 +==== 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
