:abbr:`TFTP (Trivial File Transfer Protocol)` 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.
|
|
|
|
Configuration
|
|
=============
|
|
|
|
.. cfgcmd:: set service tftp-server directory <directory>
|
|
|
|
Enable TFTP service by specifying the `<directory>` which will be used to serve
|
|
files.
|
|
|
|
.. hint:: 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.
|
|
|
|
.. cfgcmd:: set service tftp-server listen-address <address>
|
|
|
|
Configure the IPv4 or IPv6 listen address of the TFTP server. Multiple IPv4 and
|
|
IPv6 addresses can be given. There will be one TFTP server instances listening
|
|
on each IP address.
|
|
|
|
.. note:: Configuring a listen-address is essential for the service to work.
|
|
|
|
.. cfgcmd:: set service tftp-server allow-upload
|
|
|
|
Optional, if you want to enable uploads, else TFTP server will act as a
|
|
read-only server.
|
|
|
|
Example
|
|
-------
|
|
|
|
Provide TFTP server listening on both IPv4 and IPv6 addresses ``192.0.2.1`` and
|
|
``2001:db8::1`` serving the content from ``/config/tftpboot``. Uploading via
|
|
TFTP to this server is disabled.
|
|
|
|
The resulting configuration will look like:
|
|
|
|
.. code-block:: none
|
|
|
|
vyos@vyos# show service
|
|
tftp-server {
|
|
directory /config/tftpboot
|
|
listen-address 2001:db8::1
|
|
listen-address 192.0.2.1
|
|
}
|
|
|
|
