I have not used tftp in awhile, but have you checked the permissions on the
file "jerry" in /tftpboot ? The file may be invisible to the daemon due to
the wrong group or file permissions.

You might also try to put a different file onto the server using tftp and
see what permissions the resulting file has.

The man page for your version of tftpd will likely contain some useful
information.
