1. Install genisoimage.

sudo apt install genisoimage

2. Create an ISO "files.iso" containing the content of "folder".

Replace files.iso and /path/to/folder with the preferred ISO name and suitable path to the folder content.

genisoimage -o files.iso /path/to/folder

3. Mount the newly created ISO.

Use the VirtualBox GUI to mount the newly created ISO which is a virtual VM CD/DVD drive.

4. Create the /media/cdrom folder inside Whonix-Workstation ™.

sudo mkdir -p /media/cdrom

5. Attach/mount the ISO to the VM.

sudo mount /dev/sr0 /media/cdrom

6. Navigate into the folder.

cd /media/cdrom

7. Review the files.

dir

This procedure is recommended.

1. Shut down any running Whonix ™ virtual machines.

• It is recommended to back-up data to avoid any potential data loss.
• Never run the Whonix ™ VM that is currently mounted because that can lead to data loss. Always unmount first.

2. Update the package lists.

sudo apt update

3. Install qemu.

sudo apt install qemu

4. Load the Network Block Device kernel module.

sudo modprobe nbd max_part=16

5. Attach the disk image (.vmdk) to one of the newly created network block devices.

The example below uses Whonix-ws.vmdk. This is stored in the default place created by VirtualBox for VMs: /home/user/VirtualBox VMs.

sudo qemu-nbd -c /dev/nbd0 '/home/user/VirtualBox VMs/Whonix-Workstation/Whonix-Workstation-13.0.0.1.5-disk1.vmdk'

^{[2] [3]}

6. Create a mount point.

For example.

sudo mkdir -p /mnt/workstation

A partition manager like cfdisk could be run on the block device, but it is more likely you will want to mount an individual partition.

sudo mount /dev/nbd0p1 /mnt/workstation

The procedure is complete. A new partition with Whonix-Workstation ™ mounted inside it will be visible.

7. Unmount everything when finished.

sudo umount /mnt/workstation

sudo qemu-nbd -d /dev/nbd0

After unmounting, the Whonix ™ VM can be safely restarted.

1. The virtual machine that will be edited needs to be powered off.
2. In VirtualBox: Click on "Settings" for the Whonix ™ Workstation that you wish to copy files from → click on "Storage".
3. Select "Storage" settings → click on the square with a + sign → select "add hard disk" (located next to the "Controller: Whonix ™" entry).
4. In the next window that appears, click on create new disk.
5. When prompted: Choose a "hard drive file type" → select "VDI".
6. When prompted: Choose "storage on physical hard drive" → select "dynamically allocated".
7. In the next window: Type "WhonixTransferBackup" for the drive name → choose the needed storage capacity. In many cases, the default "8.00 GB" will be enough.
8. After returning to the "Settings" window, click the "OK" button.
9. Start the Whonix ™ Workstation that you wish to transfer files from. After reaching the desktop, open a Terminal/Konsole session.
10. Format the newly created drive:

    sudo fdisk /dev/sdb

    sudo fdisk /dev/sdb

11. At the command prompt: Type "n" create a new partition → press "enter" to choose the default options when prompted until returned to fdisk's main menu → type "w" to write the partition and exit fdisk.
12. In the terminal session, type:

