NUT package (2.8.0 and below)

dennypage

bdf0506, can you please confirm that you haven't modified any of the system or nut scripts by hand? I will have a look at this, but it will be about a week before I can.

Thanks for the reply. I've added a LISTEN section into upsd.conf for another device to query NUT, but that is all. Everything else should be the default.

I'm not convinced this is an issue with the pfsense port of NUT, but perhaps its a NUT configuration setting all together that I am missing. I have noticed that some of the files - especially upsmon.conf are missing a lot of values vs the sample file, but maybe some of those fields are just the default fields.

Here's the config files that I have:


[2.3.4-RELEASE][root@pfSense.home]/root: cat /usr/local/etc/nut/ups.conf

[ups]
driver=usbhid-ups
port=auto

And here is an output of my actual ups device, showing that NUT is working and can connect to it.

If you're not a NUT core developer, chances are that you're told to enable debugging
to see why a driver isn't working for you. We're sorry for the confusion, but this is
the 'upsdrvctl' wrapper, not the driver you're interested in.

Below you'll find one or more lines starting with 'exec:' followed by an absolute
path to the driver binary and some command line option. This is what the driver
starts and you need to copy and paste that line and append the debug flags to that
line (less the 'exec:' prefix).

In package manager, I can see nut is installed, but there is an orange warning "Newer version available", followed by a "Package is configured but not (fully) installed". No update button exists. See attached screenshot.

Something I must do here?

There is nothing you need to do. What you are seeing below the blue line is actually the legend for the entire package list. I.E. what the icons and colors mean. If you only have one package installed, it can be visually confusing.

Thanks for the clarification!

Hello :)

I enabled email notifications, and now I am being flooded by these kinds of messages:

Wed, 14 Jun 2017 19:25:41 +0200 Communications with UPS ups@192.168.2.21 lost Wed, 14 Jun 2017 19:25:46 +0200 Communications with UPS ups@192.168.2.21 established

And there's loads of them, as the attached screenshot shows.
Meanwhile, in system logs I see this:

Nut is acting as a client ("Remote NUT server") to a Synology (the ..300.117) that acts as a NUT-server in the network segment, and which is connected (via USB) to an APC UPS. So, since it is acting as a client, there isn't anything much to configure in the pfSense package.

Would anybody know how I can fix this problem?
Thank you in advance,
Bye,

What are you seeing on the Synology?

Gertjan

With the help off this forum, the Syno forum and the NUT man pages, I hooked up my APC UPS USB to pfSense, pfSense is the "NUT server".
My Syno is the client off pfSense-NUT.
Works great for me.

Btw : it seems to me that you have network errors. And "NUT" complains about it.

Your mail server isn't playing it softly neither ….

Mr. Jingles

@dennypage:

Thank you Denny :P

Syno says nothing, other machines that are clients to Syno UPS-server also don't log anything.

Latest power outage (going on the UPS) was June 9 (per attached pic).

Thank you :D

I've had it the other way around for the past 6 years, which worked fine. That is: I don't recall ever enabling email notifications (which is not to say I haven't done that. Simply don't recall it), which therefor never bugged me before either because the problem never existed in the past - or always existed but was never emailed to me.

Btw : it seems to me that you have network errors. And "NUT" complains about it.

How do you see that I have network problems if I could ask? Would you happen to know what kind of network problems?

Because I don't experience any network problems at all :-[

dennypage

The NUT connection problem, and the SMTP problem are both suggestive of TCP connections being forcibly closed or timing out.

Questions:

Is the Synology that is hosting NUT also hosting your SMTP?
Is the Synology accessed via the LAN interface on pfSense?
Do you have anything set up on pfSense to kill states?
Do you have the firewall enabled on the Synology?
What is between pfSense and the Synology? A switch? Another firewall?

upsmon says you so :
@Mr.:

…..
Jun 15 17:11:35 upsmon 40316 Communications with UPS ups@192.168.300.117 lost
….
5 seconds later :
Jun 15 17:11:40 upsmon 40316 Communications with UPS ups@192.168.300.117 established
…..

These log lines are from upsmon running on pfSense.
"ups@192.168.300.117" is the identity of the server, running on your diskstation (IP 192.168.300.117). This connection (some TCP link or whatever) fails and is reconstructed 5 seconds later.
At least, that's what I make on it.

edit : ah ….
Wait a minute.
your smtp server is running on your diskstation. Using other words : your smtp sever is running on your LAN.
Are these :
..... ups@192.168.300.117 …...
log lines that indicate "smtp handshake" errors ? (being pfSense as a mail client and the app running on the diskstation as the mail server) ?

One big advise : DO NOT, NEVER EVER run a smtp server on a LAN. Live is just to short. I know, a Synology can do many things, but don't make it think it is a (relaying) smtp server. Mail server settings are ..... huge. Far more easy will be : use the mail server of your ISP - or, why not, our your own mail server on a host on the net (your dedicated or VPS server somewhere on the net).
Client to server smtp communication is easy to debug, pfSense is just a pile of PHP script lines when it concerns the smtp transaction so you can find out easily what's up. But then your smtp mail server has to deliver the mail, so it reached out from your LAN to, for example, mail.gmail.com (GMail's mail server) and in that case your "DNS reverse" has to be ok, SPF should be fine, DKIM should be rock solid, and recently you better have your DMARC set correctly.
When I have some time I'll try to activate the "smtp server app" in my diskstation to I can see what you saw ...

Something is interfering with TCP connections between your pfSense instance and the Synology on the LAN. Usually this would be a firewall, but that doesn't seem the case here based on your answers. Best thing I can suggest is to run tcpdump on both, and see if you can at least identify the direction packets are being lost in.

With regard to running an SMTP server in the LAN, I don't see an issue with this. You certainly don't want the SMTP server in the LAN exposed (tunneled) to the internet, but when used in conjunction with a an external server which handles the internet connections it is quite safe. I would consider it as a very common architecture.

I myself use a Synology as the internal IMAP/SMTP server, with Postfix in the DMZ as the external server.

Any chance you've had a chance to look at this? Config files were provided in a previous post. Thanks!

I have. The power kill logic is gone from the base os level. Still searching to find out when and why.

Ah, interesting. Sounds like it isn't an issue with my specific setup and it is a bug affecting anyone trying to use that functionality in the NUT package. Looking forward to seeing a fix for this whenever one can be found.

Gertjan, Are you using link aggregation on pfSense or bonding on the Synology?

Although you asked Gertjan this question, it triggered me, and yes, I had bonding on the Synology. I deleted the bond, and I think the problem is gone. I am looking, but sofar no more emails about connection lost and established.

I'll report back tomorrow, thank you :-*

I was hoping this would also fix another problem I have with shared folder sync over VPN, but unfortunately not. I'll post a new thread for that (edit: it is here, in case you have a spare minute left and would be curious ;D https://forum.pfsense.org/index.php?topic=132628.0).
