Ferramenta muito similar a outros flooders Sys TCP. Essa trabalha mandando pacotes Sys ao host e a porta específicada. Diferente de outros flooders, Synner consome toda a conexão.

Use: ./synner.pl IP PORTA TEMPO
Ex.: ./synner.pl 200.151.20.141 80 10

É necessário que você tenha o Net::RawIP instalado.

Perceba:

# WARNING: Never tested in real world :}

Garanto que eu também não testei, mas existe um comentário na Securiteam que é uma ótima ferramenta.

# 
# Description: 
# This small tool is similar many other tcp syn flooders out there. 
# It works sending syn tcp packets to destination host:port, 
# spoofing it`s own ip addresses by sending randon source host:port 
# packets. 
# Be carefull, becouse you really need strong link otherwise 
# you`ll get f*. Unlike panic.pl , synner.pl consumes much 
# bandwidth resources. 
# 
# Required: 
# Install Net::RawIP from cpan or get it`s .tar,gz from somewhere. 
# It`s up to you. 
# 
# This tool does SPOOF your ip. 
# 
# Run it as ROOT (Net::RawIP needs). 
# Usage: ./synner.pl <ip> <port> <time> 
#

@iparray_round2 = (0,1,2,3,4,5,6,7,8,9);
