Just edit your tftp file for xinetd like this:
*Change the IPto be the IPof the interface you want to listen on.
To test if your tftp is available on a certain IP range use nc -u yourip 69 to see if you can still connect (/var/log/messages or /var/log/syslog) should show the connection if it is open.

In Centos 7 tftpd will not work with selinux. Clients will not be able to connect and this is all you'll see in the log (then nothing more):
Sep 18 14:39:15 localhost xinetd: START: tftp pid=4331 from=192.168.1.65
On the client/computer side you will see this:
PXE-M0F: Exiting Intel Boot Agent

systemd is like the service manager for your Centos and other modern Linux distributions (including Debian/Mint/Ubuntu) allows you to enable services, stop them, restart them, check their status and even reboot your system.
The key commands or arguments you will use with systemctl are the following:
list-units [PATTERN...] List loaded units
pxe-32 tftp open timeout
The solution was to enable tftp in xinetd with "chkconfig tftp on".
See the troubleshooting below:
NetworkManager 0:off 1:off 2:off 3:off 4:off 5:off 6:off
This is something I often setup for clients because it's very helpful for people in datacenters, this allows custom OS installs on demand, you can customize it more by using kickstart etc.. but here's a base I use before customizing more:
This little script below will install everything you need to get booting by PXE Linux.
It also assumes you set a local IP (be sure not to overwrite your existing IP) on eth0:0 (note the :0) as 192.168.1.10 and it........
Need identd for port 113 ? Install authdyum install authd
Happy identing :)Actually it's not that simple.
It installs as an "xinetd" service and is disabled and turned off by deafult.
To enable it run:
chkconfig --level 3 auth on
service xinetd restart
This will set identd aka authd to start by default.
service xinetd resta........
