That seems to do a lot of what I want, however our current monitoring tool can
do stuff a lot easier if it were accessible via SNMP.
It seems there is a tool that can help https://github.com/ohitz/dhcpd-snmp
It is a perl script that I somehow need to hook into the net-snmp tool. Has
anyone even done this on a Debian machine, I have not used SNMP on a Debian
machine before and have yet to read all the documentation as to how I can
install a perl script as an extention. Anyone who can help, please do so. What
do I need to focus on at first?
