replays last FIN-ACK in order to check if the other side correctly implements TIMED-WAIT. other side should be first to close the connection. with http this can be done in curl by forcing http/1.0 mode.

curl -0 -d 'lolol=lololol' http://TARGET/wtwtwt
tcpdump -S 'tcp port 80' -l | ./replayer.rb TARGET 80 YOUR_HOST_AS_APPEARS_IN_TCPDUMP

Example of it working and showing the other side correctly handling TIMED-WAIT:

root@midway:~# tcpdump -S 'tcp port 80' -l | ./replayer.rb 173.194.41.67 80 ip-10-250-157-181.eu-west-1.compute.internal
OMG IM RUNNING

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
