Emulate upsmon slave behaviour

[叶踏池]

I have two computers attached to the same UPS. One of which running Linux acting as UPS server, another is a Windows desktop running WinNUT as UPS client. I configured the upsd.users as such:

[server]
    password = 123
    upsmon primary

[pc]
    password = 321
    upsmon secondary

and in upsmon.conf on the Linux machine: MONITOR ups@localhost 1 server 123 primary. After this, I can see in the upsd logs: User server@127.0.0.1 logged into UPS [ups].

However, I can't see this line in the log when I configured WinNUT to the pc user. The connection is made and the monitoring values are displaying correctly, just that the remote upsd never knows there is another client relies on the same UPS. AFAIK this might cause some problems during the FSD sequence.

Reading the documentation seems like the client need to invoke LOGIN <upsname> after setting the username and password to let the upsd know. The user must have upsmon privilege configured in upsd.users or access will be denied. Before shutting down, invoke LOGOUT so the upsd knows that client has been turning off gracefully.

I think this should be nice to have, but for now I can't think of a proper way to add this functionality to WinNUT, like should we add a checkbox to enable this and show error if the account is denied due to no upsmon privilege configured, or we should try to login anyway and just do nothing if it's denied?

Hi,

Thank you for the detailed post. This repository is no longer maintained. You can find the current version of WinNUT here: https://github.com/nutdotnet/WinNUT-Client

As far as LOGIN/LOGOUT is concerned, I believe WinNUT has been doing this for awhile now. Please give the latest version a try, and if you're still experiencing problems, please make a post in our Q&A discussion area and we can go from there.

Ahhhh never realized there is another fork. I'll check it later, thanks a lot!
