How do I install and run a TFTP server?

Question

I have an embedded VxWorks target that needs to boot its kernel from my Ubuntu computer.

Answer 1

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.

I got TFTP service working great by using: sudo apt-get install xinetd tftpd tftp

Here is where the solution came from: http://mohammadthalif.wordpress.com/2010/03/05/installing-and-testing-tftpd-in-ubuntudebian/

And here is what's there: 1. Install following packages.

$ sudo apt-get install xinetd tftpd tftp

1. 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 }

1. 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

1. Restart the xinetd service.

sudo /etc/init.d/xinetd stop

sudo /etc/init.d/xinetd start

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, in

1. 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
