history
Project history and usage
stone is a small TCP/IP packet repeater that works at the application layer. 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.
