have you installed nut-snmp package on Ubuntu?
im pretty sure i havent - i will do that right away though Marc!
thank you Marc - that works - always good to have something that works as a starting point on the learning journey

a final question please - when the nethserver connects to the APC UPS unit (assume out of the box config) is it being requested for a password or is this an open (readonly) connection… in which case the password i am creating in the nut config is for other nut clients/slaves to connect to the server. Im just trying to get my head round the highlevel architecture in play here because for instance the upsmon is configured to listen to the local host and not the UPS IP (this caused me issues when trying to configure nut before hacking the nethserver config)
We are really doing the same for each PVE we install for each of our customers; we install NUT directly on the hypervisor, and added a script to shutdown the host in case of missing power for a prolonged period of time. You have to configure NUT by hand, but in the end it shouldn’t be that difficult.
Yes, correct. Your case is definitely much more “lucky”, since you have an APC Network Card which can speak with any number of hosts. Think instead the case in which your UPS can be connected only via USB: you cannot have multiple hosts receiving UPS notifications, but only a single host receives UPS notifications. NUT can work as a “server” and then provide notifications also to other systems in the same network, so you may poweroff any system (which supports NUT, of course; even ESXi IIRC have a vib supporting that) that are served by the UPS.
thanks for feedback Emiliano - would you be willing to share your nut configs and shell scripts from a generic pve - this would save me a load of legwork… thanks in advance, Alex
Hi
I could provide you with some standardized configs for NUT for Proxmox and others.
I use for most of my clients Proxmox as a basis, and Nethserver running inside Proxmox.
I have one client running the NUT Server on Proxmox, all others use a Raspberry PI as NUT Server, the idea being allowing a quick replacement of Proxmox HW in case of problems. The Proxmox are mostly all in Cluster-Config for HA and Failover purposes.
Raspberry and Proxmox are both Debian based, so the same configs and commands work…
I also use Zabbix Monitoring on the NethServer, and NUT is monitored using SNMP (Expanded SNMP).
Andy
thanks Andy
I would be very greatful for anything you can share… ive just installed snmpd and nut-snmp on proxmox server and used the config from nethserver … its done something but its not working yet so ive failed on the quick dirty attempt! (it worked from an ubuntu server so there must be something proxmox in the way!)
thanks in advance for any asistance, cheers, alex

Hi
These are the files I use for a Raspberry, they will work on a Proxmox 1:1.
Replace the existing files under /etc/nut and restart nut (client and server)
hosts.conf (Used for NUT-CGI):
MONITOR ups@localhost “Riello UPS”
nut.conf
MODE=netserver
ups.conf
maxretry = 3
[ups]
driver = riello_usb
port = auto
desc = “Riello UPS”
upsd.conf
LISTEN 127.0.0.1 3493
LISTEN 192.168.175.171 3493
(Use your IP!)
upsd.users
[admin]
password = YourPassword
actions = SET
instcmds = ALL
[upsmon_local]
password = secret
upsmon master
[upsmon_remote]
password = secret
upsmon slave
upsmon.conf
MONITOR ups@localhost 1 upsmon_local secret master
upsset.conf (Needed for NUT-CGI)
uncomment the last section as stated in the text…
Test the UPS with following command:
upsc ups@localhost
This should get you a working NUT server.
The precoded passwords will work out of the box for NethServer and Synology as NUT-Clients.
Synology uses NUT, but the user and password are hardcoded into the OS. So you need to adapt the nut server, like here.
You can add / modify users / passwords / hosts and ups as needed…
Reillo provides a good usb driver, they work well with open source…
Otherwise the standard USB driver will work well with most USBs…
These are my notes specifically for Proxmox:
————————————————————
NUT in Proxmox (As Server)
————————————————————
apt-get install nut-client nut-server usbutils
systemctl status nut-monitor.service
systemctl enable nut-monitor.service
systemctl start nut-monitor.service
nano /etc/nut/nut.conf
MODE=netserver
nano /etc/nut/upsmon.conf
MONITOR ups@192.168.175.62 1 monuser secret slave
systemctl enable nut-monitor.service
upsc ups@localhost
————————————————————
Note about security:
NUT Port should NEVER be accessible from outside the network, don’t open that port on the firewall!
If in a school or hotel like environment, the networks (subnets) for servers should be separated from users.
NUT-CGI can be installed on Proxmox, Raspberry or Nethserver. I prefer it on NethServer, as that server is usually accessible from the Internet, is secured and robust. As the NUT from NethServer connects to the Proxmox NUT, both have the data needed, so you can place NUT-CGI where you want (on whatserver is suitable)…
Hope this helps…
Andy
Andy thats really appreciated - ill take a look today and hopefully get things up and running!
And if you want the whole thing monitored, install Zabbix (See NethServer forum Post / Modules).
Thats part of a Screen specifically for Zabbix UPS, data retrieved with SNMP (Extended)…
Can supply those too, if you need / want them…

