Hi there,
I'd like to find out via tcpdump which hosts are directly accessing our
printers.
Therefore, I simply entered
$ tcpdump dst host trota
whith trota being the printer.
The trouble I had was that tcpdump only printed packets sent form the
host actually doing the sniffing.
On entering
$ tcpdump
I get all packets that are either sent or received by my computer or
broadcast packets (e. g. Netbios-datagrams).
My question is whether it's possible to overhear the transport between
two other hosts on the net, e. g.
$ tcpdump host x and y
I tried this on our net but it did not work, as I described above. Did I
use wrong expressions in the command or is this simply not possible?
Cheers,
Florian
