The Settings page can be accessed by clicking Settings in the Administration menu. This page allows different system wide settings to be modified, including:
- System Name: the system name is initially inherited from the Linux hostname. The system name is useful for uniquely identifying a CloudShark system, and is displayed in the top left corner of the user interface and in the browser title bar.
- Guest Access: is disabled by default. A guest is a visitor without a CloudShark user account. With guest access disabled, all users must log in to view or upload capture files. When guest access is enabled, guests are allowed to view and optionally upload capture files based on the Guest Upload option.
- Public Files: Capture files and tags are indexed by CloudShark in the capture index page for all users by default. Setting this value to Hide public captures will hide captures that are not owned by the user or their group. This allows a CloudShark administrator to have unrelated groups of users without exposing their capture files to each other. Set to Hide, capture files from unrelated users and groups will not be listed in the capture index. Attention: A public file, that is one that does not require CloudShark authentication to view, is still viewable when the URL is known. This setting is only for changing whether or not users can see each others files in the index.
- Guest Upload: by default guests are only allowed to view capture files that have been shared by other CloudShark users. In this mode guests are not allowed to upload capture files. When enabled guests are allowed to upload capture files in addition to viewing capture files that have been shared by CloudShark users.
- Maximum File Size: by default CloudShark will allow captures up to 2 GB in size to be uploaded and viewed. This file size limit may effect performance. Please see our system requirements for more information on tuning this setting based on your system.
- Download Original: by default CloudShark users are able to download the original source capture files directly from the decoder window. In certain situations it may be desirable to prevent users from downloading the original source capture files. This setting globally enables or disables original source file download functionality with CloudShark.
- Blocked Types: You can specify file types that you do not wish users to upload. This is convenient in the scenario where CloudShark is on a public network. Frame based audio, image, and movie files such as MP3, JPEG, and MPEG are supported for decoding by CloudShark and so are valid files to upload. Because of the “Download Original” features of CloudShark, this can allow it to be used as a repository for sharing these files. With this Blocked Types option, you can control the type of files CloudShark will accept in the manner that best suits your needs. You can learn the file type CloudShark expects by using the ‘capinfos’ tool on a file you wish to block and inspecting the “File type” output.
