Good morning,
Do newer version of tcpdump no longer show TCP sequence numbers without the -vv
flag? Or is this some kind of FreeBSD bug?
FreeBSD 7.2 (tcpdump 3.9.7):
07:06:47.765297 IP x.x.x.x.58894 > 209.87.252.181.443: P 285:344(59) ack 1589
win 16695
07:06:47.827029 IP 209.87.252.181.443 > x.x.x.x.58894: P 1589:1648(59) ack 344
win 33580
07:06:47.861615 IP x.x.x.x.58894 > 209.87.252.181.443: P 344:1117(773) ack 1648
win 16680
07:06:48.114280 IP 209.87.252.181.443 > x.x.x.x.58894: . ack 1117 win 33580
FreeBSD 8.x (tcpdump 4.0.0):
07:10:17.303178 IP x.x.x.x.4433 > 209.85.225.105.80: Flags [.], ack 1391, win
64512, length 0
07:10:17.307536 IP 209.85.225.105.80 > x.x.x.x.4433: Flags [.], ack 621, win

07:10:17.308729 IP x.x.x.x.4433 > 209.85.225.105.80: Flags [.], ack 1391, win
64512, length 0
07:10:17.340326 IP 209.85.225.105.80 > x.x.x.x.4433: Flags [.], ack 621, win
9648, length 1390
07:10:17.340330 IP 209.85.225.105.80 > x.x.x.x.4433: Flags [.], ack 621, win
9648, length 1390
07:10:17.341588 IP x.x.x.x.4433 > 209.85.225.105.80: Flags [.], ack 4171, win
64512, length 0
To me the 3.9.7 output is much more useful.
