[newbie] 10/100 mb hub won't work

[Rodney]

I have a 10/100MB hub at home. All my computers (NT 4.0 server and
workstation, Win 95) work fine with the hub. I plugged the Linux box into
the hub and it won't work. I switched back to my 10 MB, just to slow for a
power user like me, and it works fine. What gives?
