TFTP 설정

Install following packages.

sudo apt-get install xinetd tftpd tftp

Create /etc/xinetd.d/tftp

sudo nano /etc/xinetd.d/tftp

and put this entry

service tftp
{
protocol        = udp
port            = 69
socket_type     = dgram
wait            = yes
user            = nobody
server          = /usr/sbin/in.tftpd
server_args     = /tftpboot
disable         = no
}

Create a folder /tftpboot this should match whatever you gave in server_args. mostly it will be tftpboot

sudo mkdir /tftpboot
sudo chmod -R 777 /tftpboot
sudo chown -R nobody /tftpboot

Restart the xinetd service.

sudo /etc/init.d/xinetd restart

You must allow udp port 69 in firewall.
