Once you begin capturing traffic, Wireshark keeps track of all the connections or streams. Lisa Bock reviews the conversation window, which has many options to view and manipulate the different types of conversations.
- [Instructor] Once you begin capturing traffic,…Wireshark keeps track of all the connections…or streams.…Now, once you have a connection,…your operating system creates a socket,…which is an IP address and a port.…And if we drop down TCP, you can see stream index zero.…Well, now we know there's no field value…called stream index.…It's Wireshark's way of keeping track…of all your connections.…Now, if you wanted to see all your active connections…on a Window machine, we would open a command line…and run Netstat AN.…
Now, once you run that command,…and I'll scroll up,…you'll be able to see all your active connections.…So Wireshark's doing that, as well,…and there's a couple features that we can use…in Wireshark to help us keep track of what's happening…and one of them is Conversations and Endpoints.…In Wireshark, a Conversation is between two Endpoints.…An Endpoint is one side of the Conversation.…To view all the Conversations,…we'll go to Statistics and then Conversations,…but first let me filter,…and I want to prepare as a filter…
