I'm installing debian 3.1 on a P3 500 with 128M RAM via ADSL, booting
from floppys. When I get to Install base system step, it retrieves and
installs all the core packages, but fails when it gets to "Updating list
of available packages". The log screen has the message:

Err http://> sarge/main Packages
  Could not connect to <mirror> (1.0.0.0), connection timed out.

I have tried 3 mirrors now, 2 local (Australia) and 1 US, all get the
same result. I have no idea where to look for the problem. Why does the
connection time out when it's just spent 20 mins downloading all the
core packages from that same server? And what does the (1.0.0.0) mean?

Thanks for any help,
