I have an embedded VxWorks target that needs to boot its kernel from my Ubuntu computer. How do I install and run a TFTP server?

TFTP Server Install and Setup

  1. Install the following packages.

     sudo apt-get install xinetd tftpd tftp

  2. Create /etc/xinetd.d/tftp and put this entry:

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

  3. Create a folder /tftpboot this should match whatever you gave in server_args. mostly it will be tftpboot.

     sudo mkdir /tftpboot
 sudo chmod -R 777 /tftpboot
 sudo chown -R nobody /tftpboot

  4. Restart the xinetd service.

    newer systems:

     sudo service xinetd restart

    older systems:

     sudo /etc/init.d/xinetd restart

Now our TFTP server is up and running.

Testing our TFTP server

  1. Create a file named test with some content in /tftpboot path of the TFTP server

    Obtain the IP address of the TFTP server using ifconfig command

  2. Now in some other system follow the following steps.

     tftp 192.168.1.2
 tftp> get test
 Sent 159 bytes in 0.0 seconds

    tftp> quit
    

    cat test

You can install atftpd and it will create a directory called /tftpboot in which you may place your files. Put especially the pxelinux.0 file there. Any future configuration will be addressed if it is necessary.

When you install the package with 

sudo apt-get install atftpd

it will use Debconf to prompt you for some choices. You can set many choices(server timeout may be useful), especially the basepath. You can also adjust the multicast range.
