New Features and Highlights

Migration to CentOS / RHEL 6.x base operating system

CloudShark 1.8 now requires a 64 bit version CentOS or RedHat Enterprise Linux (RHEL) 6, both of which are popular Linux distributions with a focus on security and long-term stability. CloudShark 1.8 does not support Ubuntu, and existing systems running version 1.7 or earlier will have to migrate to a CentOS or RHEL system prior to installing CloudShark 1.8. Please see our migration instructions or contact

CloudShark is compatible with CentOS or RHEL versions 6.0 through at least 6.4, and all installation types, ie minimal install, full desktop install, etc.. We recommend a minimal install of the latest available CentOS or RHEL 6.x release and any available security updates. To update an installed CentOS or RHEL system, run the command su; yum upgrade.

For more information on CentOS or RHEL, or to obtain installation media and instructions, please visit the CentOS or RHEL websites:


New CloudShark Lounge

CloudShark users migrating to version 1.8 will be set up with accounts on the new CloudShark Lounge. The CloudShark Lounge is a fully automated user portal for CloudShark 1.8 that makes it easy for users to activate and manage their CloudShark licenses and download and install new releases. If you are interested in installing CloudShark 1.8 and would like an account on the CloudShark Lounge, please contact

Streamlined upgrade and installation procedure

CloudShark 1.8 is installed by running a script available to registered users in the CloudShark Lounge. This script configures the operating system with a CloudShark repository and a CloudShark specific system administrator interface (the ‘admin interface’). The admin interface connects to the CloudShark repository and Lounge to register and license the system. Following the one-time registration and licensing step, the core CloudShark software is installed. At this point the CloudShark appliance is fully activated and ready to use.

Support for spurious tcp retransmissions display filter

Patched tshark to support a new display filter, tcp.analysis.spurious_retransmission, for viewing spurious tcp restransmissions.
