- A syn flood is based on the TCP/IP 3way handshake...where a computer
- sends a syn packet to a host it wishes to connect...(basically saying
- "Hey I wanna connect!") and the host send a Syn/Ack back (saying: "Yeah
- sure you can connect...just let me verify its you") then normally you
- would send back an ACK (saying: "yeah its me! IP 206.79.289.19 [as an
- example IP])...now in a syn flood attack you wouldnt answer to the last
- question (the ACK you send saying Yeah its me) and you keep asking to
- connect but w/o showing proof its you...so the server just sits there
- yelling out over the Inet "where are!!" expecting an ACK packet from you
- at anytime...you need software to execute this D-O-S attack and it is
- very very very bad you fill the ports of your target and noone else can
- connect to it...please DO NOT DO IT!!!
