Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn

ssh: connect to host x.x.x.x port 22: Operation timed out
I tried 2 port knocking utilities, thinking something was wrong with the first one then I installed knockd on debian server, same command, no luck, I'm thinking nmap is not the utility to be using.
/etc/knockd snippet:
[openSSH]
sequence = 22,1,2,3,4
seq_timeout = 5
command = /sbin/iptables -A INPUT -s %IP% -p tcp --dport 22 -j ACCEPT
tcpflags = syn
Should I change the config to look for UDP packets instead or something?
