Listing all Windows disks

A special feature for the Windows operating system was added to BarracudaDrive in version 3.0 that allows the server to list all disks in windows as directories. The -r command line option is implicitly set to -rC:/, where C: is the disk the server is started from, unless the option is explicitly set at startup.

You can set the command line option to -r/. The -r/ command line option tells BarracudaDrive to list your Windows disks as directories.

Opening a browser window to http://localhost/drive/ will show you something like:

The list includes all disks, including your A: drive, your CDROM's, etc. You must configure the constraints to disallow access to all removable devices. The web-server will deadlock and wait for the user to click on "the no disk popup window" before the web-server resumes control.

The image below shows you what happens when we press the "Web Folder" button in Internet Explorer:

The popup will appear on the machine running the server and not on the machine running the web-browser. In the above example, we are running the web-server and web-browser on the same machine, which makes it possible for us to press the "Cancel" button to resume the web-server. You will not be able to press this button when connecting to the server from another computer, which means that your web-server will deadlock until you get to the computer and press the "cancel" button.

We get the following Web-Folder window after pressing the "Cancel" button several times:

We will get the same same popup window if we try to click on any of the removable drives. What we must do is prevent BarracudaDrive from listing the removable drives A:, D:, E:, and F:, as shown in the above image. We disable the disks by using the constraints Editor.

• The name of the constraint is of no importance. We named the constraint RemovableDisks in the above example.
• The URL's field in the Constraints Editor must be a list of all of your removable disks.
• The Roles field must be empty, which means that it applies to all Roles and all users.
• The Methods field must contain 'none'.

You should see something like the following after you have applied the new constraint.

In our case, the Z: drive is a network drive. You can remotely reach network drives via the computer running BarracudaDrive. This means that if you have a LAN with several computers, all computers can be made accessible remotely via the Internet by running BarracudaDrive on one of the computers on your LAN.
