    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.

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

    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.

    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)?

    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 ..

    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?

    • @jasperbongertz4866
      @jasperbongertz4866 ปีที่แล้ว +1

      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
      @mwiza ปีที่แล้ว

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

    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.
