Its packaging appeal is old-school and practical: install one binary, repeat TCP or UDP through a firewall, add SSL support, or bridge simple protocol gaps. ### Project history Hiroaki Sengoku's official page dates stone's copyright to 1995-2021 and publishes version 2.4. The same page describes stone as a repeater for TCP and UDP traffic from inside to outside a firewall or from outside to inside. ### Adoption history The official page emphasizes portability across Win32, Linux, FreeBSD, BSD/OS, SunOS, Solaris, HP-UX, and related Unix systems. The supplied package metadata shows modern packaging in Homebrew, Debian, Ubuntu, and Nix, which keeps this older networking utility reachable through current package managers. ### How it is used The examples show command-line invocations for telnet, DNS over UDP, NTP over UDP, HTTPS-style SSL wrapping, SSL telnet, and an HTTP proxy. The page also highlights OpenSSL support, POP-to-APOP conversion, IPv6 support, and the project's deliberately small C codebase. ### Why package nerds care stone is the kind of compact network tool package maintainers keep around because it solves firewall, proxy, protocol-conversion, and debugging problems without a framework. It represents a classic Unix packaging pattern: a small C utility with decades of practical compatibility. ### Timeline - 1995: Official page copyright begins for stone. - 2000: Official page references Nikkei Linux articles explaining stone. - 2019: Official page lists stone 2.4 as the official release. - 2021: Official page copyright range extends through 2021. ### Related projects - The official page links OpenSSL for encryption support and MD5/RFC 1321 material for POP-to-APOP conversion. Its CVS repository is linked from the official snapshot section. ### Sources - - - input.source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** stone - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Debian apt - stone - 2.4-1.2: normalized package name match | Debian stable package indexes: stone from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | TCP/IP packet repeater in the application layer - Nix - stone: normalized package name match | nixpkgs package indexes: pkgs/by-name/st/stone/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - stone - 2.4-1build3: normalized package name match | Ubuntu 24.04 LTS package indexes: stone from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | TCP/IP packet repeater in the application layer ## 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. - [proxytunnel](https://www.automicvault.com/pkg/brew/proxytunnel/) - Shares av.db curated category or tags: cli, networking, proxy, tcp. - [redir](https://www.automicvault.com/pkg/brew/redir/) - Shares av.db curated category or tags: cli, networking, proxy, tcp. - [rinetd](https://www.automicvault.com/pkg/brew/rinetd/) - Shares av.db curated category or tags: cli, networking, proxy, tcp. - [tproxy](https://www.automicvault.com/pkg/brew/tproxy/) - Shares av.db curated category or tags: cli, networking, proxy, tcp. - [brook](https://www.automicvault.com/pkg/brew/brook/) - Shares av.db curated category or tags: cli, networking, proxy. - [cntlm](https://www.automicvault.com/pkg/brew/cntlm/) - Shares av.db curated category or tags: cli, networking, proxy. - [connect](https://www.automicvault.com/pkg/brew/connect/) - Shares av.db curated category or tags: cli, networking, proxy. - [ctrld](https://www.automicvault.com/pkg/brew/ctrld/) - Shares av.db curated category or tags: cli, networking, proxy. ## Combined YAML source View the package source record on GitHub.
