 ====== TFTP Server ======
-===== Ubuntu 14.04/16.04 x86 in vmware player =====
+===== Setting up TFTP Server in Ubuntu =====
-First you have to install xinetd tftp
+TFTP (Trivial File Transfer Protocol) is a simplified version of FTP (File Transfer Protocol),running on port 69. It can be setup with very litte effort.\\
+For example the TFTP server can be used to provide the binaries (u-boot, device tree blob and Linux kernel) for firmware updates in u-boot on the target hardware.\\
+\\
+The first thing is to install install the client and the server package, together with xinetd superserver.
 <code>
 sudo apt-get install xinetd tftpd tftp
 </code>
+The next step is to create folder to act as TFTP root, the files for e.g. firmware updates on the Starterkit must be stored here .\\
+Typically this folder is located at the root level and named **tftpboot**
+<code>
+sudo mkdir /tftpboot
+sudo chmod -R 777 /tftpboot
+sudo chown -R nobody /tftpboot
-create the file **/etc/xinetd.d/tftp** and add the following lines of code to it:
+</code>
+Now a new xinetd tftp serivce has to be configured by creating the file **/etc/xinetd.d/tftp** :
+<code>
+sudo nano /etc/xinetd.d/tftp
+</code>
+Add the following lines of code:
 <code>

 }
-</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>
+After setting up everything properly, the xinetd service must be restarted by the following command:
-===== 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"
+sudo service xinetd restart
-</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]].
