EatonNmc66102Reboot

#!/bin/sh

# This script conditionally reboots an Eaton NMC 66102 invoking wget under Linux.
# The Eaton UPS network management card is only rebooted in the case that its
# current time is completely wrong. The latter typically occurs after a power-on
# cycle, whereat the network components are powered by the UPS itself such that
# the network is not available right from the beginning. For the usual reasons,
# the card's NTPD refuses to update the time stepping from the year 1970 to now.
# Hence, the card can run with time values near 1970 for a very long time which
# is not desirable, of course.
# The NMC 66102 here has the technical level 15 and the firmware revision HF.
# This script has been tested under Debian Lenny with wget 1.11.4,
# and under DD-WRT v24-sp2 (12/14/11) std - build 18007 on a Gateworks GW2358-4
# router with wget_1.13.4-1_ixp4xx.ipk from http://downloads.openwrt.org.
# No write access is necessary, except for /dev/stdout and friends, of course.

# This script was originally written by Stephan Seidl in 2010,
# no copyright is claimed. It is offered as-is, without any warranty.
# This script is in the public domain; do with it what you wish.

# This script changed in 2012, now accessing the NMC 66102 using SSL.
