today i will show you how easy is to do the installation of a TFTP Server in your linux machine. if you have a linux box you will see how easy it is to install TFTP Server. the first step in installing TFTP Server is to login to your server with ssh. i am using red hat fedora core so these are the shell commands i use for installing TFTP Server.

yum install tftp-server


when the installation completes you need to enable it, so send this command:
nano /etc/xinetd.d/tftp
NOTE: i am using nano to edit, but you can use your favorite editor to change the configuration file

look for the line:
disable = yes


change it to:
disable = no


after you have made the changes and saved the file, start the server
/sbin/service xinetd start


now that you have started your TFTP server, you can start using.. but wait.. where are the files going to go.. good questions. send this command:
ls /


you will see a directory called tftpboot/ thats where the root FTFP server files are located

hope that helps, i tried to make this TFTP Server step by step tutorial as simple as possible
