But what if you want to connect the DSM to an already existing NUT setup? The only thing that you can configure from the control panel is the server IP… let’s see how to configure the NUT server to handle connections from your DiskStation.
First of all, make sure upsd listens on the required network interface. Edit upsd.conf and add a couple of lines like these:
(by default it listens only on the loopback interface).
Then you should match your configuration to the one hardcoded in the DiskStation. You can use the values in this post for reference: in case Synology decides to change them in a future product, you can enable SSH on your device then look for the new values in /usr/syno/etc/ups/
The first thing to do is to change the name of the ups to… err… ups 🙂 This means editing ups.conf:
driver = ...
(remember to update your upsmon.conf file too, if you changed the name).
Next, you’ll need to create the user that Synology requires. Edit upsd.users and append these lines:
password = secret
Restart upsd, enable UPS support in DSM, enter the IP of your server and Bob’s your uncle. 🙂
