The software is particularly interested in traffic throughput and a display of traffic per protocol. Data can be viewed as lists of protocols and their throughput or as live graphs and charts. Packets captured with the Capture Engine can be stored for analysis or replayed across the network for capacity testing. Omnipeek installs on Windows and Windows Server. However, it is possible to get Omnipeek on a day free trial.
The fundamental tool of almost all network traffic collection is tcpdump. It is an open-source application that comes installed on almost all Unix-like operating systems. Tcpdump is an excellent collection tool and comes complete with a very complex filtering language. Capturing all data from a network device on even a moderately busy network can create too much data to analyze efficiently.
For example, in writing this article, I captured some traffic and noticed that my machine was sending traffic to an IP address I did not recognize. It turns out that my machine was sending data to a Google IP address of Since I did not have any Google products running, nor Gmail open, I did not know why this was happening.
I examined my system and found this:. It seems that even when Chrome is not running in the foreground it remains running as a service. I would not have necessarily noticed this without a packet analysis to tip me off.
I re-captured some more tcpdump data but this time told tcpdump to write the data to a file that I opened in Wireshark more on that later. Tcpdump is a favorite tool among sysadmins because it is a command-line tool. It is unusual for production servers to provide a desktop because of the resources that would take, so command-line tools are preferred.
As with many advanced tools, tcpdump has a very rich and arcane language that takes some time to master. A few of the very basic commands involve selecting the network interface from which to collect data, and writing that data to a file so it can be exported for analysis elsewhere. The -i and -w switches are used for this. The standard TCP capture file is a pcap file. It is not text so it can only be read by an analysis program that knows how to read pcap files. Most useful open source tools are eventually cloned to other operating systems.
When this happens, the application is said to have been ported over. WinDump is a port of tcpdump and behaves in very similar ways.
One major difference between WinDump and tcpdump is that Windump needs the WinpCap library installed prior to being able to run WinDump.
Despite both WinDump and WinpCap being provided by the same maintainer, they are separate downloads. WinpCap is an actual library that needs to be installed. But, once it is installed, WinDump is an. As with tcpdump, WinDump can output network data to the screen for analysis, be filtered in the same way, and also write data to a pcap file for analysis offsite.
It can not only capture data, but also provides some advanced analysis tools. Adding to its appeal, Wireshark is open source, and has been ported over to almost every server operating system that exists. Starting life named Ethereal, Wireshark now runs everywhere, including as a standalone portable app.
The collected packets can then be analyzed all in one spot. At first launch, Wireshark allows you to either load an existing pcap file, or start capturing. If you elect to capture network traffic, you can optionally specify filters to pare down the amount of data Wireshark collects.
One of the most useful tools Wireshark provides is the ability to follow a stream. In the screenshot below we can see a lot of data has been captured, but what I am most interested in is that Google IP address. The same filters and tools that can be used for natively captured network data are available for imported files. TShark is a handy cross between tcpdump and Wireshark. Tcpdump excels at collecting data packets and can very surgically extract only the data you want, however it is limited in how helpful it can be for analysis.
Enter TShark; it captures and analyzes but does the latter on the command line. This command tells TShark only to bother capturing the destination IP address as well as some other interesting fields from the HTTP part of the packet. NetworkMiner is a fascinating tool that falls more into the category of a forensic tool rather than a straight-up network sniffer.
The field of forensics typically deals with the investigation and collection of evidence and Network Miner does that job well for network traffic. Network Miner can also operate in offline mode. You can use the tried and true tcpdump tool to capture packets at a point of interest on your network, and then import the pcap files into Network Miner.
It will then attempt to reconstruct any files or certificates it finds in the capture file. Amazon buys MGM. The Tomorrow War trailer. Half of US adults fully vaccinated. John Cena’s apology to China. Google Doodle celebrates Savoy Ballroom. Windows Windows. Most Popular.

WireShark is relatively new tool in the broad scheme of network diagnostics, and it does a great job finding a middle ground between raw data and visual representations of that data.
It’s got a clean UI, plenty of options for filtering and sorting, and, best of all for some of the multi-platform folks, it jives happily on any of the big three in terms of OS. Add to that the fact that it’s open-source and a Free Sniffer and you’ve got a compelling tool to reach for when you need some quick diagnostics. Tcpdump is something of an older tool and, to be frank, it looks like it. But there’s a certain power in tools that are so cut and dry — it does what it needs to do, does it with as little a footprint as possible, and does it cleanly.
It may be harder for some professionals to weed through the stark tables of data, but in some environments, or on a machine barely running, minimal is best.
It has all the functionality you’d want and need from a sniffer — capturing, recording, etc. Tcpdump is often called for due to its sheer reliability and simplicity.
Kismet is more than just a packet sniffer and, in fact, delves into wide range of functionality. Kismet even has the ability to sniff and analyze traffic of hidden networks or un-broadcasted SSIDs! Tools like this can be strangely invaluable in the right circumstances when there’s something unknown causing troubles and you can’t just find it — Kismet can sniff it out, if it happens to be a rogue network or AP acting up nobody mentioned they setup not quite right. As one can imagine by the nature of wireless networking it’s a little more complex when it comes to sniffing, which is why a specialized tool like Kismet not only exists but is looked to frequently.
Kismet is an excellent go to if you’ve got a lot of wireless traffic and wireless devices and need a tool that’s better suited to handling a wireless-heavy network. The analyzed data is then converted to a human-readable format so that the network experts can analyze the faults in their network.
So, technically, you can view and monitor all that is happening on your network. The below-listed packet sniffing tools are free to use but come with an advisory tag not to use it for malicious purposes. Wireshark is the most popular free packet sniffing tool for Windows and comes as both freeware and premium software with annual subscriptions.
You can download this awesome tool from the official website — wireshark. The captured data is displayed as a sequence of communications between client and server. In order to use this utility, you need to install some compatible drivers on your PC which are loaded by the tool itself.
