This is result of last week discussion about port knockers.
Its my second bash script (first is my firewall), so any feedback will be appreshiated ;)
usage: ./knocker.sh <config file name> del
Path to config file is constant in knocker.sh.
del - is optional, simply deletes target chain
script has no limits on knock sequences, and demands statefull filtering enabled
ipt -i $IF_INET -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
