- Sniffers are certainly nothing new, but can they be used to discover serious misconfigurations in our networks? Yes!
In this episode we look at how to use a sniffer in an easy, repeatable process to find unusual, unauthorized and just plain insecure protocols on our networks quickly and easily! For more information, check out auditcasts.com
Am I the only one noticing the pornography bookmark?
Nice vid though.
+Johannes Meyer It's actually not.. It's a link to a forensic resource for electronic signatures of known illegal pornographic images. It's a dataset that we can use to quickly identify if there's known-bad stuff that would require law enforcement involvement in a case.
You did make me go look at my backups, though! :)
Heh, I actually assumed that's what it was. Is that related to Microsoft's deep packet inspection for child pornogrophy? I remember reading something about that some years ago.
Nope, just part of my forensic business. :)
lol i can see that too
lol That's hilarious!
Great video David, can you recommend other video to learn more about Wireshark. I'am a beginner using Wireshark. Thank you
All I can say is that the methodical approach demonstrated in this video has come in real handy and I can't thank you enough for making this video. Super educational!

so this is to scann your own network? but how do I scan someone else's network?
Thank you for this thoughtful tutorial it does help me to understand wireshark better. You helped to short-cut.. tx again triple thumbsup.
I am a student starting my computer networking degree . Could you please suggest me how can learn more about network security ,pen testing etc .. any certifications?..am from UK
Thank you so much for making our days better with your videos!
Do you know a way to detect network loops easily in a large network? RSTP us enable so helping but I need to find the loop without running around.
Can Wireshark able to trace the machine that trigger viruses or the origin source where /which email of the user come?if not can you provide me how to trace it?
That was a good video on breaking down network traffic to get to a problem.
Can i scan websites from another network.Please help im a noob.
Great video.
I can't seem to find anything to backup that a WINS server will eliminate NBNS broadcast. You got any documentation for that?

from this all, how we will be able to find the vulnerabilities in the network. ??
You can run Wireshark in promiscuous mode, and it will show you all the traffic that is being broadcasted. However you still must have access to the network for this to work (so you can't automatically sniff a secured network) and if you're on a switched network, you'll only receive traffic bound for your system.
Thanks for the help on network vulnerabilities.
Can Wire Shark be configured to trigger event(s) and send notifications (email, text,..) while streaming real time and safe the stream to a hard drive for later analysis?
No. However, you should take a look at Snort. (snort.org) Snort will allow you to do what you are asking.
Hiii, thanks for another great tutorial. Please, I have a question. Does Wireshark capture any wireless traffic such as wifi, or cellular? Thanks in advance!
Juan Juan why did you respond like this???
The reason why I ask is whether it’s even necessary to be able to snif wifi, if you can already sniff packets going through my home router. I guess I need to educate myself more on the whole process. I just want to know if anyone’s using my wifi.
I just want to take this time to thank you for explaining how wiresharke works
When would a span or mirror be necessary?
Very educational. Thank you
As an alternate you might find Fluke Networks ClearSight Analyzer easier to use.
A few years old now but still very relevant. Nicely done.
you mean to set your self as the hdcp server for the host router ? is it like that ?
All I want to know...is where they are!
hey david am trying to sort out my ethical hacking assignment and I am just about to write my recon phase and I am a bit confused on what tool i can use in the recon phase to show a figured example... can you hepl?
What do you mean, "a figured example?" And, generally, I don't do anything with CEH... Like many in the field I don't find CEH particularly useful... GCIH or GPWN, however...
David Hoelzer i mean i would like to use a tool or software in the recon phase and use screenshot figures of the tool to show an example in my assignment.
what i need is what tool would you recommend during passive recon and what do you recommend during active recon. thanks
Well, Wireshark is a great passive recon tool. The classic active recon tool is NMap. Unless you're trying to be creative, why not just use those?
David Hoelzer brilliant idea David thank you.
i can't find any password...can you help me ?
ARP Poison the shit out of that network then
Very good tutorial, thank you for sharing!
Very nice explained. Thanks!
Great video. Many Thanks!!!
Great video! nice voice to listen at.
Thank you for this. Good work, makes Wireshark more valuable.
thanks was a big help
EXCELLENT!!
I'm new to Cain and Abel. Is there a way to brute-force an internet password? Like TH-cam?
Not with cain and abel.
Is there a program we can do that with?
I need to recover a password of mine.
;) If it's your own password use the password recovery features. I'm really not in the habit of helping people break into other people's stuff. :)
I tried all I could but I can't remember any of my passes :(
Good and easy to follow video David.
Good video. Well done!
ty soo much
PRTG is better!
Yeah but... How do I find the vulns?
***** OpenVAS in Kali Linux is free and can use that. If you are planning on scanning someone else's network then get their permission, otherwise it is illegal.
Very good intro vid! #Subbed
:) wrkng !!
Thank you Great Explanation.
