Questions using MRTG

[Aeryn <aeryn_sunn hotmail com>]

Hola, I was wondering who has used MRTG to measure bandwidth usage on their
server?  I have it compiled and ready to be used, except I still have a few
questions.  How hard is it to setup snmp on the server?

My box is a linux build.  It hosts numerous Ips all through the eth0
interface, which has its own ip.  The ips that have websites associated with
them are bound to the ethernet card as eth0:0, eth0:1, and so on.

It looks like I would point mrtg to measure what is coming in eth0 and that
would catch all the other ips...is that true? Am I making sense? (be nice)

Any clues are appreciated...

Gracias,
A
