TFTP Server

Used version

  • Ubuntu 10.04 x86 in vmware player

Installation

user@ubuntu:~$ sudo apt-get install xinetd tftpd tftp

Configuration

To cofigure TFTP the file /etc/xinetd.d/tftp must be created and filled with the following content. This configuration uses the directory /tftpboot. 

service tftp
{
  socket_type             = dgram
  protocol                = udp
  wait                    = yes
  user                    = root
  server                  = /usr/sbin/in.tftpd
  server_args             = -s /tftpboot
  per_source              = 11
  cps                     = 100 2
}

<note> The directory requires at least the access authorisation “dr-xr-xr-x”. </note>

<note> After the configuration was changed the server should be restarted: 

user@ubuntu:~$ sudo service xinetd restart

</note>

Firewall & port forwarding

TFTP uses port 69 UDP. This port must be opened. How to configure port forwarding on a Windows-XP host system is described here: Port Forwarding.
