A simple script designed to illustrate the DoS SYN Flooding attack. It relies on Perl's RawIP package which can be obtained from CPAN as follows:
or if you are using Debian/Ubuntu:
sudo apt-get install libnet-rawip-perl
To run the script provide source IP, target IP and target PORT and execute with root privileges
sudo perl synflooder.pl 188.8.131.52 184.108.40.206 80
After executing the script, you can observe generated traffic with tshark:
