- Where do we capture network traffic and how? In this lesson we will look into where we should place Wireshark to get the best vantage point in our packet captures. Client side? Server side? or both?

Where can we get a t-shirt like that ?
So crazy you ask... I was literally just thinking... Should I set up my RUclips shirt store so the good packet people can buy a Packet Head shirt?? What do you guys think?
Ok guys - I just got the merch store going - go get that Packet Head shirt! Links below video description.
@@ChrisGreer Cool
@@ChrisGreer Are you still selling these shirts? I can't see the link you are talking about?
I'm a newbie, your videos help me so much. Thanks for all.
Thanks for valuable information, looking forward to next lesson
Thanks Ege!
May I also point out that many modern network devices can do embedded packet captures. You basically filter on direction, interface, and what you would like to match for example, with an access list. it adds a buffer of capture packets, which you can view a summary or export to a PCAP.
Perfect explanation. Easy to understand 😀
Thanks for commenting!
Thank you a lot!
your videos are quality

Is Wireshark capable of capturing 10gig interfaces? Im able to capture on the switchport connecting to the server but its 10g and the capture is blank when i open it (also for 10g AP switch interfaces)? Also, Im hoping in a future lesson to see you dissect CAPWAP tunnel data, seems to be alot more in these packets that go to APs interfaces. Thanks!
Chris - Great to see you online, fantastic information, I will be watching your other videos soon. It has been a long time since I used wireshark. Are going to cover other interfaces besides ethernet?
Hey - thanks for the comment. Probably not just because most of the time, people are using Ethernet interfaces to capture, or wifi. So I’d probably do some Wifi content if anything.
Man I need a private lessons of that man there!
That can happen! Check out my course at bit.ly/virtualwireshark
Hey Chris can you make a video for wireless clients
I’m tshooting issue of mobile forklifts loosing wireless connection with meraki access points
Nice explanation. I have a question in my case the wireshark is only capturing my local machine. For other machines, it hardly captures the MDNS packets. Please help me out?
Thank you for this Video. Do you have any video, demonstrating the use of taps? Also, is there any model of tap you would recommend for gigabit ethernet home network(not too expensive) ?
Hi Vyas, not yet, but that is a great idea. I really like the guys at Profitap.com Good people and good product, which are my two requirements when looking for gear.
@@ChrisGreer Thank you for the suggestion. I visited their website and my initial thought was it would be very expensive! I'll connect with them and check.
What I've been trying to figure out is how to use the remote capture feature!
That's a great idea for a video. Thank you!
can u tell me what is tap & span? u didn't mention these in your previous videos!
What are TAPs and SPAN ports. Kinda followed you about placement of capture until those two terms came up.
By network analyzer, are you referring to a physical tool ?
great videos
Glad you like them!
hi Chris. is there any way to change the captured packets IP addresses so that i can hide my internal addressing schema? or change any sensitive data in packet details (like username...)
yes there is - you can use a utility called Trace Wrangler - written by my friend Jasper. It is designed to do exactly what you are looking to do. www.tracewrangler.com/
How do you typically capture the server side when its a VMware environment or cloud in a production environment? Do packet brokers help in a data center? Thanks!
Thanks for the comment Tenz. I rarely merge. I do side by side analysis with two different instances of Wireshark open. In a cloud environment, it all depends. If my customer has the support package, we involve AWS support and enlist their help to get a server-side pcap from the virtual network. If that is not available, sometimes the only choice is to get a dumpcap from the server itself. But that is always plan Z.
Lesson #4 and I still don't understand how to start capturing the traffic. Freshly installed wireshark as a portable. 6 interfaces that definitely not what I need. I just need to capture tcp traffic. And I can't figure out how to do this. But instead, I already set up a policy for files and other not important stuff for me. Could you please explain in you videos what are those interfaces I see (in the menu Capture Options) and how to find the right interface to capture my wi-fi traffic?
What brand of physical tap do you recommend?
profitap.com has some great stuff out there. Let me know if you need tips on which one to look at.
@@ChrisGreer Whats the difference between a $200 tap and a $2000 tap. I know this tap is expensive when they have to quote you for it.
@@ChrisGreer Would love to see a video discussing physical taps and features to look for, and tips.
Thanks....
You bet!
@@ChrisGreer Hi Chris, I would like to start experimenting troubleshooting network issue (ftp/ssh port block fr example) between computers in my house LAN. Install wireshark on my notebook and ftp/ssh server on another pc....can you suggest which tutorial that able to demonstrate this situation to know if the port is block or not yet open or other issues .... so that I can follow it....thank you.
@@joeharyar9873 I don't have a specific video to follow along with for that case, but it should be pretty straightforward. Start wireshark on the client, open the ftp or ssh session to the server, stop wireshark. Look at what is happening over port 20, 21, 22, and any other dynamic port between the client and server. You'll get it!
How do I make my pc a server using wireshark
I am 18, I am following each and every code. It's working. But I have no idea what I am doing.
This is also called port mirroring
I don't understand how I can monitor all traffic out of my home router! I didn't know that we can do it from the outside world.
You know what I do? I bought a little switch from amazon that does port mirroring. It's only like $50 and it lets me capture everything coming and going from my home network. amzn.to/3IHA9Gk
