Cool. I've never think via this way. I'm sure I'll use it. Thank you for the hint.<br>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...).<br><br>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.<br><br>
