geffner@ubuntu:~$ mkfifo pipe
geffner@ubuntu:~$ # Create our openssl client, which will receive input from our pipe
geffner@ubuntu:~$ openssl s_client -ign_eof -connect example.org:443 > /dev/null 2> /dev/null < pipe &

geffner@ubuntu:~$ # Begin writing the request to our pipe
geffner@ubuntu:~$ printf "GET / HTTP/1.0\nHost:example.org\n" > pipe
geffner@ubuntu:~$ # Begin logging the SSL traffic for our openssl client process
geffner@ubuntu:~$ python ssl_logger.py -verbose 98954 &
