Re: [PLUG] debian install two nic

[marc <marcw2@home.com>]

topology is 10 base t   eight port hub with NAT32 on NT with two nics to a cable modem
3com diags say the card is ok
I will do some hw swapping tonight
eth0 pings and resolves names on internet
eth1 192.168.0.22 can only be pinged from debian machine after
ifconfig eth1 192.168.0.22 netmask 255.255.255.0 up

     does this help you
if I         ifconfig eth0 down        and then
ifconfig eth0 192.168.0.20 netmask 255.255.255.0 up
no other machine can ping 192.168.0.20 until reboot
