Sendmail

[Greg Ludewig]

What’s the best way to turn off the sendmail utility that seems to be scheduled to run periodically (once an hour?) on the OCG system? Each time it runs it transfers bytes over my cell connection, (even though I assume there is no email to send). We don’t want this traffic added to our data usage.

Sendmail can be invoked periodically if it is trying to email the output of a cron job. It won’t send any mail by default though since it isn’t configured with any SMTP server.

The most likely reason is the default cron job that runs ntpdate periodically to sync the time on the OCG. Feel free to disable it or change the interval.

You can run ‘crontab -l’ as root or look in /var/cron/tabs/root to see the jobs.
