For example, if you want to capture traffic on your wireless network, click your wireless interface. Capturing PacketsĪfter downloading and installing Wireshark, you can launch it and double-click the name of a network interface under Capture to start capturing packets on that interface. Don’t use this tool at work unless you have permission.

I can also find discussion of individual fields on forums/blogs, but with 273+ fields to try to understand, I'm wondering if there is a better resource I haven't yet found that is available.Just a quick warning: Many organizations don’t allow Wireshark and similar tools on their networks. My question is, is there a cheat sheet for newbies/non-network engineers with such information? Thus far, it seems like in-depth explanations can occasionally be found in the Wireshark documentation, albeit spread across many chapters. why might it matter if a bit is reserved or not?' Such a definition doesn't answer critical questions like, 'what is the range of integers for ip.flags and what would be the significance of each? Or, 'what is the significance of a 1 for ip.flags.rb as opposed to a 0, i.e. Ip.flags.rb Reserved bit Boolean 1.0.0 to 3.2.2 ) and the definitions are: ip.flags Flags Unsigned integer, 2 bytes 1.0.0 to 3.2.2

I have reviewed the Wireshark documentation (.

It's been a laborious process of Googling each filter from the tsharkoutput to build an intuitive understanding of each field, two fields just to illustrate my point: 'ip.flags.rb' or 'ip.flags.' While the shorthand of such fields may have more meaning to an experienced network engineer, most is lost on me. I am a data scientist analyzing packet data from Wireshark but I do not have a networking background.
