[lug] talking to a 10.x.x.x box

[Chip Atkinson]

I can only speak from experience with the Cisco 675, but I bet the 678 
is very similary.

The ethernet cable supplied with the 675 was a cross over cable which 
allowed you to connect your computer directly to the 675.  If you get a 
hub you can connect the 675 to the hub using a straight through cable. 
Then connect your computer to the hub as well.  Other computers connect 
to the hub too.  CompUSA had a linksys home office hub kit with hub, 3 
or so nics and cables to string them all together.  You can use the 
crossover cable to connect the 675 into the uplink port of the hub, 
effectively giving you 6 ports instead of the advertised 5.

If you don't have the password for the 678, you are only partially 
screwed.  I don't remember how, but I believe that there is a way to 
jump in through the serial port during boot, but you will have to call 
your DSL provider.

To answer your question about the IP and logs, you won't see any IP 
address other than the one on the computer, unless you have the 678 set 
up to log to the computer via syslog.
