nut version: 2.8.1-3 Hello Laurent,
sometimes it helps to read the documentation :$ In the man page of upsd.conf I read: "LISTEN interface port" ... Multiple LISTEN addresses may be specified. The default is to bind to 127.0.0.1 if no LISTEN addresses are specified (and also ::1 if IPv6 support is compiled in). Assuming upsd is listening on ::1 only, I inserted the line LISTEN 127.0.0.1 into '/etc/nut/upsd.conf' and the UPS can be accessed again. Therefore, I think this bug report should be closed. Could you do that? Thanks for your help and sorry for the noise. Regards, Jörg.
