====== TFTP Server ======

===== Ubuntu 14.04/16.04 x86 in vmware player =====

First you have to install xinetd tftp 

<code>
sudo apt-get install xinetd tftpd tftp
</code>


create the file **/etc/xinetd.d/tftp** and add the following lines of code to it: 

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

Then create a tftp folder and restart xinetd.
<code>
sudo mkdir /tftpboot
sudo chmod -R 777 /tftpboot
sudo chown -R nobody /tftpboot
sudo /etc/init.d/xinetd restart
</code>





===== Ubuntu 12.04 x86 in vmware player =====

The default TFTP suite is tftp-hpa. To install the following step is needed:

<code bash>
user@ubuntu:~$ sudo apt-get install tftpd-hpa tftp-hpa
</code>

The TFTP default directory is /var/lib/tftpboot.

Change the following line in ''/etc/default/tftpd-hpa'' to point to the images directory of the BSP:

<code>
TFTP_DIRECTORY="/home/tq/workspace/TQMa6x-BSP-REV.0104/platform-MBa6x/images"
</code>


To restart the TFTP server type:

<code bash>
user@ubuntu:~$ sudo service tftpd-hpa restart
</code>

To test the server copy some file to the server and get it back with 

<code bash>
user@ubuntu:~$ tftp 127.0.0.1 -c get <filename> 
</code>

===== Ubuntu 10.04 x86 in vmware player =====

==== Installation ====
<code bash>
user@ubuntu:~$ sudo apt-get install xinetd tftpd tftp
</code>

==== 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''.
<code>
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
}
</code>

<WRAP round info>
The directory requires at least the access authorisation "''dr-xr-xr-x''".
</WRAP>

<WRAP round info>
After the configuration was changed the server should be restarted:
<code bash>
user@ubuntu:~$ sudo service xinetd restart
</code>
</WRAP>

===== 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: [[vm#nat_network_address_translation|Port Forwarding]].
