My first thought, exactly. Apropos of this, I have a question...

# tcpdump
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes

What does the EN10MB mean? I'm guessing Ether Net 10 MegaBit per second.

I'm using 100 Base T, so I wonder whether this is just a left-over
and now inappropriate message.
Mike, this begs the question just what or where is the ethernet speed set or regulated?? I'm one of two users on our router to our DSL modem. My roommate's Winders machine runs the web like a bat out of hell, while my machine is relatively slowwww... there must be something I need to tweak, I just don't know where or what. Thanks for any considerations, Ric