    sudo mkfs.ext4 /dev/sdb1

    sudo mkfs.ext4 /dev/sdb1

13. Create a new directory to be the mount point for the drive:

    mkdir temp

    mkdir temp

14. Mount the new drive:

    sudo mount /dev/sdb1 temp

    sudo mount /dev/sdb1 temp

15. Change the permissions of the mount folder so it is possible to write to the drive:

    sudo chmod 777 temp

    sudo chmod 777 temp

16. Copy selected files to the new drive by copying them to the "temp" folder. This is possible in the terminal, with the file browser and so on. Once all files have been copied to the "temp" folder, shut down the Whonix ™ Workstation.
17. After the Whonix ™ Workstation has closed, open the "Virtual Media Manager" in VirtualBox: Click on "File → Virtual Media Manager".
18. Locate the new VDI file created in steps 2-8 → click on it → click the "copy" button → click the "next" button.
19. When prompted to choose a "hard drive file type," select "VDI".
20. When prompted to choose "storage on physical hard drive," select "dynamically allocated".
21. In the next window: type "WhonixWorkstationFileTransfer" for the drive name → choose a folder to store the VDI file → click on the "copy" button. ^[4]
22. After returning to the "Virtual Media Manager" window, click the "close" button.
23. In the main VirtualBox window: Click the Whonix ™ Workstation version that you want to copy the files into → click "settings".
24. Navigate to the "storage" section → click on the square with a + sign → select "add hard disk" (located next to the "Controller: Whonix ™" entry).
25. In the next window: Click on "choose existing disk" → find the saved "WhonixWorkstationFileTransfer.vdi" file and select it.
26. After returning to the "settings" window, click "OK."
27. Start the Whonix ™ Workstation that you wish to copy your files into. After reaching the desktop, open a Terminal/Konsole session.
28. Create a new directory to be the mount point for the drive:

    mkdir temp

    mkdir temp

29. Mount the new drive:

    sudo mount /dev/sdb1 temp

    sudo mount /dev/sdb1 temp

30. Finally, copy selected files into the Whonix ™ Workstation. When copying is finished, shut down the Whonix ™ Workstation and delete the temporary "file transfer" VDI files through Virtual Media Manager.

This procedure is not recommended for security reasons. ^[5]

1. Adjust the Linux user group.

For Linux hosts, the user that is running VirtualBox must be a member of linux user group vboxusers. ^[6] To add the current user to group vboxusers, run.

sudo adduser $(whoami) vboxusers

2. Reboot.

A reboot or re-login is required.

3. Plug in the USB device.

USB devices are plugged into Virtual Machines through the device menu in VirtualBox.

4. Mount the USB device.

Automount of USB devices is disabled in Whonix ™ by default. To mount the device, try: Start menu → System Settings → Removable Media or manually mount the device.

Also refer to this old forum topic ^[archive]. Failures or successes can also be shared in a new forum discussion ^[archive].

5. Optional: Install the ntfs-3g package.

If the USB device is formatted with NTFS, it is necessary to install the ntfs-3g driver package ^[archive] and run a special mount command, see: Transfer Files from Whonix ™ - USB ^[archive] and Can’t enable USB Drive in VirtualBox – troubleshooting help needed ^[archive].

1. Adjust Whonix-Gateway ™ firewall settings.

Modify Whonix-Gateway ™ User Firewall Settings.

sudo mkdir -p /usr/local/etc/whonix_firewall.d

sudoedit /usr/local/etc/whonix_firewall.d/50_user.conf

## Please use "/etc/whonix_firewall.d/50_user.conf" for your custom configuration,
## which will override the defaults found here. When {{project_name}} is updated, this
## file may be overwritten.

nano /etc/whonix_firewall.d/30_whonix_gateway_default.conf

2. Add.

GATEWAY_ALLOW_INCOMING_SSH=1

3. Restart the firewall.

Make sure this is run on Whonix-Gateway ™!

sudo /usr/bin/whonix_firewall

4. Install openssh-server inside Whonix-Gateway ™.

Make sure this is run on Whonix-Gateway ™! Run the command once.

sudo apt install openssh-server

5. Add port forwarding from host into the virtual machine.

Make sure this is run on the host! Run the command once.

Open a terminal. This will forward connections from the host to 127.0.0.1:2200 to the SSH server running inside Whonix-Gateway ™ on port 22.

VBoxManage modifyvm "Whonix-Gateway" --natpf1 "ssh",tcp,127.0.0.1,2200,,22

If it is necessary to undo this change, run.

VBoxManage modifyvm "Whonix-Gateway" --natpf1 delete "ssh"

To verify the change, run.

