TFTP
----
Trivial File Transfer Protocol (TFTP_) is a simple lockstep File Transfer
Protocol which allows a client to get a file from or put a file onto a remote
host. One of its primary uses is in the early stages of nodes booting from a
local area network. TFTP has been used for this application because it is very
simple to implement.
Example
^^^^^^^
.. code-block:: sh
# If you want to enable uploads, else TFTP server will act as read-only (optional)
set service tftp-server allow-upload
# Directory for TFTP server content
set service tftp-server directory '/config/tftpboot'
# On which addresses we want to listen for incoming TFTP connections? (mandatory)
set service tftp-server listen-address '2001:db8:ffee::1'
set service tftp-server listen-address '10.10.1.1'
.. note:: Choose your ``directory`` location carefully or you will loose the
content on image upgrades. Any directory under ``/config`` is save at this
will be migrated.
.. note:: Configuring a listen-address is essential for the service to work.
The resulting configuration will look like:
.. code-block:: sh
vyos@vyos# show service
tftp-server {
allow-upload
directory /config/tftpboot
listen-address 2001:db8:ffee::1
listen-address 10.10.1.1
}
