Intro to Wireshark: Packet Capture and Protocol Analysis

Veteran IT guy Don Crawley from soundtraining.net shows how to use Wireshark to capture IP packets and analyze their content, including cracking a Telnet password. More videos, how-to guides, and upcoming seminar information at http://www.soundtraining.net/

"Overwhelming" is an understatement. In my opinion, having to resort to a packet stream to troubleshoot and understand what's happening is impractical and inefficient.

@schratboy How do you prefer to do it?

Is there anyway to configure wire to see all the wireless cards on a specific wireless network not just the one the computer you are on is operating?

[doncrawley]

Wireshark looks at traffic on the network, not at hardware. Each packet, however, will show both its source and destination, so you can tell which network card (wired or wireless) is generating the packet.

[doncrawley]

Wireshark will show you the protocols in use on the network. You would have to know the protocols that are used by the games in question. There may be a way to do it, but I'm not aware of a way to identify particular game traffic with Wireshark. (A Cisco router or switch running NBAR can do that. Perhaps a subject for a future video.)

for example I want to know how much of lenght can a protocol recive how wold I do that?

[yksnimus]

how do I get packets sent only to youtube, and received only from youtube, i.e.??

I need to check some streamming protocols, and have no clue how to analyse that with wireshark..

@sundancekid122 .......... PUT A WIRELESS CARD IN YOUR PC

@Nkatsikanis use telnet lol.. that is what this is about.
