- Packet analysis is hard enough. Avoid these common mistakes that make it even harder. I know... because I have made every single one of them! Comment below with mistakes you have made and how you overcame them - c'mon, be honest! :-)

I thought it was hard the few times I've used it--but watching you, I'm finding that it really isn't as hard as I thought.. Thanks for another great video!!
Awesome Dwayne! Just wanted to share some of my blunders.
@@ChrisGreer Sharing our blunders makes IT (pun intended) easier for the next person. :)
@@dwaynesudduth1028 Nice! Well placed pun. 👏
he just has a gift. every single word being said matters
Learned something new, Thanks Chris! Can you talk more about how to setup capture mid network with a tap device so you don’t experience those large segments when capturing at the end point?
Hey Hussein! You bet - absolutely a good topic. I'll get that one shot and posted too. Thanks for the comment!
@@ChrisGreer Do you prefer active or passive taps (like the Throwing Star Lan Tap from Hak5)? or do they both have their place? I've only ever used Wireshark on a mirrored switch port, the few times I've used it--or the captures I've looked at have been captured that way.

Work with wireshark on the daily and this video made me smile. Have seen these all so many times.
I know, me too!
Thank you as always Chris for the best Wireshark Instructor in the world! Most comprehensive.
Wow, thanks!
So cool. I understood slightly more than half of this lesson.
Still loving it Chris. I’m not using Wireshark nearly as much as I was in Networking. I still tell people to slap Wireshark on an issue and look at it. So, thanks for doing what you do because I send folks right here to your channel to learn.
Thanks for the mention Kennyon!
You are amazing! Your content on TH-cam and Pluralsight is awesome. Thank you
Wow, thank you! I appreciate the feedback and thanks for the kind comment.
hey this is a seriously important learning resource, thank you
Thanks for the comment!!
thank you Chris !:) you’re making it clear, have a nice day
Thank you!
your teaching way is far better than others..thank you for providing good knowledge ...also can you please tell how one can see the data in the payload?
Thank you so much for all the content you are posting on this channel !
Thanks for the comment!
Wow Chris this is very helpful stuff. Thank-you for sharing all this
Glad it was helpful!
Often times when capturing on a client I’ll also run a procmon trace of network traffic to make it easier to figure out which process is associated with which conversations. That easy correlation is a big reason I was starting to use Message Analyzer and why disappointed it got discontinued.
As always, awesome video. Thank you Chris
You break it down to the simplistic, thanks.
You're welcome!
Great video! More "false-alarm" tips when troubleshooting please!
I’ll keep it up!
Hi Chris, how we understood all of these Tools and how something has to look like.How becomes somebody professional?
Hey, I love your videos. You explain very clearly and you explain it really well. Thank you.
Thank you!
Excellent tips. Thank you for sharing.
My pleasure!
Great tips Chris! Thank you for sharing.
You bet!
Sometimes issues are so intermittent that they can take days to reoccur and not be so bad that end users will notice. In this instance ring buffers are perfect but in addition, using a script to monitor a log file for a specific string which would occur after the event, upon which stops the capture is great for preventing overwriting of capture files.
I like it, great idea with the scripting.
Being hit with a payload around 12-1pm daily. Captured it several times. Anyway, to figure out what the payload was designed to do?
You are awesome bro..each of your video is like a gold🥇👏
Thank you so much 😀
Chris Greer's content is full of gems.
Thanks Carl!!
Great video!
Glad you enjoyed it!
You mentioned taps, what model would you recommend ?
Hey James! I would recommend the Dualcomm Tap - amzn.to/3qdCfrn (Affiliate Link Alert!) But it's the best, cheapest, good-ole tap I know of that I can toss in my backpack. For heavier lifting - check out www.profitap.com. They have AWESOME stuff for tapping as well as hardware-based packet capture. And they are just cool people too.
useful as usual
Thank you for another great video.
Thanks for watching!
hello, I want to ask, when a mitm occurs, there are 3 incidents, where there is normal data, attack data and combined data between normal data and combined data, my question is how to find out the normal data.
I would like to know how to define my own custom protocols and have Wireshark automatically parse them neatly in separate fields. I've attempted it many times but I just don't get it.
Really good video! Thank you for the advice! I've ran into all of these at one point! I'm interested to know why you didn't mention Embedded Packet Capture on a switch? 5:35
Hey Ryan! Honestly I just don't use embedded packet capture as often as I do SPANs and TAPs. For sure it is another method though. Since it gives the switch more work to do in an already "slow" or "problem" environment, I would probably only recommend it as a last option if the others are not available.
i think most important one is using capture filters
it will eliminate unrelated traffic
Yes! They can really help. As long as you know exactly what you are filtering for.
Hi Chris, do you have video deep analysis about UDP ? i see most of video deep analysis is related with TCP in your channel. I would like to learn how to analyze 'Voice Call over Whatsapp' to investigate voice quality...thanks in advance...
It's on my punch list for sure! Thanks for the comment.
@@ChrisGreer great..i will be waiting for that :)
Hey I'm connected to the network but I only get information on my device I get no traffic from my phone that is connected to the same wifi pls help me
Very nicely done!
What does MPLS traffic/tagging look like in wireshark?
i cant understand what exactly what we are chasing...
i dont trust wireshark now days when i insatelled it a while back and my laptop started acting strange 3 time this has happened
Stuff they don't teach when studying for the CCNA! 😂
I totally understand!
The video stopped, loading, not working. Infected?
!!!!!
sir!!! can we see the process id created while connecting with http, throught wireshark. let me know if it can be done. and please provide step by step guide to filter process id that are created in wireshark.
Hey! Yes - arg I need to get a video together about that. Thanks for the comment!
Great stuff
Thank you!
