I know of no > way around that. This isn't true, and is quite commonly done for IDS systems. You should be able to install the NIC, configure it for a static IP, then simply not assign it one. If for some reason this doesn't work, or you get a 168.246.x.x address, you should be able to counter that by assigning it 0.0.0.0: ifconfig eth1 0.0.0.0 netmask 0.0.0.0 broadcast 255.255.255.255 up We did this all the time for Solaris systems.

If you need it to be COMPLETELY silent, then you will have to use iptables/netfilter creatively to block and and all outgoing packets.
