Is your feature request related to a problem? Please describe.
This feature request concerns two issues with the NUT plugin that prevent the diagnostics page, dashboard widget, and API endpoint from returning UPS status data when running in netclient mode.
Problem 1: upsc binary segfaults on FreeBSD 14.x with NUT 2.8.5
The DiagnosticsController::upsstatusAction() method called /usr/local/bin/upsc via configd to retrieve UPS status. This approach fails for two reasons:
1.) configd sanitizes the @ symbol in parameters, making it impossible to pass upsname@host as an argument via configdpRun().
2.) On FreeBSD 14.x with NUT 2.8.5, upsc segfaults (SIGSEGV, exit code 11) when querying a remote upsd server, producing no output before crashing.
This bug has been reported to the NUT project: networkupstools/nut#3454
Problem 2: Bare HostnameField definition in netclient model
The netclient->address field in Nut.xml was defined as a bare address type="HostnameField" with no configuration, which is inconsistent with how other fields in the model are defined.
Describe the solution you'd like
1.) Replace the upsc call with a direct TCP socket connection to the remote upsd server using the NUT protocol. This is more reliable, faster, and bypasses both issues entirely.
2.) Add explicit Required and IpWithPrefix attributes to properly define the field.
This has been done and is awaiting approval in PR #5469 sysutils/nut: fix upsstatus diagnostics and netclient model definition.
Describe alternatives you've considered
A fix for nut 2.8.5.
