barricade is a simple implementation of the door knocking method aimed to open your network service or firewall only if a special ICMP echo request packet is sniffed from the network interface. After the last valid packet received, barricade waits for a defined amount of time, then it closes your firewall or stops your services. There is a client included in the package called barricade_client that helps you to create special icmp packets containing the system password.

To compile barricade you need gcc and libpcap headers (>= 0.6.2). Simply run
make

to compile the program and
make install

to install. Installation paths are defined in ./scripts/install.sh. This script is suitable for debian users (and perhaps for many other distros) but you may need to edit some parameters. Don't forget to edit uninstall.sh to reflect changes made on install.sh if you plan to uninstall barricade. ./etc/barricade.conf is a sample configuration file, with comments. Edit this file to suit your needs and put it on /etc/.
