Device administration
Use USB devices with .all files
The following functionality is available from firmware version 4910 onwards.
A .all file is a special file that contains all of the firmware and configuration files in a single file that
has the file extension .all and is an exact copy of the TransPort router in its current state. This .all
file can then be applied to another TransPort router, as long as it is the same model.
1 To extract a .all file, use the Digi Flash Writer software.
2 Copy the extracted .all file to a USB storage device and insert the device into the TransPort
router.
3 Issue the command dir u: to confirm that the TransPort can access the USB device.
4 To copy the .all file onto the TransPort router, from the command line enter this copy
command:
copy u:mr4110.all t.all
Replace mr4110.all with the correct .all file name. The t.all destination name can be any
destination. The source file (in this example, mr4110.all) must adhere to the 8.3 filename
convention, owing to limits of the FAT file system, or the process will fail.
USB security
To prevent unauthorized access to a TransPort router using a USB storage device, such as inserting
a USB storage device with an autoexec.bat file designed to copy usernames and passwords, etc.,
there are several commands available:
1 Use the usbcon command to define an access key. If the .bat file does not contain the matching
key, it will not be allowed to execute.
2 Use the uflash command's put parameter to encode the matching key onto the file.
Note When using the uflash command, do not prefix the filename with u: as the uflash command
can only act on files stored on a USB storage device.
For example:
To create a key, enter:
▪
usbcon 0 flashkey
To encode this key onto a file called autoexec.bat on the USB storage device, enter:
▪
uflash autoexec.bat put
To remove a key from a file, use the uflash command parameter clr:
▪
uflash autoexec.bat clr
Note To use the uflash command, you must be logged onto the router with Super access level.
By default, an autoexec.bat file executes when a USB drive is inserted. You can execute other batch
files. To control this behavior, enter:
usbcon 0 batfile <off|on>
