Wireshark 101: Fixing Network Problems with Wireshark, HakTip 134

[@hawaiisidecar]

Very informative channel. The archives of past shows are priceless tutorials.

[@hak5]

Thanks!

[@Kennomie]

I love female tutor teaching IT topics, so cool.

[@RudyAviles]

I agree :)

[@BuickGeek24]

SYN packets are not "synchronize", it's "connection established"

[@crc6896]

uhh, it does synchronize sequences though? The three-way handshake isn't hard to understand bruh

Traceroute is a network diagnostic tool used to track in real-time the pathway taken by a packet on an IP network from source to destination, reporting the IP addresses of all the routers it pinged in between.

[@PlexusMC]

You're wrong and right, but dumb statement

[@Lucas-md8gg]

Yeah, basically both client and server synchronizes their sequence numbers, the server sends a phantom byte to the client meaning it has received the client's sequence number

hey, I know this is a 7 year old video, but I have a really weird issue. I am unable to use internet [browser to be precise], while using Wireshark [running the scan]. This is super freaking weird, because I wanted to inspect packets from a specific website. So I started a scan, clicked on the link -but the site would not load. I would then stop the scan, click that same link - and the site would load.... Any ideas?

[@TheNomoi]

why not just traceroute?

​@@thuggy67 This is overcomplicated talk for traceroute only identifies IP Failure between the routes Seems like it was just copied from the result of searching "what is traceroute" There could be more issues, IP addresses are only layer 3, though there can be a failure on another of the 7 In the case it's a DNS issue, traceroute will still show its working. Think of how the website works You have a server it's hosted on an application the website is running on and the website itself traceroute or even ping will just show the server as being up, not necessarily the website this video didn't explain much, the server could also block ping requests (which most of them do for security)

After uninstalling wireshark, some IP camera are unable to reconnect and unable to add to camera utility, as every information is correct

[@pokerrus78]

Hello Shannon, I love the video and quick tutorial on wireshark but "IMCP Protocol" is a bit redundant, don't you think? Do you also say "ATM machine"?

[@PlexusMC]

Sometimes i get annoyed at this but everyone does it, even me. PC Computer IP Protocol SSD Drive DNS Server

[@DeveloperTrance]

Such a smile!

[@train4905]

Awsome😊

[@arunoct22]

what is malformed packet? how to resolve it?

Dear Shannon Please get rid of windows for your own security and privacy

[@hak5]

I use several different operating systems. My main reason for using this PC is because of the HDMI output for our HD cameras. Much better for viewing small text on my screen. The reason I haven't switched to Linux (instead I just use a VMWare), is because this hardware is borrowed, it isn't mine. I don't want to deal with dual-booting or reinstalling Windows once I have to give it back.

[@DS-ce4um]

Crestoify I think it's funny that people think Windows is the only OS that can be hacked. They all can. Almost every Linux CVE is a 7.5 and above. The Ghost vulnerability came out right before this user posted. MACs currently have a vulnerability that can be exploited through the browser and reflash the BIOS, gaining persistence even after replacing the HD! But yeah, keep hating on Windows.

[@Fermion.]

I always ask people like that to explain why, starting from the kernel level. That's never failed to shut them up. Curious techies will actually use it as a learning experience, whereas noobs will still try to parrot the generic "Windowz suxx lolz" mantra.

[@PlexusMC]

It's what works best for the person, most are fine and better off with windows. Stop being the guy in the corner of the street screaming the world is going to end

Battery levels low on the borrowed hardware
