# IPMI network module for sysinfo client

# Enter some information about system here

#

# Revision History

#

# 20171124 RWR

# Fixed where STDERR now goes to /dev/null

#

# 20191118 RWR v1.2.1

# in some cases, ipmitool is used only to access other devices over the network

# so it will not have information. Fixed so that if @temp is empty, will just exit

#

# 20230204 RWR v1.3.0

# look for specific IPMI files to determine if the driver is installed

# better than just checking @temp afterwards

#

# module to get network interface information for ipmi

# requires ipmitool (runs ipmitool lan print)

# NOTE: this takes the ipmitool output and parses it, so changes to 

#       this output invalidates this module#

# find our location and use it for searching for libraries. library.pm must be in the same directory as the calling script

# or, if run interactively, in the parent of the modules
