NUT package (2.8.0 and below)

Mr. Jingles

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

Questions:

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

@Mr.:

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

Thank you Denny :)

1. Yes.
2. Yes, both in the same LAN.
3. No.
4. No.
5. HP Procurve 1910 switch.

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

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.

@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.

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

dennypage

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.

Correct.

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

@dennypage:

Something is interfering with TCP connections between your pfSense instance and the Synology on the LAN.

@dennypage:

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).

Yep, I addressed the wrong person. Sorry about that.

Anyway, it makes sense. You have a disagreement between the link aggregation group configuration on the Synology and the switch.

The benefit of understanding networking. Thank you for your message :-*

Suggest that you disable all lag/bonding for both pfSense and the Synology (don't forget to disable lag/lacp on the switch ports) and disconnect all but one cable to each system. Then check ping in both directions and confirm that there is no loss.

Hello, I have a Tripp Lite Smart1500LCDT that I'm trying to use with NUT. I have seen NUT connect to the UPS briefly a handful of times and will cycle between online \ offline.

I have tried using the usbhid driver without any extra arguments and with settings found http://networkupstools.org/ddl/Tripp_Lite/SMART1500LCDT.html

Hey f34rinc , seems like you've done some homework. Thanks!

Going forward, the first thing I would recommend for testing is to get rid of everything in the advanced section, and ensure that you have rebooted before continuing diagnosis.

Do you have confidence in the USB chipset on the mother board? Is it a recent MB? It appears that the UPS is on the other side of a bridge chip (expected), but I don't see it's identification in the usb dump. It's not an external hub is it?

Also, how old is the UPS? If it's not recent, have you tried the tripplite driver?

Hi, I'm running a Cyberpower UPS, and getting random email notifications saying LOWBATT, I have NUT running as the master on my pfsense box, with the UPS connected directly via USB. I'm sitting at 100% battery charged and UPS load around 65%. I verified this is reported from the actual LCD screen on the UPS, and uspsc command. Why is NUT thinking the BATT is low, when its not even on BATT, and its reporting 100% charged?

I do not have confidence in the USB chipset the box is a Leonovo M90 3246-A2U from 2010 and I was able to find it uses Platform Controller Hub (PCH) for PCI, ethernet and USB. I've also switched between the USB 2 and USB 3 ports, different cables. I can only get usbconfig to show TRIPP LITE UPS Tripp Lite.

No external USB hub (eww)

I just purchased the UPS July 2017

I do plan to get new hardware in the next year or possibly sooner, I dont know if it would be worth it to try and get a PCI\PCIe usb card with a better chipset.

I've had a couple of Cyberpowers. I found them to be a bit flakey, particularly when the battery needs replacing. It could be happening when the unit does its short self test. I would perform a self test, followed by a runtime calibration to check the battery.

Normally I would recommend against an external hub, but in this case it's worth a try to test with an external (powered) hub because it will be a different bridge chip.

Thanks, is there a certain bridge chip manufacture I should try or avoid ?
