When I log into a server, I get You have mail.
With alpine and sudo alpine I've deleted all my and root's emails, but there is also a file /var/spool/mail/smmsp. How can I check email from that user?
Running an Ubuntu Server on a Eaton 3S 700VA UPS. The Eaton's USB connection goes into my Ubuntu Server. I'm trying to use NUT to manage the UPS.
After sudo su'ing
cat /etc/nut/ups.conf:
[eaton]
driver = usbhid-ups
port = auto
desc = "Eaton 3S"
upsdrvctl -t start

I have an Eaton 3S 700VA UPS connected to my modem, QNAP TS-412 and an Ubuntu Server. The Eaton's USB connection goes into my Ubuntu Server.
I was wondering what software is the best for managing power interruptions. Specifically, I want to get the Ubuntu Server to tell the QNAP to shut down when there is no power, send an email to my gmail, and shutdown.
