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, the filename should not be prefixed with u:, as the
uflash command can only act on files stored on a USB storage device.
For example:
• To create a key, enter the command:
usbcon 0 flashkey
• To encode this key onto a file called autoexec.bat on the USB storage device, enter the
command:
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 is executed if found when a USB drive is inserted. Other batch
files can also be executed. To control this behavior, issue the following command:
usbcon 0 batfile <off|on>
