SYNFlood Element Documentation

NAME

SYNFlood — Click element; Generates a SYNflood

SYNOPSIS

SYNFlood(SRCIP, DSTPORT,keywords)

Batching: Batching natively supported
Ports: no inputs, 1 output
Processing: push
Drivers: userlevel

DESCRIPTION

Sequentially emit TCP SYN packets with increasing source port and IP. The 5-tuple space will be scanned in a round-robin fashion. The output packets are ethernet packets with the addresses set to 0.

The source port will be increased until it will reach the 0 value. Then, it will start from a new source IP and generates SYNs for all the ports. When the IP space is finished, it will wrap and start from 0.0.0.1

Keywords:

• SRCIP — Initial Source IP
• DSTIP — Destination IP
• SPORT — Source port. Default is 1000
• DPORT — Initial destination port. Default is 80
• STOP — Stop the driver when the limit is reached. Default true.
• ACTIVE — If false, then do not emit packets until the `active' handler is written. Default is true.
• BURST — How many packets to generate per each iteration. Default is 32.
• LIMIT — Limit the total number of packets to generate. Default is -1 (no limit). The effective number of packets emitted will be the smallest multiple of BURST after LIMIT.
• LEN — The lenght of the generated packets. Default is 60

EXAMPLES

 SYNFlood(10.1.1.1, 172.16.1.1, 1, 80, LEN 1400)
 -> EtherRewrite(11:11:11:11:11:11, 22:22:22:22:22:22)
 -> ToDPDKDevice(0)
