On the TCP tab click on the
SYN
Flag
. Enter random data for the payload
of each packet. Set the
Nb of packets
to
9999
.
Click the
SEND
button.
*Note:
I have used RafaleX for several years and at times it can appear to be ???buggy???
by not wanting to send packets. The best way I have found to fix this is to
close the program, bring it back up, and try again.
The status bar along the bottom of the application will tell you how many
packets it has sent compared to how many packets it will send.

Practical Hacking Techniques and Countermeasures
Stop the packet capture and the overall results will be displayed.
By clicking on the
Source IP
column the results will filter based on the
source IP of each packet. Fortunately for us, our spoofed packets are listed
first. (You may have to click it twice to get the spoofed packets listed first.)
Denial-of-Service (DoS)
649
By selecting any of your spoofed packets, you can display the details of
the packets in the center section. By dragging the borders of the sections, you
can increase or decrease each section.
In this example, by looking at the center section, we can verify that each
packet was successfully sent with the spoofed source IP address of the target
to the target from port 80 to port 80.
*Note:
This attack can be easily defeated from external attacks by ingress filtering.
