Beta test of new NUT UPS package

Starrbuck

No hurry. It freaked me out for a bit until I figured out I was causing it by going to Snort first. ;)

dennypage

I'm not sure how long the release will take to go through the system, so I sent out a beta4 with the url fix. This should be the same as the pending release except for the version number. If you come across any other issues, please do let me know. Again, thank you for your help!

Starrbuck

Sure thing, glad to help.

I can report that all is working.
But I want report some strange issue, if you are just updating your previous beta then NUT service refuses to start automatically, widget just reports that UPS need attention and you must reboot or wait while it reconnects.

Don't look at "maxage = 25" it's already fixed ;)

Also when I push restart service it restarts and "UPS Status" shows me same alert "Status Alert: The UPS requires attention", if I just hit refresh button in browser — everything coming back to normal state.

Sample log after pushing restart service:

Am I missing something or my configuration is wrong elsewhere?

I have attached one.

The service being stopped on update is expected. The package install is being done outside of pfSense and there is nothing which calls for a start the service after.

I'll have a look at the other issue shortly.

dennypage

w0w, can you check something for me please?

Edit /usr/local/etc/rc.d/nut.sh and remove the ampersand from the end of the line where the driver is started:

/usr/local/sbin/upsdrvctl start

Then perform the service restart test. Thanks.

w0w

It does not change anything visually on Services/UPS/Status — it shows "Status Alert: The UPS requires attention". But log looks much better.

Should we call Services/UPS/Status page refresh with some delay or use some flag memory that /usr/local/etc/rc.d/nut.sh have done it's job already?

I'm not testing this but was hoping I could add some food for thought. Just speaking from my personal experience from running about 5 different pfSense routers for myself, my small business and a family member's small biz. I've used NUT and my typical setup is to have it remotely access the UPS connected directly to my Synology and/or FreeNAS devices. Obviously, because I'm dealing with small spaces and cannot have a dedicated UPS for every device.

My biggest headache has been when things go bad. Example - A pfSense router goes whacky and a fresh install then restore from backup config has to be performed. Typically, this is simple enough. However, I've always had trouble with NUT causing odd behavior with the recovery. I've had to manually edit the config file and remove all traces of NUT content. For the record, I've learned to create backup configs that do not include package data

I'd like to see this new version play nice on recovery if a config does happen to include package data…if possible.

Also, I'm very excited to see a new version and continued development of this package! Thanks DennyPage!

dennypage

Yea, that makes sense. Theres a bit of a catch-22 as the async startup for the driver is required to support the use of startup retry (maxretry/retrydelay) in ups.conf. It's taking a long time for the initial connect to the SNMP UPS.

Beta 4 appears to have the same problem with Snort.

dennypage

Can you confirm the checksum on the following files please?

32332 22 /usr/local/www/nut_settings.php
14138 5 /usr/local/www/nut_status.php
47031 3 /usr/local/pkg/nut.xml
3633 12 /usr/local/pkg/nut/nut.inc

@Starrbuck:

I uninstalled and reinstalled the package and it's ok now.

dennypage

Kinda figured that would do it. Thanks for confirming.

This modification works for me.


$status = nut_ups_status();
if ($status['_alert']) {
	sleep(10);
	$status = nut_ups_status();
		if ($status['_alert']) {
		print_info_box("Status Alert: The UPS requires attention", "alert-danger");
}
}

The other issue I have — head.inc does not show restart service button anymore after successful restart, but if I unplug cable from SNMP card then it shows.

w0w


$status = nut_ups_status();
if ($status['_alert']) {
	sleep(10);
}

$pgtitle = array(gettext("Services"), gettext("UPS"), gettext("Status"));
include("head.inc");
$tab_array = array();
$tab_array[] = array(gettext("UPS Status"), true, "/nut_status.php");
$tab_array[] = array(gettext("UPS Settings"), false, "/nut_settings.php");
display_top_tabs($tab_array);

$status = nut_ups_status();
		if ($status['_alert']) {
		print_info_box("Status Alert: The UPS requires attention", "alert-danger");
}

This way both problems fixed, with buttons and wait for service be ready on page load.

dennypage

Yea, there isn't much ill that a 10 second sleep doesn't fix. However I don't think I can introduce a 10 second sleep in the UX. It creates a delay in communicating the error condition for local UPSs.

Sleep activated only if first $status query return '_alert', else NO DELAY applied. In normal condition if I understand your
nut.inc correctly this never should return '_alert' if connection is OK, it does not matter local or remote connection established.

dennypage

It introduces a ten second delay in all alert circumstances. However the issue we are trying to address only occurs on service start and only with a slow (remote) UPS.

dennypage

Btw, forgot to ask this earlier: Is the use of v2c a holdover from the prior NUT package, or did you explicitly configure it? Have you tried running without it?

@dennypage:

I am not sure are we talking about the same thing? I have tested it with firefox and it works as it should in UX. If UPS connection is OK and established there is no delay in loading status page, I mean delay is less then 1 second and if there is a problem with connection (cable unplugged or whatever), then it returns "Status Alert: The UPS requires attention" as it should be but after 10 seconds delay or returns UPS data if connection is established during this 10sec sleep. Why sleep should be called in all alert circumstances? I don't understand. I am sorry. I am not an PHP programmer, but if logiс is the same for all languages I know. If I do something wrong, then feel free to tell me :)

@dennypage:

It's not from prior, it's required for some other clients on network.

EDIT:
Now I understand what you mean, forgive me please for my stupidity. Looked deeply into nut.inc
Yes we need some other way to fix it.
