• Supports the execution of shell commands on behalf of valid SPA packets

fwknop -C, --server-cmd ## Specify a command that the fwknop server will execute on behalf of the fwknop client

anyone done it yet? Like run a GUI via zenity or fltk-dialog-AppImage so people can send each other some stuff. Like if 2 ppl each run a fwknop and a fwknopd, then they can send chat pop-up-windows to each other.

• The fwknop server can be configured to place multiple restrictions on inbound SPA packets beyond those enforced by encryption keys and replay attack detection. Namely, packet age, source IP address, remote user, access to requested ports, filtering regular expressions against commands, and more.

would be nice to have a GUI for that, or just add one into this project
