Using the ReadyNAS to create a Network UPS for PCs
The ReadyNAS can issue "UPS commands" to other devices, effectively allowing your UPS to be networked and shutdown client PCs. I've got my UPS connected to the NAS and setup using the procedure below.
Basically, you need to install WinNUT on your PC.
You also need to configure your ReadyNAS to communicate with the PC:
1. Connect the UPS to the NAS via USB.
2. Login to the web interface of your NAS.
3. Click SYSTEM --> POWER.
4. Scroll down to the UPS section.
5. Check the box that says "Enable network sharing of attached UPS"
6. Enter the IP address of the PC or the subnet (i.e. 192.168.1.0/24).
7. Edit the WinNUT configuration file (typically C:\Program Files\WinNUT\upsmon.conf). In my case, my ReadyNAS uses a static IP (192.168.1.2) and my computers use DHCP on the 192.168.1.0/24 subnet). I've edited out most author comments, just leaving the values I used:

- i followed the string above and got it to work!! thanks everyone for the tips.
two questions;
1 the NOTIFYFLAG values; do i need that? im not clear on what that does for me. at this point i dont have any value specified, like the default file.
2 in frontview, on the ups button, it shows i have 9 minutes of standby time on my ups. but....when i used the apc software, it said i had 25 minutes, which is more or less correct. i know this has nothing to do with winnut, but this is the first time i connected the ups to the readynas (figuring it better to protect the open files on the pc and use full journaling on the nas box). is the readynas just reading this incorrectly, or is that what it figures it will run before shutdown?
thanks,

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- Dave, thanks for the great instructions, but I am a little hesitant to go down that road, because super-poussin said:
So I was wondering if the SNMP for The DUO V 1.0 addon will enable me to do your procedure with your instructions on my XP and Vista machines.super-poussin wrote: Just a little Information : it will not work with duo THN wrote: Dave, thanks for the great instructions, but I am a little hesitant to go down that road, because super-poussin said: super-poussin wrote: Just a little Information : it will not work with duo
When super-poussin wrote that, I believe he was referring only to the built-in FrontView user interface for enabling UPS sharing (which is present in only the NV+ models). It's true that the Duo does not have this option exposed in the UI, but my instructions (two posts up) should have exactly the same effect as that UI setting.
You don't need to install the SNMP add-on to do this. I have a Duo myself and I can confirm that the UPS sharing is working using the instructions above without any extra add-ons. (SNMP might allow you to monitor other things on the device, but it's not needed in this particular instance.)
If you're nervous, you can always make a backup copy of those config files so that you can revert in the case of trouble (which I'd recommend as a good general practice anyway).- Thanks for the reply essd. I had read your instructions, which are very clear and concise. However, I wanted to kind of stay away from installing the root access. Hence my question regarding the SNMP. If installing that, will allow me to monitor my NAS from a PC, that's really all I need.
When you say:

I think you can now with Raidiator 4.1.5- Anyone here have any tips for building upsmon on OSX 10.5? I'd rather build from scratch than use fink to install.

viewtopic.php?f=28&t=35314&p=196117#p195952 - Sorry to bring up an old thread, but it seems the WinNUT installers for Windows don't work for Win7 64-bit. Is there another method to network UPSes so that the ReadyNAS and Win7 machines can talk? I don't see an "apcupsd" package for ReadyNAS, unfortunately. This would be a great add-on since it's actively maintained for all OSes, including Windows.
Does anyone know of a client for Win7 64-bit that can talk to NUT running on the ReadyNAS?
