Hi
I would like to run a command "tcpdump" which (if I understood the
man pages) will enable me to tell which packets came thru' the
router while pretending to be from a machine on the local segment.
The PROBLEM : I get an error message
tcpdump: /dev/bpf0: Device not configured
BTW I'm using FreeBSD 1.1.5.1
Running "MAKEDEV bpf0" does not solve the problem. I cannot run
"mknod" because I don't know all the arguments.
How does one configure the device "/dev/bpf0" ?
Thanks
Leon
