Chris, you are just awesome! Do you have whole your courses available somewhere? Like you mentioned you run a few days classes. I am very keen to watch those recorded - something like what INE (and others) does.
Hello Alexander - very happy to hear that the videos are helping you. I have an on-demand training available on Udemy. TCP/IP Deep Dive with Wireshark - bit.ly/udemywireshark Check it out! It's got a ton of hands-on labs, assignments, and ways to practice on your own. I hope you like it.
oh gosh this is wonderful. clear out many things. working in ISP receiving client complaints how their replication cant be done cause they cant see full throughput. i wish i can send them this video to learn how network work and before blaming their ISP they need to check wats going on with their application.
Superb explanation ! Thank You Chris. As a TAC Escalation engineer I find this very useful. Will help a lot of folks who want to understand how TCP works.
Im not a native english and im not even so good in english but all these hard stuff with your teaching style, is so understandable. Thanks and i wish best for you.
such a fantastic teacher and such insights into the TCP packets. I watched a 5 hour course on Wireshark from another teacher and watching this video I realized I am finally learning what the 3 way handshake is. This teacher should educate all network administrators and cyber security personnel.
I hope you know you're awesome !! The best thing is how you put 'air' into explanations and let the audience take notice of subtle things, ruminate, analyze and really understand. You have covered so many topics in this single session and made sure that everyone remembers/ retains 90% of those (I'm an app-guy and others would retain more than me). Amazing stuff !!
You are one hell of a expert Sir! I learned what I could not understand even in my years of networking career and in college degree. Thanks very much, appreciated!!!!!!
I guess you don't know how Noble work you are doing .... I really appreciate the effort you put in to learn weeds of TCP and importantly sharing your knowledge..... God Bless .Keep going
Chris Super explanation of TCP. More window Size to you..... I have seen lot of videos for tcp but this one contains all of it most the part i would recommend everyone to watch this video instead of shuffling through the youtube bits and bytes of other tcp video
Fantastic Chris! Your wait for the packet from layer 7 (1:12:00) was hilarious! You have actually inspired me to learn more on TCP. Thanks for the video.
Your courses on plural sight are the best. I've done other tutors' courses on plural sight and linked in learning which left me a bit confused since they hit the surface without much explanation. I just finished your "foundational TCP analysis with wireshark" course which is clear and the orderly step by step layout makes it easy to understand. Great job👌👌
this was a brilliant hands-on example Chris. In additional to clearly explain how TCP works and why handshakes are always so important, you have humoursly also explained why application guys and network guys keep bickering over latency issues. I am from application team and this video has enhanced my troubleshooting skills. Thank you so much for posting this!
Hi Chris, great intro into TCP, I'll recommend it to anyone who asks me about TCP beginner talks ;-) But I think there's a small error at 1:01:17 - missing SACK options does not mean there are no fast retransmissions possible. The triple dup ack mechanism works without SACK, but it may lead to full retransmits from the gap. There are three flavors of retransmissions: time out based, fast retransmission triggered by triple duplicate ack, and SACK (which in turn doesn't even need a triple duplicate ack to signal loss)
Thanks for the comment Jasper - I hadn't seen a stack not have the option but still do fast retrans yet. But hey if it's out there I want to be correct about it!
Excellently explained, I know nothing about this but after 1h17mins I can start to see a little of what it’s all about looking forward to the rest of the series
First I thought "Over an hour, that's long...". Now I think "Could have been longer!!!" :-) :-) :-) Awesome presentation. Motivates to dig in! Many thanks!!! :-)
Im in the first few hours of learning to how to become a pen tester. If im honsest, this tcp thing looks relatively easy. I'm mostly worried about the command's i have to remember. A whole new language. Including phyton. But this is super interesting. Do you have tips and tricks, I've get what ipv4/ipv6, subnetting what a /20 a /24 network is. And how and why it's different, and what routing is, what a gre and ipsec tunnels is. What an handshake is, and what the window sizes and the multiplier is, The package size. I'm curious how to continue. Looking forward to learn way more about networking, testing kali, linux, understanding and writing code, discovering that I don't understand anything of this. And learning to understand. Love this journey so far... Thank you for this video and the collaborations you did with david bombal, and many others... Cheers!
