Samba owner file

Real basic needs for now, just sharing files amongst coworkers, but eventually I'm going to need to set up more detailed security privileges Tom and Dick can read and write to everything, Harry can only read, etc..

But for now I just want to get the files up on the server and shared. I've created the users in linux and synched them in Samba via Webmin and then through smbpasswd just to be safe , have poured through hundreds of different sites detailing solutions via permissions, smb. I've tried them all to no avail. Log in as another user and I'm able to see the files but not able to change them or create new ones.

If I change the owner to whatever the user is then that user is able to do as they please, but no one else can in that directory. No other user is able to create anything in a share that is not owned by them. You're all probably pointing at the screen and laughing, but this has me perplexed.

How can I create a share that allows multiple users to copy files to it, modify them, delete them, etc..? I don't want to strip security away entirely but am willing to try anything at this point. The easiest for general sharing is to set file permissions to i. This should change the permissions for the folder and all subdirectories and contained files the '-R' switch. And any new files should inherit those same permissions Note that this is for the Linux users Specifies a UNIX group name that will be assigned as the default primary group for all users connecting to this service.

Specifies a UNIX username that will be assigned as the default user for all users connecting to this service. This is useful for sharing files. Incorrect use can cause security problems. If this parameter is set for a service, then no password is required to connect to the service. Privileges will be those of the guest account. List of users that are given read-only access to a service. Users in this list will not be given write access, no matter what the read-only option is set to.

Refer to the smb. Directory permission-based controls, if misused, can result in considerable difficulty in diagnosing the causes of misconfiguration. Use them sparingly and carefully. By gradually introducing each, one at a time, undesirable side effects may be detected.

In the event of a problem, always comment all of them out and then gradually reintroduce them in a controlled way. Refer to File and Directory Permission Based Controls for information regarding the parameters that may be used to set file and directory permission-based access controls.

See also directory security mask. Enabling this parameter allows a user who has write access to the file to modify the permissions on it. This parameter specifies a set of UNIX-mode bit permissions that will always be set on a file created by Samba. This parameter specifies a set of UNIX-mode bit permissions that will always be set on a directory created by Samba. Prevents clients from seeing the existence of files that cannot be written to.

Unwritable directories are shown as usual. The parameters documented in Other Controls are often used by administrators in ways that create inadvertent barriers to file access.

Such are the consequences of not understanding the full implications of smb. This means that all file name lookup will be done in a case-sensitive manner. Files will be created with the precise file name Samba received from the MS Windows client. Allows specifying a comma-delimited list of directories that the server should always show as empty.

DOS and Windows allow users to change file timestamps if they can write to the file. POSIX semantics prevent this. This option allows DOS and Windows behavior. Oplocks are the way that SMB clients get permission from a server to locally cache file operations. If a server grants an oplock, the client is free to assume that it is the only one accessing the file, and it will aggressively cache file data.

Note: MS Windows Explorer allows override of files marked as hidden so they will still be visible. If this parameter is yes, then users of a service may not create or modify files in the service's directory. This section deals with how to configure Samba per-share access control restrictions.

By default, Samba sets no restrictions on the share itself. This can be an effective way to limit who can connect to a share. In the absence of specific restrictions, the default setting is to allow the global user Everyone - Full Control full control, change and read. At this time Samba does not provide a tool for configuring access control settings on the share itself the only way to create those settings is to use either the NT4 Server Manager or the Windows x Microsoft Management Console MMC for Computer Management.

There are currently no plans to provide this capability in the Samba command-line tool set. The location of this file on your system will depend on how Samba was compiled. The best tool for share permissions management is platform-dependent. Choose the best tool for your environment. From the menu select Computer , then click on Shared Directories. Click on the share that you wish to manage and click the Properties tab, then click the Permissions tab.

Now you can add or change access control settings as you wish. For example, in Windows x, right-click on the shared folder, then select Sharing , then click on Permissions. If you are not logged onto a domain you will be prompted to enter a domain login user identifier and a password.

This will authenticate you to the domain. If you are already logged in with administrative privilege, this step is not offered. If the Samba server is not shown in the Select Computer box, type in the name of the target Samba server in the field Name:.

In the right panel, double-click on the share on which you wish to set access control permissions. Then click the tab Share Permissions.

It is now possible to add access control entities to the shared folder. Remember to set what type of access full control, change, read you wish to assign for each entry.

Be careful. If you take away all permissions from the Everyone user without removing this user, effectively no user will be able to access the share. This is a result of what is known as ACL precedence. Everyone with no access means that MaryK who is part of the group Everyone will have no access even if she is given explicit full control access.

Windows NT clients can use their native security settings dialog box to view and modify the underlying UNIX permissions. This ability is careful not to compromise the security of the UNIX host on which Samba is running and still obeys all the file permission rules that a Samba administrator can set.

When trying to figure out file access problems, it is vitally important to find the identity of the Windows user as it is presented by Samba at the point of file access. This can best be determined from the Samba log files.

When the menu pops up, click on the Properties entry at the bottom of the menu. This brings up the file Properties dialog box. Click on the Security tab and you will see three buttons: Permissions , Auditing , and Ownership. The Auditing button will cause either an error message "A requested privilege is not held by the client" to appear if the user is not the NT administrator, or a dialog intended to allow an administrator to add auditing requirements to a file if the user is logged on as the NT administrator.

This dialog is nonfunctional with a Samba share at this time, because the only useful button, the Add button, will not currently allow a list of users to be seen.

Clicking on the Ownership button brings up a dialog box telling you who owns the given file. The owner name will be displayed like this:.

Click on the Close button to remove this dialog. If the parameter nt acl support is set to false , the file owner will be shown as the NT user Everyone. The Take Ownership button will not allow you to change the ownership of this file to yourself clicking it will display a dialog box complaining that the user as whom you are currently logged onto the NT client cannot be found. The SAMBA file system implementation on Linux supports access control lists, but the feature must be explicitly enabled via the acl mount attribute.

It is possible to enable this feature dynamically, as:. We could use the command:. As we are establishing this ACL for the directory, it applies to its contained files and subdirectories.

Skip to primary navigation Skip to main content Skip to primary sidebar Skip to footer navigation. When I transfer files or folders using Samba from a Windows computer to a Kubuntu computer, the file's owner is set to "Nobody" and I cannot access it.

I can change the ownership using the command sudo chown and that works fine, except I don't want to type all of that whenever I transfer a file or a folder. I'd like to right click on the folder in Dolphin and select an option and have it done automatically. Is there a way to make that happen? Or, even better, not have it assigned to "Nobody" in the first place The easiest way to resolve this is to make "nobody" look like you - at least for this share.
