IPTraf is a neat tool but, information it gives should be taken with a grain 
of salt.  If you're looking at "general" statistics, it is going to show you 
the combined IN+OUT as IPTraf sees it.  This IN+OUT is never accurate from 
what I've seen in my tests.  I don't know if it isn't counting encapsulation 
overhead or what its problem is but it is flat out wrong in almost every 
instance.

Now, for looking at flows through/to a box, it is great.  Just don't bank on 
the bandwidth stats being accurate.

I've seen the errors I'm talking about on eth, gige, and ATM OC3 interfaces 
so, it's not specific to any one interface type.
