or automatic switch to an alternative method, when the primary option fails or is less preferred.

FastCGI¶

Fast Common Gateway Interface (FastCGI) is an extension of the CGI protocol that starts a persistent FastCGI application process, allowing it to handle multiple requests instead of starting a new process for each request like a traditional CGI does.

FC¶

Fiber Channel (FC) is a storage networking protocol used for low-latency communication between a storage device and a node in a Storage Area Network (SAN).

FHS¶

Filesystem Hierarchy Standard (FHS) is a standard that defines the directory structure and contents in Linux and Unix-like operating systems.

FileSet¶

A FileSet defines a group of directories that will be included when performing a backup job using Bacula.

Related topic(s): Storage

filesystem¶

A filesystem defines how data is organized, stored, and accessed on a storage device.

Related topic(s): Storage

Fluentd¶

Fluentd is a data collection platform that gathers events from a container for later analysis on other platforms.

Related topic(s): Observability, and Containers.

FQDN¶

A Fully Qualified Domain Name (FQDN) represents a complete name that specifies the exact location of a host within the DNS hierarchy.

Related topic(s): Networking, Web services, Security, Active directory integration, and OpenLDAP.

FreeIPA¶

Free Identity, Policy, and Audit (FreeIPA) is an open-source security solution for Linux/Unix-like systems that stores user identities in an LDAP directory, manages a CA, and enables authentication, policy enforcement, and auditing through integrations with SSSD and Kerberos.

Related topic(s): Security, and OpenLDAP.

freenode¶

Freenode is an open-source Internet Relay Chat (IRC) platform used by open-source communities for real-time discussions.

frontend¶

A frontend is a user-friendly interface for managing a complex system.

In firewall management, a frontend like ufw simplifies configuring iptables.
In QEMU/KVM graphics, a frontend is the virtual graphic adapter presented to the guest OS, allowing it to process and store graphical output in memory. The guest OS treats it like a GPU, while the host determines how to display the output using the backend.
In LDAP, the frontend is a unique database that defines global default settings, such as who the admin user is, who can access database entries, or the limit on the number of search results. These settings apply to all LDAP databases inside slapd, unless overridden.

Related topic(s): Virtualization and containers, Security, and OpenLDAP.

fsck¶

File System Check (fsck) is a Linux/Unix-like system utility tool that checks for, and repairs, any filesystem errors.

Related topic(s): Storage

FULLTEXT¶

FULLTEXT is an index type that allows for fast indexing and searching large quantities of text. It takes a sentence, splits it into words, and links them to row IDs. When a search query for a word is made, MySQL quickly looks up the row the word appear in, and retrieves all matching row IDs, rather than scanning the entire table. It can also find similar words using natural language processing.

See Full-Text Search Functions for more details.

G¶

gcplogs¶

A logging driver that allows logs to be forwarded from a Docker container running in Google Cloud to the Google Cloud Logging service.

Related topic(s): Containers, and Observability.

gcrypt¶

Related topic(s): Cryptographic libraries

GDB¶

Related topic(s): Active Directory integration, Containers, Kerberos, Multipath, OpenLDAP, Samba, Security, SSSD.

gitolite¶

Gitolite is a tool installed on a central server for managing git repositories and controlling access to them, all via the command line. The central server becomes a git server.

Related topic(s): Backups and version control

GKE¶

Google Kubernetes Engine (GKE) is a managed Kubernetes service provided by Google cloud.

GL¶

GL (Graphics Library) is an API for interacting with a graphics card, enabling it to perform better rendering.

H¶

HA¶

High Availability (HA) is the process of ensuring that a system is always up. To achieve this, a redundant system is setup that either takes over when the main system is down or runs alongside the main system to load balance the workload.

Related topic(s): High availability, and OpenLDAP.

HBAs¶

Host Bus Adapters (HBAs) are interface cards that connect a server to a storage device.

Related topic(S): Device mapper multipathing and Server installation

HMAC¶

A Hash-based Message Authentication Code (HMAC) is a type of Message Authentication Code (MAC). While a general MAC may use various techniques during combination, HMAC follows a structured way. When a message and its HMAC are sent, the receiver verifies the integrity by computing the HMAC again - if the message is altered, the value will differ.

Related topic(S): High availability, Kerberos, Cryptography, and Security.
