I love your videos. Wireshark has always been an overwhelming application. It can feel like you are drinking from a. firehose and there is so much chatter. After just watching a couple videos it has already boosted my confidence and given me some skills to filter out the noise to find the info I want. I will continue on with the rest and i am also working through some of the Pluralsight classes you authored. The best part of these youtube videos, at least for me, is it's broken up into small bite size tasks. If i want to know how to do a particular task. Like this video i can find the one I want and quickly figure out how to get what knowledge I need and want.

Am i wrong saying i can just have a column for 'delta time displayed' and then do 'follow tcp stream' to achieve the same thing?
@ChrisGreer
@ChrisGreer 2 жыл бұрын
You could, but when you are working with a multi-threaded application or several TCP connections in parallel, it's harder to find the delays because you have to filter the streams one at a time. A TCP Delta column lets you see the delays in context, without needed to filter the connections one at a time. So in short, in a pcap that only has one or two connections - the delta time displayed would be ok with a connection filter. But any more than that you can speed your analysis with a TCP delta column.

I think you are referring to user ID's and passwords? Generally no since most of that is encrypted, unless we have stored the session keys and they are exchanged in clear text. Protocols like telnet and FTP still allow you to see them though.

@sujitharajan6468 0 seconds ago Hi chris, thank you for this amazon work. At @3:42 around when you add TCP delta and sort you see 19 sec delay packets. You said that this is in consideration with the above TCP packet whereas the before sort gave a 1 second delta. How is it that if two packets has a 19 second delay between them that is not shown while sorting time delta ?
