Topic: Nut login Failed

[Brave Dave]

I've just installed SME 9 on a new server with a UPS

This appears in the log straight after the ups runs

upsmon[27707]: Login on UPS [UPS@localhost] failed - got [ERR ACCESS-DENIED]

but if I kill upsmon and run it with debug (upsmon -DDDDDDDDDDDDD)
if delivers that error, then continues and shows it is connected and monitoring

I think it's just log noise - possibly as upsmon tries to connect to IPv6

I'm just looking for someone to agree - maybe it's a note for the HowTo

Not an expert here, but a -DDDDDDDDDDD log, plus a config show nut output might help.

Yes - sure - this is output, you can see it starts working, just delivers the message then carries on.

The /etc/ups/* files are as expected

config show nut
nut=service
    AdminPass= 47781907561333
    AdminUser=disabled
    MasterPass=<masterpass>
    Model=usbhid-ups
    SlavePass=<slavepass>
    access=localhost
    status=enabled

upsmon -DDDDDDDDDDDDDDDD

It all seems to work as expected, if I turn power off to ups it sees the outage and monitors

Most likely it is indeed due to ipv6, see also https://forums.linuxmint.com/viewtopic.php?t=97487

IIRC, it is upsd that is listening for incoming requests. What's the content of your:

* /etc/ups/* (remove confidential stuff if you want to)
* /etc/hosts.allow  (remove confidential stuff if you want to)
* /etc/hosts.deny  (remove confidential stuff if you want to)

Michail, please open a bug ticket with your findings as I've seen various threads mention this log noise due to ipv6 too.

The dev team maybe able to suppress this log noise or advise otherwise.

Thanks,

I am not the one with the issue. Brave Dave should probably open a ticket.

EDIT: Missed the not above

[Brave Dave]

Thanks for confirming my thoughts Michail
