Firewall Tester 0.3 (Development) by Andrea Barisani (http://freshmeat.net/users/lcars/) Friday, October 19th 2001 09:38 Categories: Security, System :: Networking :: Firewalls About: The Firewall Tester consists of two simple Perl scripts: the client part (ftest.pl) and the listening "daemon" (ftestd.pl). The client injects custom packets, defined in ftest.conf, with a signature in the data part while the daemon listens for such marked packets. The scripts both write similarly formatted log files of their activities. If the two scripts are run on hosts on opposite sides of a firewall, then a diff of the two produced files shows the packets that were unable to reach the daemon due to filtering rules. This is not an automated process, and ftest.conf must be crafted for every different situation. Examples and rules are included in the included ftest.conf. Changes: The ability to spoof real connections was added for handling stateful inspection firewalls.
