You seek to troubleshoot a suspected hardware problem with a Dell-based hardware appliance from Symantec.


You seek to troubleshoot hardware on one of the following:

  • Symantec Web Gateway (SWG) 8450
  • Symantec Web Gateway (SWG) 8490
  • Symantec Messaging Gateway (SMG) 8340
  • Symantec Messaging Gateway (SMG) 8360
  • Symantec Messaging Gateway (SMG) 8380
  • Symantec Traffic Shaper


To collect a DSET report from a Symantec Linux based appliance

  1. Download the DSET .iso from
  2. Confirm the downloaded .iso file is intact by comparing file information for the DSET .iso to the following known good characteristics:
    Size in bytes: 1,336,934,400 bytes
    MD5 hash: 7bff1dc1023ad6022c8e751c0074978b
    SHA-1 hash: dce79f8af6cf9c0bb0e73da69674cdb93c793330
  3. Burn the .iso to cdrom media using a known good cd burner
  4. Insert the cdrom into the Symantec appliance you seek to troubleshoot
  5. Start or restart the appliance by pressing and releasing the physical power button

    NOTE: The boot sequence for this live cdrom is slow in comparison to the normal boot sequence of a Symantec appliance. Ignore on screen errors unless the boot sequence takes longer than one hour. A successful boot from this cdrom will result in a Linux X Windows session with an open X Window connected to a bash prompt. The screen offset may be off, resulting in a black horizontal bar across the screen and the top portion of the screen appearing at the bottom. If so, drag the window down where you can see all of it before continuing.
  6. Execute the DSET utility
  7. Copy the .zip archive containing the DSET data to a USB drive

To execute the DSET utility

  1. At the bash prompt, type: 

    When the DSET utility completes, it will display the name of the .zip file containing its collected data, but it wll not return you to the prompt.
  2. Press <CTRL>+<C> on the keyboard to return to the bash prompt


To copy the .zip archive containing the DSET data to a USB drive

  1. Insert a USB drive no larger than 2GB into one of the USB slots on the face of the SWG appliance
    NOTE: If you need to remove a USB device to free up a USB slot, remove the mouse.
  2. To create a folder to use as a mount point, at the bash prompt, type: 
    mkdir /mnt/usb
  3. To mount the USB drive, at the bash prompt, type: 
    mount /dev/sdb1 /mnt/usb
  4. To copy the DSET output to the USB drive, at the bash prompt, type: 
    cp /tmp/data/DSET*.zip /mnt/usb ; ls -l /tmp/data/DSET*.zip /mnt/usb

    The resulting output should show the same file name with different paths and the same filesize for both.
  5. To unmount the USB drive safely, at the bash prompt, type:
    umount /mnt/usb
