doing this this requires admin access on network device.
in brief :
* lets say a switch a 10 ports and you can configure lets say port 7 to
get copy of data passing through other ports by configuring port
mirroring to port 7.
* connect a second nic/ethernet card on a machine and connect to port
7 of switch.
* now if you capture the packets on second nic on the machine you can
capture all the packets going through the network.
you can find a lot of help just search for "how to setup Port mirroring"
on google
