Question

what's difference between network analyzer and packet sniffer?

Answer 1

network analyzer, also called packet sniffer, network sniffer , packet analyzer, protocol analyzer. or sniffers.



which is computer software or computer hardware that can intercept and log traffic passing over a digital network or part of a network.[1] As data streams flow across the network, the sniffer captures each packet and eventually decodes and analyzes its content according to the appropriate RFC or other specifications.



Uses



The versatility of packet sniffers means they can be used to:



* Analyze network problems

* Detect network intrusion attempts

* Gain information for effecting a network intrusion

* Monitor network usage

* Gather and report network statistics

* Filter suspect content from network traffic

* Spy on other network users and collect sensitive information such as passwords (depending on any content encryption methods which may be in use)

* Reverse engineer proprietary protocols used over the network

* Debug client/server communications

* Debug network protocol implementations

Answer 3

One more than likely a network analyzers gives you the whole network make up...such as the topology, similar to commands through a router such as show neighbors...



A packet sniffer is more of a troubleshooting tool to view the traffic in your network.

Answer 4

the main extreme distinction is... you meant tcp not tcp/ip i think of. the two tcp and udp are techniques of sending archives over a tcp/ip link. tcp is a protocol which skill the sending device *knows* the tips substitute into won. The receiving device recognizes receipt. Any lost packets or broken packets are re-despatched so as. udp is a protocol which skill the sending device knows not something approximately what exceeded off to the tips. Any lost or broken packets, too undesirable, they are lost. So, that's rather like 'recorded transport' (signed for) as against basic mail. they are often used for the ideal style of archives pass... in case you will desire to realize it have been given there properly it makes use of tcp and in case you do not would desire to understand then it makes use of udp. So 'echo' makes use of udp... using fact the tip device will deliver you a respond independently of the unique message... if it gets it. So html makes use of tcp to confirm you spot each and every of the information.

Answer 5

Pretty much just the name. Infact most utilities that are one are both.
