Various tftp errors using get and put commands
by JockVSJock from LinuxQuestions.org on (#5E3YJ)
Using RHEL7 for tftp client, not able to put and get a basic text file via tftp. The tftp server is RHEL8 (we have self-support, so don't have the option to open a case).
I've disable SELinux and Firewalld on both server and client.
When using the get command, I'm able to download the text file, but its empty.
When I use the put command for a text file, I get a "client timed out" error.
I tail /var/log/messages and don't see anything odd.
