I'm using tcpdump for some tests I want to see the IP and port number but the output of tcpdump is like
IP pl1snu.koren.kr.http > kitch.pl.sophia.inria.fr.dnp: Flags [P.], seq 54:72, ack 1, win 5792, length 18
it only shows the hostname and the protocol for http, it is easy to know it is 80 but for dnp I have to search
so is it possible to how to make tcpdump to display ip and port number but not hostname and protocol if so , how? thanks
