Need an tftp server for switch config files

[Robert Moskowitz]

I need to run a tftp server.  I have installed it on a F21 notebook.  I 
see basic starting instructions at:

http://docs.fedoraproject.org/en-US/Fedora/20/html/Installation_Guide/ch13s05s03.html

How do I control what directory it is using?  The README.secure talks 
about creating a user and group of tftp, but the install did not do that....

Besides the basic instructions to start the server, I know I have to 
open the udp port in firewalld.  But I want to know what directory it is 
using so I can put the config file there to download.

thanks
