Since data and metadata are unintelligible to humans in their raw state, Wi-Fi packet sniffers are built to decode network packets by transmuting them into a readable format. This can make it easier for administrators to pinpoint the root cause of wireless performance issues and support the ability to fix Wi-Fi issues quickly. Wi-Fi packet sniffers can also contain settings for network administrators to select exactly how much network traffic they want to capture and analyze. Wireless sniffing is an important component of network monitoring best practices.
Sniffing networks, in general, can offer users critical visibility into their networks that can be used to spot network performance issues before they start, but Wi-Fi packet sniffers are designed to take network monitoring a level deeper. In addition to standard network monitoring protocols, wireless sniffers specifically look for packet data and performance metrics related to controllers, clients, and access points.
Wireless sniffing also helps simplify and speed up the troubleshooting process. Wireless sniffer tools are designed to help you pinpoint performance issues, so you can identify what needs to be fixed as quickly as possible.
SolarWinds Network Performance Monitor is a powerful, comprehensive network monitoring tool built to function as an enterprise-grade Wi-Fi packet sniffer for environments of all sizes.
NPM is built to provide network administrators everything they need to achieve full control over their networks in one comprehensive tool. NPM has numerous specialized features to help make wireless sniffing easy. Once these metrics are laid on a timeline, you can spot performance issues more quickly.
If you combine these features with those specific to wireless sniffing, you have the tools you need to achieve gapless wireless network monitoring and wireless packet sniffing. Network mapping is particularly helpful for enterprises with large offices, because this process can help you map out the locations of wireless devices on top of actual floor plan.
NetPath is another mapping feature available in NPM to help you get the most out of your wireless sniffing data. This feature is designed to map out the problem area in your network and displays the most important performance metrics for devices both inside and outside of that problem area. Developed by network and systems engineers who know what it takes to manage today's dynamic IT environments, SolarWinds has a deep connection to the IT community.

It is great for tracking down network problems or monitoring activity. There is a separate Windows port named WinDump. Read 3 reviews.
Kismet is a console ncurses based It identifies networks by passively sniffing as opposed to more active tools such as NetStumbler , and can even decloak hidden non-beaconing networks if they are in use. As you might expect, this tool is commonly used for wardriving. Oh, and also warwalking , warflying , and warskating , etc. Read 2 reviews. Latest release: version KismetR1b on April 8, 8 years, 9 months ago. Ettercap is a suite for man in the middle attacks on LAN.
It features sniffing of live connections, content filtering on the fly and many other interesting tricks. It supports active and passive dissection of many protocols even ciphered ones and includes many feature for network and host analysis.
Read 8 reviews. Latest release: version 0. Netstumbler is the best known Windows tool for finding open wireless access points "wardriving".
The tool is currently free but Windows-only and no source code is provided. Steel Central Packet Analyzer offers an interactive graphical user interface that helps you identify the root network problem using a wide selection of pre-defined analysis views. There are three versions of Steel Central Packet Analyzer that only differs in which products they support. For personal networks, there is the Steel Central Packet Analyzer Personal Edition which offers the same level of packet sniffing but has a limited set of included features.
Steel Central Packet Analyzer Plus is highly recommended for large companies with substantial network traffic since it can support the new Steel Central AppResponse Tcpdump is a command-line tool that was initially designed for UNIX systems and is often pre-installed on almost all Unix-like operating systems. Tcpdump does not have an attractive user interface, but all packet information needed to determine the source of the network problem can be seen on display.
Since it is a command-line packet sniffing tool, you do not need to have a heavy duty PC to run it smoothly, as you can literally fire up the command line tool and start sniffing fairly quickly. There is a bit of a learning curve though and its not nearly as intuitive as other programs in this list. Tcpdump uses very basic to complex codes and commands so it would take time to master how to operate this tool fully.
But once you get the hang of it, it would be straightforward for an IT administrator to get around and identify the causes of network issues. It has been ported to Windows as Windump. NetworkMiner for Windows makes network analysis very simple and can detect the host-name as well as the OS and open ports of network hosts through packet sniffing. NetworkMiner was released in by Netresec and since its release, it has been a widely-used tool by companies and organizations all over the world.
In this day and age where wireless networks are in high demand, Kismet can work wonders in packet sniffing since it was developed specifically for wireless networks. It can detect the presence of wireless APs as well as clients and what kind of traffic they create — this is especially useful for creating WiFi Heat Maps and such.
They both have simple and easy to learn user interfaces. There are also some industry favorites such as tcpdump, Windump, and Wireshark. A packet analyzer captures packets as they travel around the network. Some packet analyzers also include more sophisticated analysis tools.
Packet sniffing can be detected in certain circumstances. The solution to finding packet capture depends on the location of the packet sniffer and the method it uses. Issuing a Ping with the right IP address but the wrong MAC address for each computer on the network should spot the hosts that are in promiscuous mode and therefore likely to be in use for packet sniffing. Full packet capture copies all of a packet including the data payload.
Typically full packet capture data gets stored in a file with the. Allowing IT department staff to use full packet capture capabilities can break the confidentiality of data held by the enterprise and invalidate data security standards compliance.

The main benefits are that they: Identify congested links Identify applications that generate the most traffic Collect data for predictive analysis Highlight peaks and troughs in network demand The actions you take depend on your available budget.
Promiscuous mode It is important to understand how the network card on your computer operates when you install packet sniffing software. Network traffic types Network traffic analysis requires an understanding of how networking works. Hacker tools Packet sniffers are also used by hackers. Invest in intrusion detection systems to protect your network from these forms of unauthorized access How do Packet Sniffers and Network Analyzers work?
What should you look for in a packet sniffer? We reviewed the market for packet sniffers and analyzed the options based on the following criteria: The ability to read packet headers and identify source and destination addresses A protocol analyzer that can categorize traffic by app The option to capture all packets or sample every nth packet The ability to communicate with switches and routers through NetFlow and other traffic analysis protocol languages Capacity planning and traffic shaping tools A free trial period or money-back guarantee for no-risk assessment A free tool that is worth installing or a paid tool that is worth the price.
