 Hello, in this video I want to show you how in the new pcapng format used in Wireshark you can annotate your capture file, so add comments. And this video was inspired by a blog post on ISC diary entry by Xavier Mertes. So if you go to Help, Sample Captures, then you go to the Wiki Wireshark with a lot of sample captures, and let me search here for simple HTTP. And this is the one that I'm using here, http.cap. So this is the file, I can select packets, let me select this Get HTTP packet. I right click and I say packet command. And now I can add a command to this packet. And watch here, here with the overview of the protocols. So I say, for example, first download, okay. And then here you can see that the packet command was added here, first download. You can filter on this frame command like this, here and then you have all your packets with comment. So let's add another one, for example, here on this DNS one. Packet command, DNS packet, okay. And now I have a second one. So if I go back to my filter, like this here now I have two packets, and I can also say, for example, contains download, like this. And then I get this packet. Now this command here can also be added as a column because it's a field and you can add it as a column. So I can right click here and say apply as a column. And then here you have a column with comments where you can see all your comments. So these are comments that can be applied at the packet level. But in that new pick up and g format, there's also the possibility to add a global comment for the complete file. And that you do by going to statistics, capture file properties. And then here you can add your comment. Global comment like this, save it and close it like this. Now it's important to understand that comments here are only supported in the pick up and g format. So if I try to save this here, this will give me a warning. Because if I save it in this format, in the cap format, I will lose the comments. So I have to save it in a pick up and g format to persist the comments.
