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. ### 项目历史 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. ### 采用历史 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. ### 使用方式 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. ### 为什么软件包爱好者会关心 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. ### 时间线 - 1996: UCSPI specification copyrighted by D. J. Bernstein. - 2000: ucspi-tcp 0.88 tarball published according to official HTTP metadata. - 2002: rblsmtpd documentation records then-current public RBL source status updates. - Current packaging: source_facts lists Homebrew, Debian, Ubuntu, MacPorts, Nix, and other package-manager entries. ### Related projects - The official rblsmtpd page points to tcpserver and tcprules as companion programs within the suite. - The documentation also points to rbldns from djbdns for running RBL or anti-RBL sources. ### 来源 -
