Tom recently did an update to our CloudShark plug-in for Wireshark to give it a bit of a dusting and put on some new polish. We’ve made it a bit easier for Windows users to install, and makes sure you get your API token in the configuration properly.
Installing the Wireshark plug-in in Windows 10 To recap on installing in Windows, it goes like this:
Download the plug-in from github.
Wireless networks are the most ubiquitous type of network modern IT departments need to deal with. There are many tools for troubleshooting them, but what happens when you need to go to the packet level? How do you capture at the point you need, and how do you get those captures to a place you can analyze them?
Join the CloudShark team as we show you:
Performing packet captures on Meraki and OpenWRT based devices, and using their native CloudShark support to upload to a CloudShark Appliance Organizing those captures in CloudShark Collaborating using CloudShark’s web-based analysis environment Watch the video.
You look at packets every day to do your job. Isn’t it time to apply the concepts that make all of our modern apps - portability, organization, and collaboration - to packet analysis?
If you are new to CloudShark Appliance or diving into our 30-day free trial, or even just curious about how you can organize, analyze, and collaborate on packet captures in your browser, please join the CloudShark support team on Thursday, September 25, 2014 as we show you the basics:
The pcap capture file format has been the universal packet capture format since the early days of computer networking. Almost all capture tools support the pcap format. And while vendors have created new formats over the years, most tools support conversion into the pcap format.
While pcap continues to be used today, it does have some limitations that make other formats more attractive. A new format called “pcapng” has been under development for a number of years.
CloudShark 1.9 includes the ability to visualize RTP streams and play them back if they contain audio. For SIP calls, CloudShark will automatically decode the conversation as an RTP stream. However, for other protocols RTP will generally use a random port - not immediately apparent to CloudShark.
You can easily work around this using CloudShark’s “decode as” feature, which tells CloudShark to treat data on a given port as a particular protocol of your choice.
This challenge is now finished! Read the solution below or scroll down to try the challenge for yourself! The Solution CloudShark lets you embed your filters directly in the URL. When we view this packet capture file, we are already brought to the view we want to see: in this case, only DNS and ICMP messages.
Why is that? The problem we’re looking to illustrate happens to be an ICMP packet that is tied to a particular DNS response.
Wish you had a place to put all of your captures? Wish you could do analysis on an iPad? If you missed us at Sharkfest ‘12, join the CloudShark team as we show you how our lua plug-into the Wireshark interface lets you easily upload captures to CloudShark, where you can instantly secure, share, and analyze your captures anywhere, at any time, on any device.

The great thing about CloudShark’s capture decode is that it supports all of the standard Wireshark display filters. You may know the common ones, such as searching on ip address or tcp port, or even protocol; but did you know you can search for any ASCII or Hex values in any field throughout the capture?
It’s true. The “frame contains” filter will let you pick out only those packets that contain a sequence of any ASCII or Hex value that you specify.
