I don't have a machine handy to try this one (I'm telnetted
into my Linux box right now; I don't want to 'ifconfig down eth0'
my telnet session!).
If you 'ifconfig up' your NIC, without giving it any parameters
like IP address, does it appear in Ethereal's capture dialogue
popup list? I would think so.
If not, you can still give the 2nd NIC an IP address, just give
it some fake one that nothing should be routed to. This is how
the DOS-based Remote Sniffer product from Network Associates
works; it has one NIC for communication to a central Sniffer,
and one NIC for sniffing. In DOS, you give both an IP address, but
the sniffing-NIC's IP address is bogus.

It should be.
