[ale] home networking difficulties

[Geoffrey]

You might try networking the Linux box to itself.  That is, set the two 
nics to be in the same subnet and connect them both to the hub.  This 
way you might reduce the possible issues substantially.  From that 
point, you could verify the cables/cards are functional.  Is it 
possible, the win box and linux box are trying to talk different speeds? 
  (one 10 the other 100).  I'm grasping now (or gasping??).

I don't know that we can say this definitely just yet.  I would have 
expected that once you shutdown the firewalls on both machines that you 
should have been able to either telnet or ping from one to the other in 
at least one direction.

Agreed, since you did turn off the firewall and make the same attempt.

But pinging yourself more then likely goes the local loop (127.0.0.1) so 
it never touches the nic, wire, or that subnet.

I guess you could uninstall it to insure they're not trying to 'protect 
you from yourself' which seems to be a common thread through windows 
software.

See note above. :)

I didn't have to buy my radio from a specific company to listen
to FM, why doesn't that apply to the Internet (anymore...)?
