TFTP:
As its name says,
Trivial File Transfer Protocol
is a very simple protocol for transferring files, derived
from the full FTP. Generally used exactly for this kind of tasks,
automated transfer of configuration
or
boot files between machines in a local environment. This is because it has no security, it does not even,
provide authentication. Its advantages are simplicity of design and very low usage of memory, it has been
implemented on top of the UDP using port number 69, it does not require TCP!
This makes it is ideal for simple machines such as routers with limited data storage!
TFTP is currently defined by RFC 1350. It is seldom used interactively, like the FTP, by human users,
instead it is excellent for machines simpler than a computer, networked devices that do not have the
capabilities of “true” computers, but still need to be able to do file transfers.
Due to the lack of security, it is dangerous to use it over the Internet. Thus, TFTP is generally only used on
private, local networks.
After enabling the TFTP section, you simply enter the
address where the configuration file is stored, then the full
path, and finally the port number to be used.
By default, the standard port for TFTP is used, number 69:
