setup IP address as "192.168.xxx.xxx" does NOT work.
Someone say I need use "crossover" type of cable, but
I don't have. I put a switch and coneect cable from
each PC and it work fine.
Crossover cables or crossover connectors (those little white connectors
that can be used to connect two RJ45 cables together) can be had at any
'serious' PC store. Also online from many many sites.
I always carry a crossover cable in my travel bag.
Thanks.

use IP asddress 1.1.1.1 and 1.1.1.2.
I check "ifconfig -a" and both eth0 and eth1 are

use
second port (private) and no response. Does

I configure wrong?
Thanks.
