BARRICADE v0.1.0rc2 |
Welcome to barricade, a simple implementation of the port 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 password. ChangeLog Click here to view the changelog Download Here you can find the source code tarball or the binary debian package for Woody. Tarball Installation 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/. Debian Installation Download the tarball then run make deb dpkg -i barricade-0.0.1.deb to install barricade on your debian distro. dpkg will select the package libpcap0 automatically (debian rules ;)). The configuration file is /etc/barricade.conf. After editing this file, run /etc/init.d/barricade start to start daemon.
