Purpose

The purpose of this page is to contain information on how to setup a TFTP server on Linux. This is useful for downloading Linux kernel images to the target board during development.

Using RedHat Enterprise Linux v4 (RHEL4)

You can check to see if a TFTP server is set up with the following command:

host $ rpm -q tftp-server

You should expect to see output similar to:

tftp-server-0.39-2

NOTE: Your version may be different than the one listed above. This is OK, the version above is just an example.

If it is not setup, you can follow these steps:

1. Download a TFTP server for your Linux host. You can search the internet for "tftp-server". You can find the RPM package for download here
2. Install the TFTP server package

   host $ rpm -ivh <tftp-server package name>

3. Confirm that TFTP is installed

   host $ /sbin/chkconfig --list | grep tftp

4. Turn on the TFTP server

   host $ /sbin/chkconfig tftp on

The default root location for TFTP files is /tftpboot.

Using Ubuntu

There are multiple options for TFTP servers in Ubuntu, below are two possibilities atftp and tftpd-hpa.

Using atftp in Ubuntu 8.04 LTS

To setup atftp on Ubuntu 8.04 LTS, you can follow these steps:

Install atftp Server in Ubuntu

host $ sudo aptitude install atftpd

This will complete the installation

Using atftpd

By default atftpd server starts using inetd so we need to tell atftpd to run as a server directly, not through inetd. Edit /etc/default/atftpd file using the following command

host $ sudo gedit /etc/default/atftpd

Change the following line

USE_INETD=true

to

USE_INETD=false

also change the directory at the end of the file to /tftpboot

save and exit the file

Now you need to run the following command

host $ sudo invoke-rc.d atftpd start

Configuring atftpd

First you need to create a directory where you can place the files

host $ sudo mkdir /tftpboot

host $ sudo chmod -R 777 /tftpboot

host $ sudo chown -R nobody /tftpboot

host $ sudo /etc/init.d/atftpd restart

Using tftpd-hpa in Ubuntu

This was verified in Ubuntu 9.04 but likely applies to other releases as well.

Install tftpd-hpa

Installation is an easy one line command:

host $ sudo apt-get install tftpd-hpa

Configure tftpd-hpa for Daemon Operation

Configure the newly installed TFTP to run as a daemon by editing the /etc/default/tftpd-hpa file and replacing RUN_DAEMON="no" with RUN_DAEMON="yes", note that this file also defines where your TFTP server is serving from, the default location is /var/lib/tftpboot but may be changed in this file if desired:

host $ gksudo gedit /etc/default/tftpd-hpa

Start the TFTP service

Now start the newly configured TFTP service with this command:

host $ sudo /etc/init.d/tftpd-hpa start

[Ubuntu 10.04] use

host $ sudo service tftpd-hpa start
