F28 problems with tftp server firewall permissions

[Robert Moskowitz]

I am trying to set up tftp server on my workstation to manage some switches.

I have done the following:

dnf install tftp tftp-server
firewall-cmd --add-service=tftp --permanent
firewall-cmd --reload
systemctl start tftp

I can get files from a local terminal window with:

tftp localhost -cv file

I had problems with put until I saw that the file had to preexist. I did 
that with touch file on my system.

From a F24 notebook on the same subnet as the one running tftp server, 
though I cannot get the file.  I get:

Transfer timed out.

I also tried:

firewall-cmd --add-port=69/udp --permanent

but no different.

I don't see anything in the tftp.service file to indicate anything there.

What am I missing?

thanks