Hi Andy thats an impressive output! Id definately be interested in Zabbix - i think I had a go at building a Zabbix VM a little while ago, at least im guessing i did because i have a VM called ZAB1 !.. i recall i never managed to get it to boot… probably a simple mistake but ill take any guidance on this subject because it looks very useful. Thanks again for any assistance, cheers, alex
Hi
MrMarkuz made a module for Nethserver, see here:
https://wiki.nethserver.org/doku.php?id=zabbix
and here:
(Scroll about to the the first third, that’s where it starts to get really interesting…)
Zabbix has a big repo of “modules” or Plug-Ins for monitoring, there are plenty there. I didn’t find one which worked the way I wanted, and wasn’t keen of having russian displays, so I made my own template to use NUT with SNMP-Extended monitoring.
This get’s interesting, especially if you have proxmox running, say on a HP Server with HW-RAID.
Proxmox doesn’t come with say LMSensors or HW-RAID monitoring (Provided by HP, Dell or whatever servers you’re running). LM Sensors will give you nice Temp Info. These info can be used to give you nice graphs, which can help solve problems…
Example: Air-Con defective? CPUs of all Servers and NAS gets warmer and warmer, without much more load…
Install Zabbix, get it up and running on NethServer, and I can provide help on monitoring your UPSes with Zabbix and SNMP.
Note:
The docu on the page at the part “NethServer Zabbix” is missing the repo in the install command, this would be correct:
yum --enablerepo=mrmarkuz install nethserver-zabbix
This command will not find the file:
yum -y install nethserver-zabbix…
Another Client with Proxmox, NethServer, Macs, X-Ray, Dicom-PACS and Zabbix!
See the end of this post for more infos about that network:

Hi Andy ive failed again with zabbix. 1) spun up an nethserver VM. 2) following instructions and ran yum -y install nethserver-zabbix seemingly successfully 3) tried to access the url https://newIP/zabbix
accessing that url fails - im working with a base build of nethserver so i dont know if there some dependencies that need installing also?
Hi
The install command you used did not work for me, as the Repo wasn’t found…
This would work:
yum --enablerepo=mrmarkuz install nethserver-zabbix
Did you follow the instructions from the NethServer modules page including the Repo?
The repo needs to be activated first.
Zabbix will install on a plain vanilla NethServer, http (Webserver) needs to be installed, also an account provider helps. Otherwise no other stuff should be nessarily…
Zabbix should show up under Apps in the standard Dashboard (Port 980) and can be opened from there, as well as using the direct link…
Note:
My last installation was just before the 7.7 upgrade to Nethserver. It works with NethServer 7.6.x, but I haven’t tested installing it on latest 7.7 yet. Maybe somethings broken. Installing a 7.6 NethServer and Zabbix works, and also works after upgrading to 7.7…
My 2 cents…
Andy
PS: Where are you located?
Myself, I’m in central Switzerland at the moment…
Hi Andy
Im located in UK - most winters i spend a good chunk of time in Switzerland (north east of lake Geneva in the mountains but seem to be snowed under with work instead this year!)
I meant to say that I ran the following
yum -y install https://mrmarkuz.goip.de/mirror/mrmarkuz/7/noarch/nethserver-mrmarkuz-0.0.1-3.ns7.noarch.rpm
Then you are able to install/update packages easily:
yum --enablerepo=mrmarkuz install
I just now additionally ran the following command also
yum -y install nethserver-zabbix
and it complained… At face value the zabbix install instructions looked very simple - i.e. just install mrmarkuz’s zabbix module… and for that reason i didnt go into the more lengthy method… im guessing that is required based on errors below??
[root@p10zab2 ~]# yum -y install nethserver-zabbix

Hi
A friend of mine ran into that problem too. Seems MrMarkus needs to update his Repo/Module/Version…
This is an issue since the 7.7 upgrade. It will be solved, but tha can take a few days.
An easier way at the moment would be to install the older Version of Nethserver (Last 7.6 DVD/ISO), there all works - and continues to work after upgrading to the latest and greatest!
As I recall, your NethServer setup is fresh, you don’t have anything to lose, but gain new experience and knowledge.
All other stuff mentionned will work as stated on both versions.
My 2 cents
Andy
thanks Andy, yep i can live with reinstalling especially as you and Markuz have done all the leg work for me!.. im looking forward to firing it up later!
Hi
What part of UK?
(While it still is united… ;- )
A good friend of mine living and working here came from the UK (somewhere close to Welham Garden or such, North of London) is just before pension and his only plus with Brexit is that the Swiss and Brits did a side deal before Brexit, meaning his status quo stays - and so can he!
And what part of Switzerland NE of Geneva? I do know Switzerland like the back of my hand, but I’m also more aware of the UK than a lot of Brits. Last summer I met this guy from Newcastle at a lakeside café in Zug, and had a pleasant chat with him for 2-3 hours. I did ask him where in Newcastle, he replied East, and I pressed: South Shields? The guy was flabbergasted, that I knew about that town, knew about Consett Steel (BS shut down in the 70ies…) and Shipbuilding in South Shields…
He also asked toward the end where did I stay in that area (I never did get close…) - but I picked up the Newcastle “slang” from him… 
OK, drop a line when NethServer and Zabbix are up and running, I can provide a few insights to Zabbix and Monitoring…
Best regards & good progress
Andy
