Configure iptables:

Run Portspoof with service emulation:
Run Portspoof with service emulation in daemon mode:
$ portspoof -c /etc/portspoof.conf -s /etc/portspoof_signatures -D
This mode will generate and feed port scanners with bogus service signatures.
Run Portspoof in daemon "open port" mode:
$ portspoof -D
This mode will just return OPEN state for every connection attempt.
3. Add portspoof invocation to your system's startup scripts.
