It keeps DNS host records synchronized with changing public IP addresses, especially for home servers, routers, gateways, and redundant Internet connections. ### Project history The Troglobit GitHub repository was created in 2010, while older provider documentation identifies inadyn as a C-based DDNS client written by inarcis. Troglobit's line modernized the project around HTTPS support, a libConfuse-based configuration format, provider plugins, systemd integration, and many service-provider examples. A 2014 Troglobit release note described the project as reignited and pointed toward the 2.0 configuration format. The repository's GitHub releases show the 1.99.x bridge releases in 2014 and 2015, then a long 2.x line of DDNS provider additions and fixes. ### Adoption history Inadyn's adoption is tied to appliances and distribution packaging. The project README and Troglobit project page both say it is common in GNU/Linux distributions and off-the-shelf routers and Internet gateways, which matches the batch metadata listing apk, Homebrew, Debian, Fedora, MacPorts, Nix, and Ubuntu packages. ### How it is used Users place provider credentials, hostnames, and update policy in inadyn.conf. The daemon periodically or on demand checks the public address and updates one or more DDNS records through providers such as FreeDNS, Cloudflare-style APIs, and other supported services. ### Why package nerds care For package people, inadyn is the archetypal tiny network daemon: one C program, one config file, one service unit, and decades of DDNS-provider churn encoded as package updates. It matters because it is often the glue that makes a dynamic residential or small-office connection reachable by a stable hostname. ### Timeline - 2010: Troglobit GitHub repository created. - 2014: v1.99.7 and v1.99.8 release notes described project revival, provider plugin work, HTTPS support, and the path toward 2.0. - 2015: 1.99.x bridge releases continued on GitHub. - 2020: Troglobit project page documented the common /etc/inadyn.conf layout and systemd service usage. - 2025: GitHub repository archived after the 2.12.0 release line. ### Related projects - inadyn-mt and inadyn-advanced are related DDNS-client forks documented by SourceForge and package metadata. - ddclient, router firmware DDNS clients, systemd service units, and provider-specific DDNS APIs occupy the same operational space. ### Sources - - - - - - - - input.json source_facts.package-manager ## Security Notes No matching local secret-handling manifest was found for inadyn. Nucleus package metadata is still published here so future coverage has a stable package URL. ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials. Automic Vault can use them as review targets for secret scanning, migration, and command approval. ## Configuration files - Unix: /etc/inadyn.conf ## Credential files - Unix: /etc/inadyn.conf ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** inadyn - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** yes - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Debian apt - inadyn - 2.11.0-1+b1: normalized package name match | Debian stable package indexes: inadyn from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | simple and small dynamic DNS client with HTTPS support | https://github.com/troglobit/inadyn - Nix - inadyn: normalized package name match | nixpkgs package indexes: pkgs/by-name/in/inadyn/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - inadyn - 2.11.0-1build2: normalized package name match | Ubuntu 24.04 LTS package indexes: inadyn from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | simple and small dynamic DNS client with HTTPS support | https://github.com/troglobit/inadyn - apk - inadyn - 2.13.0-r0: normalized package name match | Alpine Linux edge package indexes: inadyn from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Dynamic DNS client with TLS support | https://troglobit.com/projects/inadyn - apk - inadyn-doc - 2.13.0-r0: normalized package name match | Alpine Linux edge package indexes: inadyn-doc from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Dynamic DNS client with TLS support (documentation) | https://troglobit.com/projects/inadyn - apk - inadyn-openrc - 2.13.0-r0: normalized package name match | Alpine Linux edge package indexes: inadyn-openrc from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | Dynamic DNS client with TLS support (OpenRC init scripts) | https://troglobit.com/projects/inadyn - dnf - inadyn-mt - 2.28.10-26.fc44: normalized package name match | Fedora Rawhide package metadata: inadyn-mt from https://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/Everything/x86_64/os/repodata/e5ca8ce900cd68f5419e1c39ae517343100b306336cbaeb70a3c153121d95094-primary.xml.zst | Dynamic DNS Client | http://inadyn-mt.sourceforge.net - MacPorts - inadyn: normalized package name match | MacPorts ports tree: net/inadyn/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Security and crypto packages](https://www.automicvault.com/pkg/security-crypto-tools/) - Matched security, identity, cryptography, password, signing, or certificate metadata. - [Homebrew utility packages](https://www.automicvault.com/pkg/brew-utility-packages/) - Matched Homebrew package provider. - [openssl@4](https://www.automicvault.com/pkg/brew/openssl-4/) - Runtime dependency declared by Homebrew. - [pkgconf](https://www.automicvault.com/pkg/brew/pkgconf/) - Build dependency declared by Homebrew. - [ddns-go](https://www.automicvault.com/pkg/brew/ddns-go/) - Shares av.db curated category or tags: cli, dns, dynamic-dns, ipv4, ipv6. - [ddclient](https://www.automicvault.com/pkg/brew/ddclient/) - Shares av.db curated category or tags: cli, dns, dynamic-dns, networking. - [adns](https://www.automicvault.com/pkg/brew/adns/) - Shares av.db curated category or tags: cli, dns, networking. - [aliddns](https://www.automicvault.com/pkg/brew/aliddns/) - Shares av.db curated category or tags: cli, dns, networking. - [bind](https://www.automicvault.com/pkg/brew/bind/) - Shares av.db curated category or tags: cli, dns, networking. - [c-ares](https://www.automicvault.com/pkg/brew/c-ares/) - Shares av.db curated category or tags: cli, dns, networking. - [cdncheck](https://www.automicvault.com/pkg/brew/cdncheck/) - Shares av.db curated category or tags: cli, dns, networking. - [checkdmarc](https://www.automicvault.com/pkg/brew/checkdmarc/) - Shares av.db curated category or tags: cli, dns, networking. - [icann-rdap](https://www.automicvault.com/pkg/brew/icann-rdap/) - Local metadata places this package in an adjacent workflow.
