Hi,
I tried the command you gave joan but it gives me an error  stating
'head' is not an internal or external command,operable program or batch file.
What may be the error?
 
cheers

Well, I've tried something else: custom columns:

$ tshark -o column.format:""No.", "%m", "Time", "%t", "Source", "%s", "Destinat
ion", "%d", "Protocol", "%p", "srcport", "%uS", "dstport", "%uD", "len",
"%L",
"tcp.flags.ack", "%Cus:tcp.flags.ack", "tcp.flags.syn", "%Cus:tcp.flags.syn""

* and Yes, you've got your protocol
** but it doesn't show the boolean value of the tcp.flags (just set or nothing)

BTW Wireshark gives the same result.
