A trigger wihch can generate choreographed TCP packets to Remote include PAWS.

Preparation for Client(especially IPtables command) and Server can be found by annotation of each function

make

sudo ./nettrigger --help

If you want PAWS happended in Server 2.2.2.2

Client Preparation

sudo iptables -t filter -I OUTPUT -p tcp --sport 12345 --tcp-flags RST RST -j DROP

Send Tcp Packet

# assume the Address of eth0 is 1.1.1.1 and the 12345 is what you want use  
# assume server address is 2.2.2.2 whose HTTP server run on 9999
sudo ./nettrigger -i eth0 -s 1.1.1.1:12345 -d 2.2.2.2:9999 -action paws

It will first generate TCP connection with Establish for Server, then send BAD HTTP content(Default content is "474554202f20485454502f312e310d0a0d0a", -d "your hex data" could be used if you want) Then Server close the connection with 4-way handshake. Finally Client send choreographed TCP SYN packet to make PAWS happen.
