-===== Ubuntu x86 in VMware player =====
-Tested with Ubuntu
+====== TFTP Server ======
-  * 14.04
+===== Setting up TFTP Server in Ubuntu =====
-  * 12.04
-The following guide desribes how to install and setup a tftp server under Ubuntu, the default TFTP suite is tftp-hpa.
+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.
-To install the following step is needed:
+For example the TFTP server can be used to provide the u-boot, device tree blob and Linux kernel binaries for firmware updates in u-boot on the target hardware.
-<code bash>
+The first thing is to install install the client and the server package together with xinetd superserver.
-user@ubuntu:~$ sudo apt-get install xinetd tftpd tftp
+<code>
+sudo apt-get install xinetd tftpd tftp
 </code>
-The TFTP default directory is /var/lib/tftpboot. For convinience the following changes can be applied to the system:
+The next step is to create folder to act as TFTP root, the files for e.g. the firmware updates has to be stored there.
+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
+sudo /etc/init.d/xinetd restart
+</code>
-  * Creation of a new directory for the server
-  * setting the ownership for the tftp user
-  * add user to the tftp group to have rights to the tftpd dirctory
-<code bash>
+Now a new xinetd serivce has to be created  the file **/etc/xinetd.d/tftp** and add the following lines of code to it:
-user@ubuntu:~$ sudo mkdir -p /srv/tftpd
-user@ubuntu:~$ sudo chown <user>:tftp /srv/tftpd
+<code>
-user@ubuntu:~$ sudo chmod 775 /srv/tftpd
+service tftp
-user@ubuntu:~$ sudo usermod -a -G tftp <user>
+{
+protocol        = udp
+port            = 69
+socket_type     = dgram
+wait            = yes
+user            = nobody
+server          = /usr/sbin/in.tftpd
+server_args     = /tftpboot
+disable         = no
+}
 </code>
-Finally the server configuration for the TFTP server has to be changed:
+===== 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 nano /etc/default/tftpd-hpa
+user@ubuntu:~$ sudo apt-get install tftpd-hpa tftp-hpa
 </code>
-Change the following line to point to the new created directory:
+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="/srv/tftpd"
+TFTP_DIRECTORY="/home/tq/workspace/TQMa6x-BSP-REV.0104/platform-MBa6x/images"

+===== 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]].
