Using the ReadyNAS to create a Network UPS for PCs

Just a little Information : it will not work with duo

Even though the UPS network monitor user interface element is disabled in FrontView for the Duo (I guess it's not part of Netgear's SOHO feature matrix?), so long as you have the root SSH add-in installed, it's actually very easy to enable UPS network monitoring for the Duo yourself:

1. Edit /etc/nut/upsd.conf to add the following line:

ACL localnet 192.168.0.1/24

...assuming that you want to permit UPS monitoring access to anyone on the 192.168.0.xxx subnet. If you are on a different network, modify the address and CIDR notation appropriately.

2. In the same file, edit the line that reads "ACCEPT monitor localhost readynas" and add the word "localnet" to the end, such that you have:

ACCEPT monitor localhost readynas localnet

3. Edit the file /etc/nut/upsd.users. Adjust the "allowfrom" line to read as follows:

allowfrom = localhost localnet

4. Tell the UPS daemon to reload its configuration files with "/sbin/upsd -c reload".

From there, it should be working! You can then install NUT on another system and monitor the UPS connected to your ReadyNAS. The following line in my client system's upsmon.conf worked very well:

MONITOR UPS@<insert_your_NAS_ip_here> 1 monuser pass slave
