Ubuntu安裝TFTP Server

1. 安裝套件

$ sudo apt-get install xinetd tftpd tftp

2. 新增/etc/xinetd.d/tftp，建立tftpd config，server_args參數填入分享的目錄

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

3. 建立分享目錄，修改權限

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

4. 重新啟動xinetd

$ sudo /etc/init.d/xinetd restart
