MicroNugget: How to Use Wireshark with GNS3

In this video, Keith Barker covers using the protocol analyzer Wireshark on GNS3. Because so few people know how to use the protocol analyzer for sniffing packets or figuring out what's happening on a network, it often goes unused, even though Wireshark comes native on GNS3 installations for Windows.

A protocol analyzer like Wireshark is great in live, production environments, but it might be even more valuable in a learning environment. With Wireshark set up, it's easy to test hypotheses about what's happening on a network, which protocols are being used, and what the effects are that are moving downstream. Even better, since Wireshark gives a graphical representation of each and every frame, packet and segment, you can use it to verify your own understanding of network traffic. You can analyze a network node or connection, see each element of the source, destination, and protocol to see if it makes sense. Keith demonstrates first hand how easy it is to set up and configure Wireshark and display the results of its packet sniffing.

Thanks for the feedback Wairisson. I appreciate it. Happy to know you are enjoying the videos, and I will consider the pace for future videos. Have you seen any of the full series of videos on CBT Nuggets or just the Micro Nuggets here on YouTube? The series are not so fast paced. Thanks, Keith

[KeithBarker]

Thanks Wairisson- I will slow it down a bit. I appreciate you letting me know.

thank you very much for the incredible me i was thinking about it that there must be a way so that i will be able to capture the traffic but i was using packet tracer, and i search it on you tube and now you know what i got great Keith Barker...

This was great help thanks Keith!!... I had just installed the new gns3 and for some reason it will not support or install WireShark on windows 7 anymore. I did read they only support windows 10 pro now. But I installed WireShark separately from the GNS3 install and was able to launch a packet capture and see BGP exchanging keep alives as well as seeing my pings between routers. Thanks!!!

I watch a CCNA Sec series, it´s awesome classes

[carlitosvodka]

how can an end user like me observe which peckets go in and out of my laptop when i connect to an application like wow or lol?

[darkknight]

Is this still relevant after almost 10 years? I mean is this video still relevant after some changes over the past few years?

[fallofdutee]

shame GNS3 (2.2) won't allow recapture after taking one - get pcap error and have to close Wireshark completely. Needs fixed

[TheJyer]

how did you do that windows xp inside gns3?

[wairisson]

Keith you classes are amazing but i´m from Brazil and don´t speak english so good, so i would like to ask you to speak a little more slow, it will help a lot to undestand you classes
Rds.
