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.


# 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 ''


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.


Configuring a listen-address is essential for the service to work.

The resulting configuration will look like:

vyos@vyos# show service
 tftp-server {
    directory /config/tftpboot
    listen-address 2001:db8:ffee::1
