Note: It is not possible
to overwrite the
management
password by TFTP –
the original password
will be maintained.
Using TFTP
You should be aware that the TFTP 'files' on the
A032 contain important configuration.
Overwriting them may cause your Nokia A032
to behave unexpectedly, or cease to function.
TFTP can be used to update the configuration
without knowledge of the management
password. This could allow unauthorized users
to update the unit.
There are two ways to disable TFTP access:
• Set a specific manager's IP address (see
page 46) to prevent unauthorized TFTP
transfers. See Management functions on
page 79.
• Set the security
