Changing the NFS-User Access Table

Each exported directory may have a list of users which are allowed to access to it. Access information is stored in the NFS User Access Table.

Adding a User

To add a user to the NFS User Access Table, on the NFS Server - Settings dialog box:

1. Select a directory in the Export Directories list box
   
   
2. Click on the Add User Access button.

The User Access window will appear on your display:

You should specify the following fields to map a remote user to the exported path:

• NFS Client Host
• User ID
• Group ID
• R/W access (i.e., the Read only check box)

After clicking OK the specified values will appear on the NFS User Access list box. Clicking on Cancel will not change the current access list.

Note: if you specify the NFS Client Host by its IP address (not by a host name), then you can use the '*' sign (an asterisk) as a wildcard character for a number of hosts (e.g., 192.168.136.*).

Also you can use an asterisk as a wildcard character for UserID and GroupID.

With each UNIX user mapped to a MS Windows local account, only the person login the UNIX machine with the matching UID/GID can access files in that account. Here, 'local account' is the account on the MS Windows system that you want to share-out files to the UNIX users (i.e. an exported path). 'UID/GID' are the numbers that matches the user account on the UNIX machine. To get UID/GID numbers, login to the UNIX machine and type 'id' at the prompt.

Removing a User

To remove a user from the NFS User Access Table, on the NFS Server - Settings dialog box:

1. Select a directory in the Export Directories list box
   
   
2. Select a user in the NFS User Access list box
   
   
3. Click on the Remove button.

Status

NFS-Server makes access control when remote users try to mount a directory. To view those directories of your PC that are being accessed by remote users, click on the Show Mounts button in the NFS-Server window. The Status Report window will appear on your display.

For each exported path, remote users are designated with HostName, UserID, and GroupID. The information in the dialog is dynamically updated (according to Refresh frequency).
