项目历史

redir was originally created by Nigel Metheringham and Sam Creasey as a lightweight, 8-bit-clean TCP port redirector for Unix. It could operate under inetd or as a standalone daemon handling multiple connections.

Maintenance later moved to Joachim Wiberg under the troglobit organization on GitHub. The maintained code uses GNU Autotools and preserves optional support for traffic shaping, FTP redirection, Linux transparent proxy mode, TCP wrappers, and a subset of the older interface.

Version 3.0 changed the command-line syntax. The build-time --enable-compat option retains a limited subset of version 2 options for older deployments.

采用历史

redir has been packaged across Homebrew, Debian, Ubuntu, Fedora-family repositories, and Nix according to the supplied metadata. That breadth reflects its role as a small, conventional Unix networking utility.

The current project retains inetd integration while also supporting standalone daemon and foreground operation, allowing it to fit both traditional Unix service management and modern process supervisors.

使用方式

The modern syntax specifies source and destination endpoints, for example redir :80 127.0.0.1:8080. Options control binding, foreground or inetd mode, logging, timeouts, FTP handling, transparent proxying, and traffic shaping.

No application-specific configuration or credential file is required; persistent service definitions belong to the chosen supervisor, such as inetd.conf or a systemd unit.

为什么软件包爱好者会关心

redir is representative of the compact Unix networking tools that package collections preserve for decades: one executable, a manual page, conventional Autotools support, and compatibility with inetd-era service composition. It remains useful when a complete proxy suite would be unnecessary.

Its version 3 command-line transition is especially relevant to maintainers because compatibility with part of the version 2 syntax must be enabled at build time.

• uredir, linked by the official README, provides UDP port redirection.
• inetd and xinetd can supervise redir and add access control through TCP wrappers; modern deployments can instead run it in the foreground under systemd or another process monitor.
