Daytime - TCP port 13 Echo - TCP port 7Note that you will need to open these ports on your firewall.
dnf install xinetd vi /etc/xinetd.d/daytime-stream vi /etc/xinetd.d/echo-stream service xinetd start telnet localhost 13The "vi" lines must find the disable line in the config file and change the setting from yes to no. Then the service gets restarted. I use telnet to verify that all is well.
