	Packet sniffer - Wikipedia, the free encyclopedia
		A Packet sniffer (also known as network or protocol analyzer or Ethernet sniffer) is computer software (usually) or computer hardware that can intercept and log traffic passing over a digital network or part of a network.
		A packet sniffer for a token ring network could detect that the token has been lost or the presence of too many tokens (verifying the protocol).
		A packet sniffer could detect that messages are being sent to a network adapter; if the network adapter did not report receiving the messages then this would localize the failure to the adapter.

	Sniffers: What They Are and How to Protect Yourself
		A sniffer is a piece of software that grabs all of the traffic flowing into and out of a computer attached to a network.
		A sniffer is one of the first things a cracker will load to see what is taking place on and around their newly compromised machine.
		Sniffers are an outstanding resource for the curious beginner, who hopes to understand both networks and security.

	What is sniffer? - a definition from Whatis.com
		A router with a sniffer, however, may be able to read the data in the packet as well as the source and destination addresses.
		Sniffers are often used on academic networks to prevent traffic bottlenecks caused by file-sharing applications.
		The generic term may have originated from Sniffer, which is said to be the first packet capture and decode software that was offered for the purpose of network analysis and troubleshooting.

	computer-security/sniffers FAQ
		One special sniffer, called Esniff.c, is very small, designed to work on Sunos, and only captures the first 300 bytes of all telnet, ftp, and rlogin sessions.
		This posed a big problem when trying to find a sniffer to examine the network problems we were having, since I found that some sniffers that understood Ethernet II parse out some 802.3 traffic as bad packets, and vice versa.
		One of these other sniffers in particular was reporting a large number of bad packets with src mac addresses of aa:aa:aa:aa:aa:aa but I don't see them at all using the MS product.

		A sniffer is a program that puts a NIC (Network Interface Card), also known as an Ethernet card, (one of the necessary pieces of hardware to physically connect computers together) into what is known as promiscuous mode.
		A sniffer being used on a network to snoop passwords and anything else is considered to be a passive attack.
		This sniffer is not a general purpose sniffer but rather a program that will set out to specifically sniff the challenge/responce portion of a PPTP (Point to Point Tunneling Protocol) and then the captured data can be feed into a password cracker.

	Maximum Security - Chapter 12 - Sniffers
		A sniffer must be located within the same network block (or net of trust) as the network it is intended to sniff.
		Sniffers were designed by those aiding network engineers (and not for the purpose of compromising networks).
		Sniffers now exist for every network platform, but even if they did not, they would still be a threat to you.

	What is Network Sniffer
		The price of portable network sniffer is ranged from a few hundred dollars to tens of thousands dollars, depends on who is the vendor, the network type (Ethernet, Gigabit Ethernet, Optical media WAN links etc.) and the types of data analysis are done.
		Distributed network sniffers have two part: Monitoring Probe which is a device deployed at various point of the network and a Consol which is a software package installed in the Network Operation Center (NOC) to centrally monitor all Probes.
		The distributed network sniffers are typically deployed by large enterprises to monitor their network from a centralized location such as NOC.

	Network Sniffers
		IDS like snort are pretty convenient as sniffers for complex situations, especially those thatrequre sophisicated filtering as they have advanced filtering capabilities far superior then Tcpdump or snoop.
		Sniffer programs are a data interception technology that increase the risk of so-called "man-in-the-middle" attacks, and with the recent release of dsniff 2.3, security specialists need to be more aware of it than ever.
		A sniffer could help defend against this kind of attack by listening for these aberrant ICMP packets, disposing of them before they could overwhelm a server, and hopefully establishing their source.

	Understanding Database Sniffers
		Sniffers are network monitoring tools, while the spy programs are client-side tools.
		Database sniffers are protocol analyzers that include recognition of higher-level proprietary client/ server protocols such as Oracle TNS (Transparent Network Substrate) or SQL Server TDS (Tabular Data Stream).
		The Sniffer user can also specify a filter such as a hexadecimal data pattern that will trigger the capture of data for a given period of time.

		Sniffers were originally developed by programmers around the world to be used as a tool for debugging network problems.
		Sniffers capture the data being sent across the network in a very raw form, so in effect one is examining the packets traversing in the rawest form and using the information gathered by the analysis to detect or troubleshoot networking problems.
		However, in case of Ethernet-based Sniffers, the Network Interface cards are set to a special state called the promiscuous mode to ensure that it receives all the packets within listening range of the listening system.

	Information Security Glossary - Sniffers
		A sniffer is a program which captures and analyses packets of data as it passes across a network.
		They are used by network administrators who wish to analyse loading across network segments, especially where they suspect that spurious packets are 'bleeding' from one network to another.
		The other use of sniffers is by connecting to the Internet then capturing data; such data can include user names and passwords.

		It uses sniffer servers that can be installed and run on remote hosts, and will dig through local network traffic, useing custom pattern/keyword matching to find packets with interesting content, which are then forwarded to a central loghost on which the logging daemon is run that gathers and logs the data.
		For stealth purposes, Sniffers and the logger communicate via random protocols and encryption, and are compatible to many Unix systems and NT.

	Desert project fuels hopes for young sniffers - National - smh.com.au

		And when they returned to Yuendumu the elders made sure the former sniffers were kept busy with a program of activities.
		According to a joint submission to the inquiry by the Federal Department of Health and Ageing and the Department of Immigration and Multicultural and Indigenous Affairs, the Mount Theo experiment reduced the number of sniffers in Yuendumu from 70 to zero within a decade.

		One word of caution is that Ethereal has suffered from dozens of remotely exploitable security holes, so stay up-to-date and be wary of running it on untrusted or hostile networks (such as security conferences).

		It may not have the bells and whistles (such as a pretty GUI or parsing logic for hundreds of application protocols) that Wireshark has, but it does the job well and with fewer security holes.
