Most Linux installations include a TFTP server and an automated method of launching the server upon receiving a TFTP request. The parent process for detecting a TFTP request and launching the TFTP server is called xinetd. However, you might have to enable the TFTP service. The TFTP file is located in the /etc/xinetd.d/ directory. The following is a sample TFTP file:
# default: off
# description: The tftp server serves files using the \
# trivial file transfer protocol. The tftp protocol is \
# often used to boot diskless workstations, download \
# configuration files to network-aware printers and to \
# start the installation process for some operating systems.
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot
disable = yes
per_source = 11
cps = 100 2
}
In this example, "disabled" is the default setting, and /tftpboot is the root directory for all client access.
To enable the TFTP service on your server, edit the disable line to read:
disable = no
