You have! See below ;)

That's precisely the error I get - interesting that it's not limited to the 
last few cvsups.
Is that FreeBSD 4.1.x? 

One curiosity is, you're able to scan using the PPPoE interface, and not the 
LAN, while the
reverse is true in my case. I wonder if it has to do with the existence of 
multiple network 
cards, or multiple types of them?

The plot thickens..
