[mrtg] Re: OID Math question

Figured it out...Patience and trying to do this remotely was my enemy...And
remember, give it a few cycles before changing your calculations.


Last, Thanks to all for your input (Especially 'eyal at acenet.co.za'), if not
for waiting for your responses, I would have given up on this one..


Here is my config that seems to be working fine...
