Hi everyone!

How can I get response time difference between GET and HTTP/1.0 200 OK (i mean time latency of web-server) with using of tshark&shell or something else for each hostname from pcap file?
What can you recommend me to do that?

You can use:

zrt=$(
  (
    printf "GET / HTTP/1.0\r\n\r\n"
    sleep 5
   ) | telnet ... | timex sed -n '/ 200 OK/q' 2>&1 )
