knock(1) vs DappNet

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.

Dapp Net is a private mesh networking app that lets you send encrypted messages and make voice and video calls — with no internet connection, no accounts, and no servers involved. DIRECT. PRIVATE. ENCRYPTED. Every message and call is protected by the Signal Double Ratchet protocol — the same encryption used by Signal messenger. Messages are encrypted on your device before they leave it, and only the recipient can decrypt them. No one else, including us, can read your messages. NO INTERNET REQUIRED Dapp Net connects directly to nearby peers over Bluetooth and Wi-Fi. There are no central servers routing your data. Even in areas with no cellular signal or internet access, Dapp Net keeps working. TRULY PRIVATE BY DESIGN • No account or phone number required • No contact list uploaded to any server • No analytics, ads, or tracking of any kind • All data is stored locally on your device only FEATURES • Encrypted text messaging between mesh peers • Encrypted voice and video calls • Automatic peer discovery over Bluetooth and Wi-Fi • Network topology view — see your mesh in real time • Wormhole attack detection to protect routing integrity • Relay and bandwidth controls • Works completely offline SECURITY Dapp Net is built on open, auditable security standards: Signal Double Ratchet (AES-256-GCM, P-256 ECDH), SAODV hash-chain routing with Ed25519 signatures, and Wormhole Attack Detection and Prevention (WADP)—no proprietary or closed encryption.
