I ran the daemon in debug mode but still no luck:

# fwknopd --debug
[+] ** Starting fwknopd (debug mode) **
[+] Building iptables config info.
/sbin/iptables -t filter -n -L INPUT
[+] starting fwknopd
[+] flushing existing iptables IPT_AUTO_CHAIN chains
/sbin/iptables -t filter -n -L FWKNOP_INPUT
/sbin/iptables -t filter -F FWKNOP_INPUT
/sbin/iptables -nL INPUT
[-] warning, could not find iptables state tracking rules in INPUT chain
[+] imported access directives (1 SOURCE definitions).
[+] Sniffing (promisc) packet data from interface: eth0
[+] pcap_loop()

After a good knock sequence is received this is all the output that I 
see from fwknopd in debug mode.