STRAIGHT FACTS at 21:30 - 21:40. I am nothing special when it comes to network security but EVERYONE in my workplace wants the scripts I made for automating network packet inspection and other tasks. One day I caved and said fine use this, 45 minutes later. I get a teams message "hey can you explain your script? i don't understand what it's looking for, how is that relevant?" All i wrote was "I don't have the time to explain it." It's like those people who get stuck on the "how to get started in (insert topic) videos" and tutorial videos. At some point you have to become curious yourself and dive headfirst.
@@ChrisGreer Thanks for the response, you have amazing straight to the point content. I've recently been trying to make a department switch and your videos on TCP have helped me out substantially.
Thank you Chris for this video, you're a great teacher. Your explanation of waiting on Layer 7 traffic to fall down to Layer 4 on the server side was hilarious. 😂
Hi Chris, thanks foe the nice and informative video, watched it couple of times and using it as a reference. I have a question which I couldn't find any answer for that. What does "windows scaling factor -1 [unknown] means and is it a problem ? Thanks in advance.
@1:10:54 you said after http get from client . server sent ACK only acknwldg previous sent data but not sending any other data, that is perfectly fine. But i have one doubt. you said if that ack is not received to client then it will re-transmit. i think client will not re-transmit. TCP-keep alive message should go in that case.
I entitle my delta column with a Δ . Like the greek delta Δ. Yay unicode! But if that's too uppercase for you then δ also will work. I just figured out in the midst of a 35 hour long packathon of looking at frames, with my vision going blurry and my mind actually starting to think Cisco is a real company I'll be able to make out Δ and what it stands for a little easier.
[placeholder for screenshot URL that is coming up] About half an hour later I came up with a much better approach it seems. Just take the nerd fonts I already use for powerline, airline, sofaline, toiletline, lineline and use some of its extra icons and then install it as a font in Wireshakr. The delta is just much crispier. Oh and while I was at it I pulled a clock and replace time title with that too. I am currently brainstorming with chatgpt as to how source and destination can be represented by the icons. Otherwise great conversation, dude! I'm a red teamer and the way you talk about TCP signifies that you have such extreme levels of expertise that you are like fluent in it. I'm probably gonna pull out my fountain pen anda take some notes tbh ans so far that's only been reserved for MIT OpenCourseWare stuff (like csail from original HP recording). I just learned more about TCP in three bours binge-watching your videos than in the last like 10 years I think.
what is the relation between window size and mss? i.e. if we have a window size of 65535 and a capacity of 1460mss, does it mean we can receive almost 45 tcp segments with 1460 bytes in payload each in a row?
@Chris you are amazing man! from your body language I feel you dive inside the wire a swift through these packet! I love it. quick question, minute 48:53 can you please show me the math behind how TTL 111 translate to 17 routers (n00be asking)
Thanks for the feedback! Yeah so most devices start with IP TTL's of 64, 128, or 255. So when I see 111, it likely started at 128 and traveled through 17 routing devices along its way to me.
Hi Chris, Great content and excellent way of teaching the basic stuff. Liked it alot, i have a question if anyone can help me out here. 1. There is URG flag in TCP control bits and we see urgent pointer in Wireshark captures, whats the major difference in both, or in other words what is the significance of both. Really appreciate if you can help me with this question...
Sure I would be happy to help you with that one. So TCP doesn't know anything about when data from an application "starts" or "ends". It's just a stream of data, and TCP's job is reliably getting it from one endpoint to another. When the URG flag is used in conjunction with the Urgent pointer, this is a way for TCP to know that a certain byte (or bytes) of data are important and need to be urgently processed upon arrival. It's a similar idea to the PSH bit. But with that bit the whole segment is considered important and immediately sent to the application upon receipt. The Urgent flag just allows us to point to a specific data point within the segment that is important. In practice, you don't see this terribly often. But I'm sure it's out there lurking around somewhere.
@@ChrisGreer thanks a tonn for this valuable input and clearing my confusion on this. I am already following your wireshark series since recently started analysing packets.

@Chris i have one quick question what is idle or best time format setting you suggested or best to use in packet analysis. since beginning or capture or previous capture or displayed options. can you please give a detailed analysis on this
Hi Chris, nowadays i am watching lot of videos on wireshark. but your approach of understanding is unique. I really appreciate if you could please assist me on below. I was reported issue, where application team was facing duplicate transaction issue. and i was contacted to see if network is causing any issue. 4 servers are involved in this and i have taken wireshark capture on all 4 servers. but it is using SSL protocol which is encrypted. so as per my thinking i think we cannot come to know if duplication is happening by looking to TCP\IP packet only. could you please suggest me if it is possible.
