Let's keep learning more about Wireshark in this tutorial. Filtering traffic with Wireshark is important for quickly isolating specific packets and dig down to the ones that matter. They are very important to learn for troubleshooting and traffic forensics.
The problem is that filters can be hard to learn and remember, especially when you are first getting started with Wireshark. In this video we will look at capture vs display filters, how they work, and some common filters we can use to isolate traffic.

Version 4.0.4 Filtering for a text string works ony if you put Google into quotes: frame matches "google"

@ChrisGreer Жыл бұрын

I know, love how that was changed in 4.0! Used to be that either way worked but now it's only the quotes.

As a developer, I’d love to learn Wireshark mostly for capturing HTTP/HTTPS between my development machine and various APIs. I ended up just using Fiddler because Wireshark seemed much harder to figure out. The bar to entry seemed too high for something simple. Your videos might help me finally commit to learning Wireshark though!

Great series so far. Hoping you will go as far as looking at protocols in wireshark such as smb, nfs, dns, ldap. Looking at the various values, what they mean and troubleshooting some common issues such as poor copy performance, ntlm/Kerberos authentication issues etc. Not asking for too much eh 😉. I ask because i KNOW you are capable of explaining it well!

@ChrisGreer 3 жыл бұрын

Hey thank you for the comment - this series will focus more on the analyzer itself than the protocols. But, I will keep making content around different troubleshooting scenarios!

Hi Chris, Can you please help in understanding different flags that we see in capture like the one below: 10.236.28.5.63737 > 40.79.154.87.443: Flags [.] --> What this . [dot] signifies inside brackets. Also, if you share some light on how to check DNS related issues via capture.

Is a pc using wireshark able to capture all traffic or just traffic specifically with that pc?

@Ishvires Жыл бұрын

Is it possible to have a filter for such scenario: imagine you are in a voice call and you have voice packets going in and out + you have some other packets because your other software installed using network and here is the thing: is it possible to build a filter which will ignore everything what is happening right now and will start showing packets if something new appears from next moment? In other words - ignore packets from every connection and just show packets from new connections? Obviously it is possible to build this filter manually, but this is quite labor intensive, but maybe you know a way/trick which could solve this with few mouse clicks?

11:25 Wireshark has continued to evolve, frame contains google as in the given example doesn't word anymore, you have to put quotas as in frame contains "google".

@washyourhands907 Жыл бұрын

Hey Chris, this series is amazing. However, some of these commands are out of date. I just tried them in wireshark and they didn't work for me. Ex. "frame contains/matches google" didn't work and searching by port number. The santax changed a bit for searching by port number, but I couldn't find out how to do the first one I talked about. Do you have any updated commands for these please?

Is string 'contains' not supported in WIreshark 4.0.5 ?

@ChrisGreer Жыл бұрын

It is, but you have to wrap the string in quotes. frame contains “Facebook”

@user-rv6gl5oo4t 6 ай бұрын

Hello @Chris. I tried but tcp.port in {80 443 8080} shows incorrect syntax with "red" in the display filter field. However, tcp.port in {80, 443, 8080} is "green" and gives same filter result as tcp.port == 80 || tcp.port == 443 || tcp.port == 8080. Currently using Wireshark Version 4.2.0 (v4.2.0-0-g54eedfc63953) on WIndows 11.

Hey thanks for the comment. You are correct, in pre-4.0, the filter would work without commas separating the values between the curly braces. Now from 4.0 and newer, we need the commas. Unfortunately I can't update it in this video, but my more recent content reflects this change.

Hi there if I type in "frame contains google" or "frame matches Google" it just get red and I can not apply the filter. Not sure for what reason this does not work 🤷.

No you are now correct in that syntax. Pre-version 4.0, you did not need the quotation marks. Now 4.0 requires them. Haven't gotten around to re-shooting this video yet!

Hi, thanks for video, is there a command to group lines by same message so it show a message just once on multiple requests? Something like group by dns.qry.name

@ChrisGreer Жыл бұрын

I would probably do that with tshark. "tshark -r (filename) -T fields -e dns.qry.name | sort | uniq -c" That will extract all the qry names to a list and only show them once.
