Quick answer

Client to send SPA packets to a fwknopd server

F-Droid repository metadata

Allows you to send packets to an fwknopd service to remotely open ports on a Linux machine or a router running OpenWrt. Fwknop2 has the ability to launch an ssh client to start the login process through the newly opened port. It also includes the ability to import keys via QR codes.

How to install

  1. Download the APK from the button at the top of this page.
  2. Allow “Install unknown apps” for your browser or file manager only, not for every app.
  3. Open the downloaded file and confirm the installation.
  4. If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
