Individual packets may be selected to get a drill down and deeper analysis of its contents. Wireshark produces a log, in which each individual line represents one packet that was exchanged. As you gain a clearer idea of the specific types of traffic you want to monitor, you can use the Filters feature to exclude certain types of traffic, or include specific kinds of packets. Once you’ve clicked Start, you’ll see network traffic movements in real time – and be able to stop Wireshark from running manually, if you haven’t configured an automatic stop. Select the interface you want, then click Start. The Options menu enables you to specify the length of time that Wireshark should run for, or the amount of data it should capture before it stops. Once you’re clear on what you hope to achieve with the software, you can begin capturing network traffic by choosing Capture, then Options. You should use port mirroring, if you wish to examine traffic on an Ethernet port other than the one your Wireshark system is plugged into. If you just need to isolate and check up on local conditions, plugging the system on which Wireshark is installed into the relevant switch port will enable you take readings on the hardware addresses associated with that port, broadcast/multicast traffic, and traffic passing to and from the system between ports. To get the most out of this utility, you’ll need to plan ahead a little – mostly to determine what it is that you actually want to monitor. Wireshark is designed to capture and log the activity on your network in real time, so that you can sort through and analyze the results in your own time.

If you haven’t done so already, the first thing you’ll need to do is install Wireshark on your testing system. Here are some tips and best practices, describing how. The utility provides a detailed report on the traffic flowing through your Network Interface Card (NIC), and may be used in benchmarking network performance and troubleshooting network issues. The flag section has the following parameters which are enlisted with their respective significance.Wireshark is distributed as a free open source packet analyzer.

Header length: It is the length of the TCP header and can vary from 20 to 60.Ī major section of this TCP packet analysis is the flag section of a packet which gives further in-depth information about the packet.

Acknowledgment number: It contains the byte length of data received.

Next sequence number: It is the sum of the sequence number and the segment length of the current packet.

Sequence number: It is a method used by Wireshark to give particular indexing to each packet for tracking packets with ease.

TCP segment length: It represents the data length in the selected packet.

Destination port: This is the port of the destination server.

Source port: This is the port of your host network used for communication.

Let’s look at each one of them and their significance: Now to examine a packet closely we shall select a packet and in the expert view in the packet detail section just below the packet list we shall be having the TCP parameters as you can see in the below diagram. ACK, SYN, SYN-ACK is listed on their respective side. You can observe these three steps in the first three packets of the TCP list where each of the packet types i.e.
