I have a tftpd server S running on centos 7 and managed by systemd
It is not respoding to A server which is sending the tftp read request RRQ.
I do see the RRQ packets coming from A to S, but S never responds back from
a different port Y to A
So this part is working fine

But I do not see any attempts to even send a data packet back in my packet
capture running on S
So this event is not occuring, as if my tftpd server is dead. I have the
firewalld turned off on S to eliminate
the possibility that firewalld blocking those packets from reeaching to
tftpd daemon. I also turned off selinux to eliminate
any permission issue.

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
