How to forcefully mark down pfSense Gateway as down

Posted on in Categories last updated October 28, 2016

I have two internet connections (fiber and 4G LTE) configured in load balanced mode using pfSense FreeBSD based firewall. One of my connection is running out of bandwidth quota. How can I force and turn off this interface to save bandwidth until month end and enable it again from next billing cycle?

I am getting the following error in my cron job log file /var/log/cron.log:
       Aug 22 01:59:01 server2 cron[7510]: Error: bad username; while reading /etc/cron.d/backups
I have job entry as follows to run a job at 00:50 every day for root user:

How do I fix this problem on Linux or Unix-like system?
