  Packet sniffer - Wikipedia, the free encyclopedia
Packet sniffers (also known as network or protocol analyzers or Ethernet sniffers) are computer software (usually) or computer hardware that can intercept and log traffic passing over a digital network or part of a network.
For network monitoring purposes it may also be desirable to monitor all data packets in a LAN by using a network switch with a so-called monitoring port (it mirrors all packets passing through all ports of the switch).
A packet sniffer could detect that messages are being sent to a NIC, if the NIC did not report receiving the messages then this would localize the failure to the NIC.

 Howstuffworks "How Carnivore Worked"
Computer network administrators have used packet sniffers for years to monitor their networks and perform diagnostic tests or troubleshoot problems.
Essentially, a packet sniffer is a program that can see all of the information passing over the network it is connected to.
When a packet sniffer is set up on a computer, the sniffer's network interface is set to promiscuous mode.

 The Most Powerful Packet Sniffers Available
Packet sniffers can also be used for many types of network analysis including traffic analysis and dropped packet analysis.
Now, if all of the segments were connected to each other through a hub (rather than a switch), a packet sniffer on segment A would see traffic in segments B and C. There are generally only two ways that a sniffer can be used against you.
Once the attacker knows that the victim's machine has been compromised, the attacker could then send another email to the machine with a packet sniffer attached and no one would be there to stop the attacker from installing and using it, that is if the attacker was in the least bit discreet.

 MikroTik RouterOS V2.7 Packet Sniffer
Packet sniffer is a feature that catches all the data travelling over the network, that it is able to get (when using switched network, a computer may catch only the data addressed to it or is forwarded through it)
It allows you to "sniff" packets going through the router (and any other traffic that gets to the router, when there is no switching in the network) and view them using specific software.
The commands are used to control runtime operation of the packet sniffer.

 OptOut -- Packet Sniffing Details and Resources   (Site not responding. Last check: 2007-10-08)
One disturbingly powerful aspect of packet sniffers is their ability to place the hosting machine's network adapter into "promiscuous mode." Network adapters running in promiscuous mode receive not only the data directed to the machine hosting the sniffing software, but also ALL of the traffic on the physically connected local network.
The sort of good news is that, like the original Spynet Sniffer, theirs DOES have a built-in 30-day free trial before it expires, and even more cool, it's 30 actual days of real use, not 30-days from the time it's downloaded.
As it is, it is the packet sniffer I most recommend, although very reluctantly, due to its apparent "malicious hacker" user orientation.

 Packet Sniffer and Network Sniffer
A network router reads every packet of data passed to it, determining whether it is intended for a destination within the router's own network or whether it should be passed further along the Internet.
A router with a sniffer, however, may be able to read the data in the packet as well as the source and destination addresses.

 US-CERT: Welcome to the Reading Room
A packet sniffer is a program that captures data from information packets as they travel over the network.
Other tools are used to construct packets with forged addresses; one use of these tools is to mount a denial-of-service attack in a way that obscures the source of the attack.
A second example is using a packet sniffer to get router or firewall passwords, logging in to the firewall to disable filters, then using a network file service to read data on an otherwise secure server.
