When you are trying to analyze/debug tftpd service on your linux boot server , you expect tftpd to return more debug information on the logs. To setup tftp in debug mode, use -v option in “server_args”. As many as “-v” option you use , more debug log information you get. Try it.
service tftp
{
disable = no
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -v -v -s /tftpboot
per_source = 11
cps = 100 2
flags = IPv4
}
