ftp http and other protocols packet transfer
There is a cyber cafe and there are a number of computers connected to a server. Each computer accesses the net through a number of protocols. For e.g., com1 uses http com2 uses ftp and http com3 uses ftp http smtp etc. I need to know how many packets of each protocol are going from or coming to each computer. How can I do it??
Is there a specific method or command for it ??
