hi sirs,
apologize me if i posted to the wrong list.
here is my machine
bank@/tmp# uname -a
FreeBSD bank.thai-aec.org 4.8-STABLE FreeBSD
4.8-STABLE #2: Sun Jun 1 18:59:28 ICT 2003
root@bank.thai-aec.org:/usr/obj/usr/src/sys/Bank i386
bank@/tmp#
i read tcpdump man page and find that the b option
written in description is conflicted to synopsis.
please have a look from man page below
NAME
tcpdump - dump traffic on a network
SYNOPSIS
tcpdump [ -adeflnNOpqRStuvxX ] [ -c count ]
[ -C file_size ] [ -F file ]
[ -i interface ] [ -m module ] [ -r
file ]
[ -s snaplen ] [ -T type ] [ -w file ]
[ -E algo:secret ] [ expression ]
DESCRIPTION
Tcpdump prints out the headers of packets on
a network interface that
match the boolean expression. It can also be
run with the -w flag,
which causes it to save the packet data to a
file for later analysis,
and/or with the -b flag, which causes it to
read from a saved packet
file rather than to read packets from a
network interface.
bank@/tmp#
i try -b file and got error but -r file give me a good
result.
