Configure TFTPD Server in Ubuntu

I recently needed a TFTP server in Ubuntu for PXE booting my MythTV system. Up until now I was using the built-in DnsMasq server, which was great. When I moved my DHCP service to my Linksys router I needed stand-alone TFTP service. Hopefully this step-by-step HowTo will help someone get up an running quickly.

1. The first step is to install the TFTP client and server packages on your system. The client, tftp-hpa, is not necessary, but helps to debug your system if anything goes wrong.

   sudo apt-get install tftp-hpa tftpd-hpa



2. The default directory location to store your TFTP files is /var/lib/tftpboot. You can chose your own location if you don't want to use the default. For now, setup the directory permissions of the TFTP server root directory:

   sudo mkdir /var/lib/tftpboot
   sudo chown nobody.nogroup /var/lib/tftpboot
   sudo chmod 777 /var/lib/tftpboot



3. Edit the TFTP server configuration file, /etc/default/tftpd-hpa, to put the service in daemon mode. Also, if you are using a custom TFTP directory, change /var/lib/tftpboot to the correct directory location.
   
   

   /etc/default/tftpd-hpa
   #Defaults for tftpd-hpa RUN_DAEMON="yes" OPTIONS="-l -s /var/lib/tftpboot"



4. Start the TFTP init script.

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



5. There should be an indication that the service started. Also, use netstat to check the port has been opened:

   netstat -a |grep tftp



6. After adding a file the TFTP server directory, you should be able to access a file using the TFTP client. Assuming the file /var/lib/tftpboot/pxelinux.0 exists, try:

   tftp localhost -c get pxelinux.0

   You will know that everyhing worked if the file pxelinux.0 now exists in your current directory.
