history

Project history and usage

UDPTunnel is a small Unix networking utility for carrying UDP packets over a TCP connection. Its own documentation describes the original motivation as letting multimedia conferences traverse firewalls that allowed only outgoing TCP.

Project history

Jonathan Lennox released UDPTunnel 1.0 in 1999 and version 1.1 in 2001. The 1.1 release was a relicensing and documentation update with no code changes, which helps explain why the package remains a compact, stable command-line tool rather than an actively evolving service.

Adoption history

The official page documents portability to POSIX socket platforms and notes testing on Solaris, Linux, and FreeBSD. Its package-manager presence is mostly as a small compatibility tool for users who need the exact UDP-over-TCP behavior rather than a broader VPN or proxy stack.

How it is used

UDPTunnel runs in client or server mode and relays UDP after establishing a TCP connection. The documentation also calls out RTP mode for paired RTP/RTCP multimedia traffic and explains that multicast addresses can be tunneled with an explicit TTL.

Why package nerds care

For package nerds, UDPTunnel is the sort of tiny historical network utility that survives because it does one old Internet job plainly: build with autoconf, install one binary, and tunnel UDP-like conference traffic through restrictive TCP-only paths.

Timeline

  • 1999-05-19: UDPTunnel 1.0 initial release.
  • 2001-09-06: UDPTunnel 1.1 re-released under a BSD-style license with documentation updates and no code changes.

Related projects

  • The documentation frames UDPTunnel around RTP-style multimedia traffic and notes incorporated code by Henning Schulzrinne.
