Be sure to set the -s option ("snaplen") to zero so that you capture
all of the activity. Many people forget this and only capture the
headers a few bytes of the payload itself. Under Linux and a stock
ethernet card, you'd want:
tcpdump -i eth0 -s 0 -n -w dumpfile.pcap
If you are doing this on a gateway, you may want to specify some
filters so that only your attack network is captured. e.g. if my
attack network is 200.100.50.0/24,
tcpdump -i eth0 -s 0 -n -w dumpfile.pcap net 200.100.50.0/24
