Complained, but worked:
dumb:~# ifup eth1
SIOCSIFNETMASK: Cannot assign requested address
dumb:~# ifconfig
eth1 Link encap:Ethernet HWaddr 00:03:47:08:A5:44

I have a dual-homed host spanning two networks and I would like to leave
one of its interfaces unconfigured so that I can use libpcap
applications on that network unobserved. I can do this using the
command string "ifconfig eth1 0.0.0.0 up", but I was wondering if there
was a way to do this using the /etc/network/interfaces file and the
ifup/ifdown commands. If there is, I can't seem to get the syntax.
I use the following syntax, to bring up a MiniPCI wireless network
interface with no address, so it can be added to a bridge. Different
purpose but same idea, I think.
auto wlan0
iface wlan0 inet static
address 0.0.0.0
netmask 255.255.255.254
Nothing actually gets added to the routing table, AFAICT, but it's
necessary to specify a netmask to stop ifupdown from complaining.
