It listens on a local TCP port and forwards received data to a remote host, making it a simple utility for redirecting TCP-based protocols. ### Project history The official homepage and ChangeLog date the first public release to 2000-08-15. Later entries show the portability-driven shape of the project: HP-UX and SunOS support in 2000, Windows support in 2004, renewed cleanup and fork-based concurrency in 2010, Cygwin fork support in 2013, and Mac OS X support in version 0.8. ### Adoption history The supplied package metadata shows Homebrew packaging, and the README explicitly thanks a Homebrew pull request for Mac OS X installation instructions. The official homepage also provided source and Windows binary downloads, so the tool was distributed both as a small upstream tarball and as a package-manager formula. ### How it is used The official documentation describes redirecting TCP-based protocols such as HTTP, IRC, NNTP, SSH, and SMTP. The CLI exposes local and remote port settings, remote host, bind and client address controls, buffer size, forked concurrency, logging, and stay-alive behavior. ### Why package nerds care tcptunnel is the kind of package that remains useful because it is minimal: install it, bind a local port, and forward bytes. It matters in the package-nerd niche as a compact alternative when a full proxy, SSH tunnel setup, or larger networking toolkit would be unnecessary. ### Timeline - 2000-08-15: tcptunnel 0.1 first public release. - 2000-09-14: 0.1g added HP-UX and SunOS support. - 2004-12-28: 0.2 added Windows support. - 2010-09-21: Added fork-based concurrent client handling. - 2013-10-27: 0.8 added Mac OS X support and a buffer-size option. ### Related projects - The official page frames tcptunnel around TCP-based protocols including HTTP, IRC, NNTP, SSH, and SMTP; Cygwin and MinGW appear as Windows build environments in the README. ### Sources - - - - input source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** tcptunnel - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Homebrew utility packages](https://www.automicvault.com/pkg/brew-utility-packages/) - Matched Homebrew package provider. - [udptunnel](https://www.automicvault.com/pkg/brew/udptunnel/) - Shares av.db curated category or tags: cli, networking, tcp, tunneling. - [bore-cli](https://www.automicvault.com/pkg/brew/bore-cli/) - Shares av.db curated category or tags: cli, networking, port-forwarding, tunneling. - [dns2tcp](https://www.automicvault.com/pkg/brew/dns2tcp/) - Shares av.db curated category or tags: cli, networking, tcp, tunneling. - [jprq](https://www.automicvault.com/pkg/brew/jprq/) - Shares av.db curated category or tags: cli, networking, tcp, tunneling. - [ptunnel](https://www.automicvault.com/pkg/brew/ptunnel/) - Shares av.db curated category or tags: cli, networking, tunneling. - [autossh](https://www.automicvault.com/pkg/brew/autossh/) - Shares av.db curated category or tags: cli, networking, tunneling. - [boring](https://www.automicvault.com/pkg/brew/boring/) - Shares av.db curated category or tags: cli, networking, port-forwarding, tunneling. - [localtunnel](https://www.automicvault.com/pkg/brew/localtunnel/) - Shares av.db curated category or tags: cli, networking, tunneling. - [redir](https://www.automicvault.com/pkg/brew/redir/) - Local package facts share a topical domain.
