setup tftp service

• Install following packages.

  sudo apt-get install xinetd tftpd tftp
  

• Create /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.

  newer systems:

  sudo service xinetd restart
