Building wireshark display filters11/20/2022 ![]() Notice the URL there too! Exporting filtered packets into a new capture As you can see, the annotation includes a link to the DNS response metrics for the capture. In our example, you probably already saw the annotation we added to one of the DNS responses. Since everything in CloudShark can by built as a URL, this allows you to link to other analysis tool views from the annotations. Links are made by using an closed bracket around the text you want to be the link, immediately followed by an ( open parenthesis and a ) closed parenthesis containing the URL you want to link. ![]() You’ve used an annotation to point something out, but did you know you can embed links in them too? Since the annotations use markdown syntax, you can use the same notation you use on, say,, to create them including adding links. Rather than scrolling through the entire set of packets, we can filter out a range using ‘ frame.number >= 140 & frame.number <=180’.įiltering based on a range of packets Using links embedded in annotations Some of our users get around this by using a filter range based on the packet number. Sometimes CloudShark can be loading a lot of packets, and you want to start somewhere deep in the list. ![]() Filter based on capture number using a range This means whomever you share that link with will see what you see. Notice that the URL includes the filter expression (formatted as a URL). Here’s a capture of one of us browsing We know that’s what we’re looking for, so we use the filter ‘ frame contains cloudshark’, which returns to us only those packets that contain the word ‘cloudshark’ in their payloads. If you know there’s something in the capture you’re looking for immediately, and you want others to see what you’re thinking, you can use the filter ‘frame contains’ to search for a literal string that exists in the capture. Here’s some tricks we use when getting around town in CloudShark. With CloudShark, they present a new opportunity for use when sharing your captures with colleagues in order to both present the view you are looking at, or to help navigate to a section of the capture you want them to see. CloudShark’s display filters are 100% compatible with the Wireshark filters used in packet analysis. ![]()
