There is a switch-based LAN without encrypted traffic. I want to sniff ALL its traffic (ARP, TCP, ICMP, etc.) by plugging the laptop into one of the switch port. Then run the software on the PC to sniff the network traffic.
Of course I will provide an authorized IP address to my laptop. It is an authorized test in lab environment.
How can I do the sniffing? What sniffing software should I use?