VBoxManage showvminfo "Whonix-Gateway"

Search for lines beginning with NIC. For example:

NIC 1 Rule(0):   name = ssh, protocol = tcp, host ip = 127.0.0.1, host port = 2222, guest ip = 127.0.0.1, guest port = 22

6. Open a SSH session on the host.

Make sure this is run on the host!

As user.

ssh user@127.0.0.1 -p 2200

Or as root.

ssh root@127.0.0.1 -p 2200

7. Create a folder which will be used to mount the image.

Perform this step on the host or mount Whonix-Gateway ™ as a folder.

This folder must exist before trying to mount.

mkdir ~/mountgateway

8. Mount the folder.

Make sure this is run on the host!

As user.

sshfs user@127.0.0.1:/ -p 2200 ~/mountgateway

Or as root.

sshfs root@127.0.0.1:/ -p 2200 ~/mountgateway

Developers / experts only! Only for debugging!

1. Adjust Whonix-Workstation ™ firewall settings.

Modify Whonix-Workstation ™ User Firewall Settings

sudo mkdir -p /usr/local/etc/whonix_firewall.d

sudoedit /usr/local/etc/whonix_firewall.d/50_user.conf

## Please use "/etc/whonix_firewall.d/50_user.conf" for your custom configuration,
## which will override the defaults found here. When {{project_name}} is updated, this
## file may be overwritten.

nano /etc/whonix_firewall.d/30_whonix_workstation_default.conf

2. Add the necessary port.

Replace 80 with the actual port that should be opened.

EXTERNAL_OPEN_PORTS+=" 80 "

Save.

3. Reload the firewall.

Reload Whonix-Workstation ™ Firewall.

sudo whonix_firewall

1. SSH from the host into Whonix-Gateway ™.

host → Whonix-Gateway ™

ssh -t user@127.0.0.1 -p 2200 "ssh.anondist-orig user@10.152.152.11"

root@ can also be substituted in the above command.

2. Create a directory to mount Whonix-Workstation ™.

mkdir ~/mountworkstation

3. SSH into Whonix-Workstation ™ and map to localhost:2222.

Whonix-Gateway ™ → Whonix-Workstation ™

Perform this step on the host.

ssh -f user@127.0.0.1 -p 2200 -L 2222:10.152.152.11:22 -N

root@ can also be substituted in the above command.

4. Mount the Whonix-Workstation ™ folder on the host.

sshfs -p 2222 user@127.0.0.1:/ ~/mountworkstation

If these instructions did not work, try the alternative standalone instructions SSHFS into Whonix-Workstation.

• Developers / experts only! Only for debugging!
• Warning: If a guest image file is mounted and the image is compromised by malware, the system can be infected. ^[8]

These instructions are broken because the virtualbox-fuse package is no longer available in Debian jessie and above. ^[9] They have been kept in case the situation changes.

1. Optional: Update the system.

sudo apt update

2. Install the VirtualBox vdfuse utility. ^[11]

sudo apt install virtualbox-fuse

3. Edit the /etc/fuse.conf file.

sudo vi /etc/fuse.conf

Uncomment the line #user_allow_other and then save the file.

4. Set the permissions on /etc/fuse.conf.

sudo chmod 644 /etc/fuse.conf

5. Create a mount point and mount the Whonix ™ Workstation image.

This example shows a .vmdk file type, but any VirtualBox file type should work (VMDK, VDI, VHD, or raw).

mkdir /mnt/whonix

vdfuse -f /path/to/Whonix-Workstation/Whonix-Workstation-disk1.vmdk /mnt/whonix

The path /mnt/whonix/ will now contain files like EntireDisk, Partition1, etc.

6. Mount Partition1 at a second mount point.

mkdir /mnt/workstation

sudo mount -o loop /mnt/whonix/Partition1 /mnt/workstation

7. Copy files to/from the Whonix ™ workstation disk image.

8. Unmount each of the mount points.

sudo umount /mnt/workstation

sudo umount /mnt/whonix
