[Nut-upsdev] lost communication with UPS

[john hart]

Thank you for the reply.  After further reading the NUT documentation I suspect that I cause the problem by reloading upsmon without first stopping the driver. At least that is what I think probably happened.I will avoid doing that in the future. I'm not irrational, I'm just quantum probabilistic.

After making the mod to upsmon.conf I invoked upsmon -c reload and a few minutes later the system shut down.  There was a loss of communications with the UPS.  I have an Asium P700 UPS and use the blazer_usb driver.

Please be more specific about "loss of communication". There are three key connections: upsmon-to-upsd, upsd-to-driver, and driver-to-UPS.

If upsmon loses the connection to upsd, or the driver loses the connection to the UPS, upsmon should not shut down unless the last status message received was "OB".

> As I said, thanks to all the help I received from Charles Lepple, I was able to get this UPS working, and it has worked fine for many months. I know that there is, or will be, an updated driver to replace the blazer_usb driver but I am somewhat dependent on updates as provided from the Debian repositories.  I am running Wheezy 7.9 and am NOT a programmer so I am not comfortable with the idea of downloading source code and compiling it.  Don't really want to upgrade to Debian Jessie as there are older packages that I use that are not available in Jessie, and I don't like mixing packages across distributions.

Not upgrading will limit the scope of any fixes we can provide.

Please resend them, minus any passwords.

Also, from the last email thread: "Another thing: we recently discovered that some Yahoo anti-spam measures result in mass unsubscription of non-Yahoo email users of these lists [this happens after a number of Yahoo emails are received in a certain time window]. Please consider submitting future information from a non-Yahoo email address, or create an issue on the NUT Github project: https://github.com/networkupstools/nut/issues "
