minidjvu is a multipage DjVu encoder and single page encoder/decoder. It doesn't support colors or grayscales, just black and white.

ocrodjvu is a wrapper for OCR systems, that allows you to perform OCR on DjVu files.

DjView is a standalone viewer for DjVu files.

Its features include navigating documents, zooming and panning page images, producing and displaying thumbnails, displaying document outlines, searching documents for particular words in the hidden text layer, copying hidden text to the clipboard, saving pages and documents as bundled or indirect multi-page files, and printing page and documents.

The viewer can simultaneously display several pages using a side-by-side or a continuous layout.

This is a small tool to convert DjVu files to PDF files.

pdf2djvu creates DjVu files from PDF files. It is able to extract:

• graphics,

• text layer,

• hyperlinks,

• document outline (bookmarks),

• metadata (including XMP metadata).

DMD is the reference compiler for the D programming language.

d_demangle is a small utility that can be used to demangle D symbols. A shared library is also provided.

This package provides bindings to GTK+ for D.

d-tools provides two useful tools for the D language: rdmd, which runs D source files as scripts, and dustmite, which reduces D code to a minimal test case.

This package provides a DMD-like wrapper for the GNU D Compiler.

LDC is an LLVM compiler for the D programming language. It is based on the latest DMD compiler that was written in C and is used for bootstrapping more recent compilers written in D.

DUB is a package and build manager for applications and libraries written in the D programming language. It can automatically retrieve a project's dependencies and integrate them in the build process.

The design emphasis is on maximum simplicity for simple projects, while providing the opportunity to customize things when needed.

This package contains a small DNS daemon especially made to handle queries of DNSBL, a simple way to publish IP addresses and/or (domain) names which are somehow notable. Such lists are frequently used to refuse e-mail service to clients known to send unwanted (spam) messages.

rbldnsd is not a general-purpose nameserver. It answers to a limited variety of queries. This makes it extremely fast---greatly outperforming both BIND and djbdns---whilst using relatively little memory.

MaraDNS is a small and lightweight DNS server. MaraDNS consists of a UDP-only authoritative DNS server for hosting domains, and a UDP and TCP-capable recursive DNS server for finding domains on the internet.

SmartDNS is a DNS server that accepts DNS query requests from local clients, obtains DNS query results from multiple upstream DNS servers, and returns the fastest access results to clients.

Knot DNS is an authoritative name server for the Domain Name System (DNS), designed to meet the needs of root and top-level domain (TLD) name servers. It is implemented as a threaded daemon and uses a number of programming techniques to improve speed. For example, the responder is completely lock-free, resulting in a very high response rate. Other features include automatic DNS Security Extensions (DNSSEC) signing, dynamic record synthesis, and on-the-fly re-configuration.

YADIFA is an authoritative name server for the Domain Name System (DNS). It aims for both higher performance and a smaller memory footprint than other implementations, while remaining fully RFC-compliant. YADIFA supports dynamic record updates and the Domain Name System Security Extensions (DNSSEC).

openresolv is an implementation of resolvconf, the middleman between the network configuration services and /etc/resolv.conf. resolvconf itself is just a script that stores, removes and lists a full resolv.conf generated for the interface. It then calls all the helper scripts it knows about so it can configure the real /etc/resolv.conf and optionally any local nameservers other than libc.

This command line tool to update Cloudfare DNS records is useful for tasks such as updating dynamic DNS records or updating DNS records for the ACME DNS-01 protocol.

hnsd is a host name resolver for the Handshake Naming System (HNS) peer-to-peer network.

NSD, short for Name Server Daemon, is an authoritative name server for the Domain Name System (DNS). It aims to be a fast and RFC-compliant nameserver.

NSD uses zone information compiled via zonec into a binary database file (nsd.db). This allows fast startup of the name service daemon and allows syntax-structural errors in zone files to be flagged at compile time, before being made available to NSD service itself. However, most traditional BIND-style zone files can be directly imported into NSD without modification.

The collection of programs and processes that make up NSD are designed so that the daemon itself runs as a non-privileged user and can be easily configured to run in a chroot jail, thus making any security flaws in NSD less likely to result in system-wide compromise.

DNSSEC-Trigger enables your computer to use DNSSEC protection for the DNS traffic. It relies on the Unbound DNS resolver running locally on your system, which performs DNSSEC validation. It reconfigures Unbound in such a way that it will signal it to to use the DHCP obtained forwarders if possible, fallback to doing its own AUTH queries if that fails, and if that fails it will prompt the user with the option to go with insecure DNS only.

BIND implements the DNS protocols for the Internet. It is both a reference implementation of those protocols and production-grade software, suitable for use in high-volume and high-reliability applications.

The name stands for "Berkeley Internet Name Domain" because the software originated in the early 1980s at the University of California at Berkeley.

The utils output of this package contains the following command line utilities related to DNS name servers:

delv

DNS lookup and validation utility

dig

DNS lookup utility

host

DNS lookup utility

nslookup

Internet name servers interactive query utility

nsupdate

Dynamic DNS update utility

Knot Resolver is a caching full resolver implementation written in C and LuaJIT, both a resolver library and a daemon.
