I'm building stealth machines (logger, IDS, etc) without IP addresses and I
need a way to activate an interface without an IP address in a switched
environment.
loading up the module isn't enough to send a broadcast so the switch
negotiates a link and logs the mac. Anyone have an idea on how to send a
broadcast to the switch with nothing setup in /etc/conf.d/net ?
I've been trying mii-diag without success. I'm using the 3c59x driver in
gentoo-sources. Gentoo rc3.
Before I get into modifying the net.eth0 script I would like to see if tehre
is something I'm missing here. :)
Here's a link to what I'm trying to setup:

Any help would be appreciated. When I'm complete with this I will submit it to
the gentoo security docs.
Robert

I think the simplest way is to add "ifconfig eth0 up" in
/etc/conf.d/local.start.
It's quite a specific situation, I don't know if it's worth to put in
default scripts.

in your /etc/conf.d/net

I sure wouldn't mind seeing ifconfig iface down added to static and DHCP
ehternet configs..
