Problem resolution is the first use of sniffing, and it's still one of their biggest uses. Sometimes, network problems arise ” anyone who has ever played with a network for more than five minutes is well aware of this. A sniffer lets you look at the individual packets and see what's going wrong. Maybe a switch is mangling a specific field in each packet, or maybe an NIC is throwing out nonsense packets at a frantic rate ”a sniffer will let you see those things and let you see them quickly.
