Hi, Everyone:
I am having difficulty displaying the pattern data
inside a 'ping' packet using 'tcpdump'.
I am sending a periodic 'broadcast' padded with 'data':
ping -f -i 3600 -p 204445204E43385120 #" DE NC8Q "
I want to display this data on a console. I am using
'tcpdump -i eth1 -v -X'
but this shows too much data/activity.
'tcpdump -i eth1 -v -X port 7' displays nothing.
Perhaps something other than 'tcpdump' would be more suitable?
1. How can I display only the 'echo request' packets?
tcpdump icmp[icmptype]=icmp-echo -v -X
2. How can I display only the 'echo reply' packets?
tcpdump icmp[icmptype]=icmp-echoreply -v -X
