Everything except rateup is in perl so you can just look at it. For
everything else you can just read the source code which is freely
available. If you're really paranoid fire up your favorite packet
caputuring software and look at the packets being sent out.
But, for getting input/output information it uses the standard MIB-II OID
for ifInOctets and ifOutOctets. Should you be using SNMPv2c then it uses
ifHCInOctets and ifHCOutOctets. Now, the cfgmaker script does several
snmpwalks to determine some stuff automagicailly.
