Info

Accessing the Omneon MediaGrid One ACE is mapped for the owner permission. If the owner belongs to more than one group, the group at the top of the list is picked up and converted to owner group permission. The other user permission is mapped to the everyone group including the owner. The default Omneon MediaGrid ACL is all access allowed. A newly created file or directory inherits the ACL from its parent directory. There can be multiple mounts to Omneon MediaGrid. The owner of the file/directory is the user who specified the Omneon MediaGrid mount command. This user is not necessarily the user who logged on to the Linux workstation. The user is the local mount’s user if the FSD is used. If CIFS, NFS, or FTP is used, the user is the user who mounted the ContentBridge. Omneon MediaGrid handles permission enforcement. File/directory permission can be changed using the standard Linux chmod command. A changed permission affects three Omneon MediaGrid entries: owner, first group to which the owner belongs, and the everyone group. NOTE: The user and group name are incorrect when using the ls -l command because the user and group IDs are not set by the FSD. Managing File and Directory Permissions The Omneon MediaGrid FSDs for Windows and Linux support reading and changing file permissions on the Omneon MediaGrid file system. Windows and Linux have different file permission models. It is recommended that only one operating system be used to manage file permissions to avoid confusing settings. This section provides an overview of file permissions for both operating systems. See the documentation accompanying your operating system for more specific information on managing file permissions. NOTE: The client computer must be logged in to the Omneon MediaGrid file system to manage file permissions. Viewing File and Directory Permissions on Windows To view file and directory permissions: 1. Right-click My Computer and then select Explore. 2. Right-click the Omneon MediaGrid file system or directory within the file system and then select Properties. The Properties dialog box displays. 168 Installation and Configuration Guide
Figure 58. MyDir Properties Accessing the Omneon MediaGrid 3. Click the MediaGrid tab, which shows the following information, depending on what is selected: • The version of the Omneon MediaGrid file system driver installed. • The Path of the selected file or directory. • The ReadAhead value. • The current Replication factor. Type a new number and then click the Change button to apply a new number. • The Quota setting (if a directory is selected). • The Reservation setting (if a directory is selected). Changing Security Permissions on Windows Omneon MediaGrid allows you to set user- and group-level security for the various Omneon MediaGrid files and directories by using Access Control Lists (ACLs). The Omneon MediaGrid system receives ACLs when it joins directory services. These ACLs are stored on the ContentDirectors. NOTE: File permissions can also be set using the Omneon ContentManager application. See the Omneon ContentManager User’s Guide for more information.
