Wall execution problems from cron

So I've been tasked with creating a shell script to run in a cron every few minutes to check duplex settings on my eth0 nic card. I would like for the server to send a wall message to whoever is on the console or in a terminal session. Below is what I have so far.

Code:

0,10,20,30,40,50 * * * *  /home/acc4000d/test10

I have it in my root's cron so that wall will run. Can someone tell me what I'm missing for the wall to actually happen?

Script looks like this;

Code:

#!/bin/bash
DUPLEX=$(ethtool eth0 | sed -n 's/Duplex:\(.*\)/\1/p')
if [ $DUPLEX = Half ]
then /usr/bin/wall duplex_error 
fi

annnnd the wall message file is called "duplex_error"

       systemd-ask-password-wall.path

DESCRIPTION

       systemd-ask-password-console.service is a system service that queries the user for system passwords (such as hard disk encryption keys and
       SSL certificate passphrases) on the console. It is intended to be used during boot to ensure proper handling of passwords necessary for
       boot.  systemd-ask-password-wall.service is a system service that informs all logged in users for system passwords via wall(1). It is
       intended to be used after boot to ensure that users are properly notified.

       See the developer documentation[1] for more information about the system password logic.

       Note that these services invoke systemd-tty-ask-password-agent(1) with either the --watch --console or --watch --wall command line
       parameters.
