Hi,
I have 2 ethernet ports embedded on my motherboard. eth0 is configured to
get an IP address via DHCP while eth1 is static. When I plug a cable on
eth1, I can only ping and ssh eth1 [which is what I expect and want], but
when I plug a cable to eth0, I'm able to ping and ssh both eth1 and eth0. Is
there something I'm missing here? Everything seems to indicate that eth1
shouldn't be alive except /sbin/ifconfig.
