To effectively troubleshoot network issues using Wireshark during the SF22US conference, you should start by understanding your network layout and capturing traffic with a broad scope. Apply filters to narrow down to specific issues and capture traffic at strategic points. Familiarize yourself with key protocols like TCP, HTTP, and DNS. This process will help you analyze network traffic, identify problems, and troubleshoot effectively.
I would like to know if it is possible to connect an Ethernet cable to my access point and in my notebook and configure Wireshark to see all the wireless traffic generated on the access point. It is possible to configure Wireshark to see wireless traffic on the Access Point over the ethernet cable. Thanks a lot for the help!
So the dissallowed ip range, on that subnet, no IP address were allowed .... /24 tell everything .. Unless you whitelisting the client IP address .. am i right ? Lets say i want to make a whitelisting option, we should dissallowed by /24, and allow just 1 IP (must be static), from the client .. And the topology is Internal Network for the VM's ... right ? and Wireshark is good for digging network artifact, but overall your video is clearly understandable ... thank you sir ..
Hello Sir, how are you arriving at that no.of routers. For example, when i ping my gateway router, i 'm getting a TTL of 113. How do i calculate the no.of hops(routers)?
How do you set up a live capture 4G / 5G call processor with Wireshark? I know how to capture pcap trace file, but that can only be done from the EPC or 5G Core.
I look at the "Usual Suspects" of starting TTLs: 64, 128, 255. 64 is too low, so we can rule that one out. 255 is unlikely because that would mean we'd have 43 hops and it's rare to see any hop count above 23, and more so above 35. So we can assume 128 is the starting TTL, which would mean its 16 hops (128 minus 112) , which is very reasonable.
Thank you for this video. I shared it with a few friends. They were so excited.. You are missing out on potential viewers by not using a service such as *promo sm*!!!
This is the best tutorial I have found for Wireshark. Not only you included some fundamental, your way of explaining the topic is so nice.
One of the best video on basic network troubleshooting.
Thanks for sharing for free 🙏🙏🙏
Thanks for watching!
What a fantastic session, I learned a lot of new stuff. Thanks for sharing with us.
Glad you enjoyed, stay tuned for more!
Did not see the session in person but it wound up on my recommended. Great video and very informative.
Thanks for tuning in, we'll be doing more live classes in 2023!
Thank you, this was easy for me to follow and understand.
Firewalls, load balancers, and other network equipment can reduce TTL without being actual hops in the path. Traceroute will do a better job counting
Well done. Please do more
Excellent session! Thank you so much Jasper!
Thanks for tuning in!
Awesome video! It got me interested in wireshark, thank you!
Glad to hear it!
Well done. Clear and concise.
Pure gold.
Very Informative Session
Many thanks for such consolidated one
like the ways he explained it all. Thank you.
Thanks for watching!
Love it. Thanks for sharing
Great video, thanks for sharing 👍👍
Good job, thanks!
very good video
Thanks Rose!
very nice tutorial.
I feel like hearing Arnold Schwarzenegger :-)

I'll be back! :)
Yep, the Terminator are trying to troubleshoot tge Skynet Server network ..

More real scenarios would be nice
@@ThePumbaadk there are a bunch more scenarios in our past videos if you want to check them out!
Great content, hope to hear more from him.
There will definitely be more!

useful session. can we expect another session from Jasper regarding Throughput issues :)
Jasper will definitely have more sessions at upcoming 2023 SharkFests! We'll let him know that throughput issues were requested.
@@WireSharkFest Hi Did jasper uploaded this throughput issues?
@@JanezGamingNo, I haven't presented that kind of talk yet. But I'll keep it in mind ;)

In the case of Google's TTL of 112, How do you find out the number of hops? What formula do you use to find the number of hops?

So we can assume 128 is the starting TTL, which would mean its 16 hops (128 minus 112) , which is very reasonable.
It started at 128 and drops by 1 for every hop. Therefore 128 - 112 gives you 16 (hops)
Why didn't you telnet the application server port simple
