Build TCP/IP packet from scratch by ruby , and send syn(or whatever you want) packet
#!/usr/bin/env ruby
# Full Contol on Ethnet, IP & TCP headers. Play with it ;)
# to test it: nc -lvp 4444
# as root: tcpdump -nvvvv 'tcp port 4444' -i wlan0 # change wlan0 to your interface
# or use packetfu to monitor as tcpdump
## cap = PacketFu::Capture.new(:iface => 'wlan0' , :promisc=> true)
## cap.show_live(:filter => 'tcp and port 4444')
# libpcap should be installed
# gem install pcaprub packetfu
