The package exposes Geph's proxy, VPN, synchronization, binder, and diagnostic operations as a Rust command-line program. ### Project history The geph4-client repository was opened in 2020 as the command-line client for the fourth-generation Geph system. Its README describes a design built around exit servers, bridge servers, the sosistab2 transport, and client-side tunneling for proxy and VPN traffic. ### Adoption history Geph4 Client sits in a small but specialized ecosystem of Geph components, including the GUI client, bridge infrastructure, the sosistab2 transport, and binder services. Its significance comes from packaging censorship-circumvention behavior in a scriptable CLI rather than only in a graphical application. ### How it is used Practitioners run `geph4-client connect` with user credentials and an exit server to create local SOCKS5 and HTTP proxies, and may enable VPN mode on supported platforms. Other subcommands synchronize account and exit-server data, proxy binder API calls for the GUI, or export a debug SQLite database. ### Why package nerds care For package-manager users, geph4-client is useful because it installs the Rust CLI entry point without a manual Cargo build. That makes it easier to script Geph connections, wire local applications through localhost proxy ports, or test Geph behavior outside the GUI. ### Timeline - 2020: The geph4-client repository was opened on GitHub. - 2020s: The README documents bridge-backed exit-server connections, SOCKS5 and HTTP local proxies, VPN modes, and GUI support commands. ### Related projects - gephgui, bridge-phalanx, sosistab2, Mel ### Sources - - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** geph4 - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Related links - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Language runtime packages](https://www.automicvault.com/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [pkgconf](https://www.automicvault.com/pkg/brew/pkgconf/) - Build dependency declared by Homebrew. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [obfs4proxy](https://www.automicvault.com/pkg/brew/obfs4proxy/) - Shares av.db curated category or tags: censorship-circumvention, cli, networking, privacy, proxy. - [sing-box](https://www.automicvault.com/pkg/brew/sing-box/) - Shares av.db curated category or tags: cli, networking, proxy, vpn. - [xray](https://www.automicvault.com/pkg/brew/xray/) - Shares av.db curated category or tags: cli, networking, privacy, proxy. - [brook](https://www.automicvault.com/pkg/brew/brook/) - Shares av.db curated category or tags: cli, networking, proxy. - [connect](https://www.automicvault.com/pkg/brew/connect/) - Shares av.db curated category or tags: cli, networking, proxy. - [dante](https://www.automicvault.com/pkg/brew/dante/) - Shares av.db curated category or tags: cli, networking, proxy. - [ghostunnel](https://www.automicvault.com/pkg/brew/ghostunnel/) - Shares av.db curated category or tags: cli, networking, proxy. - [gost](https://www.automicvault.com/pkg/brew/gost/) - Shares av.db curated category or tags: cli, networking, proxy. - [hysteria](https://www.automicvault.com/pkg/brew/hysteria/) - Local package facts share a topical domain.
