Grab traffic from locations other than your local computer and the system it talks to: Wireshark cannot grab traffic from all of the other systems on a network.

Help a user who doesn’t understand network protocols: Users must first know how a network operates in order to use Wireshark.

Wireshark can help troubleshoot many network issues, and it can be used as an educational tool.

Network users learn about a specific protocol.

Developers debug protocol implementations.

Security engineers examine security issues across a network.

Network administrators troubleshoot problems across a network.

Wireshark can be used to understand how communication takes place across a network and to analyze what went wrong when an issue in communication arises. The filters in Wireshark are one of the primary reasons it has become the standard tool for packet analysis. For example, you can set a filter to see TCP traffic between two IP addresses, or you can set it only to show you the packets sent from one computer. Wireshark allows you to filter the log before the capture starts or during analysis, so you can narrow down and zero in on what you’re looking for in the network trace.

To see traffic to an external site, you need to capture the packets on the local computer.

It captures network traffic from ethernet, Bluetooth, wireless (IEEE.802.11), token ring, and frame relay connections, among others, and stores that data for offline analysis.Įditor’s Note: A “packet” is a single message from any network protocol (e.g., TCP, DNS, etc.).Įditor’s Note 2: LAN traffic is in broadcast mode, meaning a single computer with Wireshark can see traffic between two other computers. Wireshark is a packet sniffer and analysis tool.

Using Wireshark to look at packets without permission is illegal. You should only use Wireshark on networks where you have permission to inspect network packets. There truly isn’t a better way to learn low-level networking than to look at traffic under the Wireshark microscope. Government agencies, corporations, non-profits, and educational institutions use Wireshark for troubleshooting and teaching purposes.

Wireshark is the de facto, go-to, you-need-to-know-how-to-use, application to capture and investigate network traffic.Īnd because Wireshark is the predominant tool for this job, let’s go over some application basics, such as where you can download Wireshark, how to capture network packets, how to use filters, and more. If you find yourself troubleshooting network issues, and you have to inspect individual packets, you need to use Wireshark.
