I'm sure that a >netcat expert would be able to find a way of executing netcat only once.
Cool. I've never think via this way. I'm sure I'll use it. Thank you for the hint. But a problem could be with netcat software (if it installed or not on the not-NUT slaves, moreover there are a number of Windows hosts). Unfortunately I have no ability to break in configuration and installed software of the not-NUT hosts too deeply (licenses of the suppliers of the hosts, etc...). Thanks to Kris Jordan, I guess the problem is the uid of the upssched (CMDSCRIPT and my shutdown script and ssh) process. I hope I 'd check it as soon as I get connection to the system. > >Roger > >_______________________________________________ >Nut-upsuser mailing list > [email protected] > http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
