I was under the impression that most implementations of tftp are very picky
about the permissions and I would think they would NOT share any files
owned by root.

For example see if there's a tftp group already created and maybe chown the
file (and maybe its directory) to tftp:tftp ?

Does the man page for your version of tftpd say anything about the default
permissions?

Also I suggested you try using a client to put a file in the server's
directory. What permissions does it give that file? I would think it might
be the same permissions needed for reading a file.

If you can't tell I'm stabbing in the dark but suggesting how I would go
about it. I ALWAYS start with the man page. The information might be
inscrutable, but there's usually some nugget of information that gets me
closer to understanding.
