Knock is a minimal, native port-knocking client for iOS. Open ports in your firewall - SSH, VPN, admin panels - by sending a saved sequence from your iPhone. Save named configurations with a host, a list of ports, a delay, and a timeout. Each port can be independently TCP or UDP. Run the sequence with a single tap and watch each knock's result stream in live. FEATURES • Save and reuse multiple host configurations • Per-port TCP or UDP selection • Configurable inter-packet delay and socket timeout • Live per-port result display • Clean SwiftUI interface, native look and feel • No tracking, no analytics, no accounts HOW IT WORKS Port knocking is a technique for opening firewall ports on demand: your server watches for a specific sequence of connection attempts (for example, TCP/7000, UDP/8000, TCP/9000), and only opens a protected service like SSH after seeing the right pattern. knock(1) lets you send those sequences from your phone, allowing you to connect to your servers on the go. COMPATIBLE knock(1)'s behavior matches the reference jvinet/knock client - if your server runs knockd, knock(1) works out of the box. PRIVACY knock(1) connects only to the hosts you configure. It does not send telemetry, does not use analytics SDKs, and does not require an account. Your saved configurations stay on your device.
