aperçu
Tools for building TCP client-server applications
historique
ucspi-tcp is Daniel J. Bernstein's Unix Client-Server Program Interface implementation for TCP. It provides small command-line tools such as tcpserver and tcpclient for building TCP services and clients around ordinary Unix programs.
The UCSPI specification is dated 1996 and defines a command-line interface for client-server communication tools. ucspi-tcp applies that model to TCP, with clients and servers setting descriptors and environment variables before executing an application.
The official install page identifies ucspi-tcp 0.88 as the latest published package, and the official tarball has a March 18, 2000 last-modified date. The project is distributed from Bernstein's cr.yp.to site rather than through a public source-control repository.
ucspi-tcp became part of the classic djb software ecosystem, especially alongside daemontools-style service supervision and qmail-era mail setups. The input package metadata shows that, despite its age and tarball distribution model, it remains packaged in Homebrew, Debian, Ubuntu, MacPorts, Nix, and other Unix package collections.
Package users most often encounter tcpserver, tcpclient, tcprules, tcprulescheck, recordio, rblsmtpd, and helper tools. The official docs describe tcpserver as a way to accept TCP connections and run another program, while rblsmtpd is documented as an SMTP wrapper that blocks mail from listed sites when used under tcpserver.
For package nerds, ucspi-tcp is historically significant because it is a compact Unix networking toolkit from the pre-systemd, pre-framework era. It represents a style where small binaries, environment variables, file-descriptor conventions, and package-manager preservation keep old but sharp infrastructure tools available.
