Current Access Zone:: From this drop-down list, select the access zone in which you want to manage SMB share settings.

Enable file filters: Click this check box to enable file filtering by file extension. You can deny writes to the share by certain file types, or allow only certain file types to write to the share.

Advanced SMB Share Settings

Click to access a list of advanced SMB share settings relating to permissions, performance and security. We recommend that you do not change any of the default values unless you thoroughly understand the potential effects of those changes.

To change the advanced settings, click Use Custom or Use Default under the appropriate setting title.

Continuous Availability Timeout: Specify the amount of time you want a persistent handle to be retained after a client is disconnected or a server fails. The default is two minutes.

Strict Continuous Availability Lockout: Set to yes to prevent a client from opening a file if another client has an open but disconnected persistent handle for that file. If set to no, OneFS will issue persistent handles, but discards them if any client other than the original opener attempts to open the file. The default is yes.

Create Permission: Sets the default source permissions to apply when a file or directory is created.

Directory Create Mask: Specifies UNIX mode bits that are removed when a directory is created, restricting permissions. Mask bits are applied before mode bits are applied.

Directory Create Mode: Specifies UNIX mode bits that are added when a directory is created, enabling permissions. Mode bits are applied after mask bits are applied.

File Create Mask: Specifies UNIX mode bits that are removed when a file is created, restricting permissions. Mask bits are applied before mode bits are applied.

File Create Mode: Specifies UNIX mode bits that are added when a file is created, enabling permissions. Mode bits are applied after mask bits are applied.

Change Notify: Configures notification of clients when files or directories change, which helps prevent clients from seeing stale content, but requires server resources. The default value is Norecurse.

Oplocks: Indicates whether an opportunistic lock (oplock) request is allowed. An oplock allows clients to provide performance improvements by using locally-cached information. The default is Yes.

Impersonate Guest: Determines guest access to a share. The default is Never.

Impersonate User: Allows all file access to be performed as a specific, fully qualified user name. The default is no value specified.

NTFS ACL: Allows ACLs to be stored and edited from SMB clients. The default is Yes.

Access Based Enumeration: Allows access based enumeration only on the files and folders that the requesting user can access. The default is No.

HOST ACL: The ACL that defines host access. The default is no value specified.
