01 - Network Troubleshooting from Scratch | Learn Wireshark @ SF22US

[@bsh7390]

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.

[@saurabh9m]

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.

[@WireSharkFest]

Glad you enjoyed, stay tuned for more!

[@iSirLincoln]

Did not see the session in person but it wound up on my recommended. Great video and very informative.

[@WireSharkFest]

Thanks for tuning in, we'll be doing more live classes in 2023!

[@hh3224]

Firewalls, load balancers, and other network equipment can reduce TTL without being actual hops in the path. Traceroute will do a better job counting

[@harrysearia1784]

Thank you, this was easy for me to follow and understand.

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!

Very Informative Session

[@ChapalPuteh_]

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 ..

very nice tutorial.

[@josephkilonzo5994]

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.

[@tahersadeghi6773]

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?

[@WireSharkFest]

Feel free to ask this question in the Wireshark Discord server, it's much more likely to get a response there! discord.com/invite/ts9GZCjGj5

[@jasperbongertz4866]

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.

[@mwiza]

It started at 128 and drops by 1 for every hop. Therefore 128 - 112 gives you 16 (hops)

[@codydietrich4246]

Thank you sir!

useful session. can we expect another session from Jasper regarding Throughput issues :)

[@ВиталийОвчаренко-и1н]

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.
